To gain these properties, several experiments were conducted on various explants to optimize the concentration of plant growth regulators in regeneration of Gerbera. In the first experiment, regeneration of Gerbera plant was investigated using different explants including intact leaf, petiole, scratched petiole and Thin Cell Layer (TCL). Moreover, combination of BAP (0, 1, 2 and 3 mg L -1 ), TDZ (0, 0.1, 0.5, 0.8 and 1 mg L -1 ) and IAA (0.1 mg L -1 ) under 16/8 h light/darkness condition or one-month darkness were considered. In the second experiment, the regeneration potential of the first, second and third disc of TCL cut off from the end of the detached petioles were evaluated. Effect of different combination of BAP (0, 1 and 2 mg L -1 ), TDZ (0 and 0.5 mg L -1 ) and IAA (0, 0.1 and 0.3 mg L -1 ) on regeneration was studied. In all experiments, the MS-basal medium was used. The results showed that the best regeneration medium for intact leaf (33.2% regeneration, 66.3 shoots), petiole (86.66% regeneration, 33.33 shoots) and scratched petiole (53.2% regeneration, 33.10 shoots) was MS medium containing 2 mg L -1 BAP under 16/8 h light/darkness condition, and for TCL explants (46% regeneration, 29 shoots), 2 mg L -1 BAP with 0.5 mg L -1 TDZ in the darkness. In the second experiment, the highest rate of regeneration was obtained from the first disc of TCL explants on the MS medium containing 2 mg L -1 BAP, 0.5 mg L -1 TDZ and 0.1 mg L -1 IAA.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127587885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This plant has fragrant flowers and leaves. Therefore, one of the most important objectives of this study was to investigate the of crossability of R. iberica with R. damascena and commercial cultivars of Dolce Vita, Avalanch and Red One, as well as embryonic germination and some morphological characteristics of their offspring. This study was conducted to investigate the possibility of crossbreeding of R. iberica with R. damascena and 3 commercial cultivars of Rose Avalanch, Red One and Dolce Vita in a completely randomized block design for hybridization and a completely randomized design for embryo rescue in 5 repeat performed. The results of this study showed that the highest percentage of hip formation and the highest average number of seeds per hip from the intersection of R. iberica with R. damascena was 34% and 13.40%, respectively. Also, R. iberica as a pollinating parent was different from R. damascena seed parent and produced few hip and seeds. The results of crosses showed that the highest height, average number of leaves and green leaf percentage and chlorophyll content were belonged to id5 genotype. The only cross between R. iberica as the pollinating parent and the Red One cultivar as the parent was not successful, and the hips dried up and fell off the plant a few days after the crossing. In the crossings of R. iberica with Avalanch cultivar and also R. iberica with Dolce Vita cultivar, the average number of seeds per hip was 10.20% and 6.80%, respectively, and in the crossings between R. iberica as the pollinating parent with Avalanch cultivar as mother parent and also R. iberica as pollinator parent with Dolce Vita cultivar as mother parent, a large number of seedlings produced in the early stages of growth on MS culture medium were died, and in crossing of R. iberica with Avalanch and Dolce Vita resulted in the highest number of offspring. It can be attributed to gametophytic incompatibility, meiotic abnormalities and accumulation of recessive genes or differences in the ploidy levels of the resulting offspring. Findings of this study showed that R. iberica with production of the highest number of hips and high average seed production is very suitable for selection as a parent and also the resulting genotype is superior to the parent in most parameters studied, which can be used in upcoming breeding program for the traits of flowers, the aroma of flowers and leaves.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"29 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123586965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since diagnosis of medicinal plants growth under different irrigation conditions and drought stress can be a guide for growing plants in dry and low water conditions, the aim of this study was investigating of the effects of drought stress on morphological characteristics and quercetin amount, in different stages of plant growth of C. officinalis L. This research was conducted in Gorgan in a completely randomized factorial design, each treatment with 3 replications. The experimental treatments included three levels of stress (no stress, mild stress and severe stress) in pots under greenhouse conditions, at vegetative, preflowering, flowering, and fruiting stages. After determining the soil field capacity in the pots, the water content was calculated for control pots, and then its content was set at 2/3 for mild and 1/3 for drought stress. The pots were irrigated with the specified amount. After the treatments, plants were pulled from soil and their morphological traits including plant height, root length, stem length, leaf length, number of flowers, and flower diameter were measured. Moreover, their predominant flavonoid production (quercetin) was measured by liquid chromatography. Statistical analysis was performed SPSS software and means were compared using Duncan's multiple range test at 5% level. The results showed decreased plant height, leaf number and area and flower number and diameter, and increased root length by decreasing of soil moisture content at all stages of growth. The amount of quercetin increased in mild stress condition and decreased in severe stress condition at flowering and fruiting stages. The highest level of quercetin (59.11 mg g -1 dry weight) was belonged to mild drought stress at fruiting stage and the lowest level (41.05 mg g -1 dry weight) was belonged to severe drought stress at flowering stage. It can be concluded that plants produce more secondary metabolites in response to stress, and in severe stress, they produce fewer secondary metabolites due to lower plant growth rate.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127337156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The important flowers which are internationally traded include lilium, tagetes, rose, tulip, chrysanthemum, carnation, tuberose, crossandra, etc . Estimation of yield at the time of harvesting of flowers is an important aspect in these floriculture businesses which help strategize their marketing. The present study thus focuses on Lilium and Tagetes (marigold), which are well-known cut and loose flowers, respectively. Cut flowers are harvested when buds start showing color while loose flowers are harvested depending upon the varieties when it attains full size. Conventionally, yield estimations are done manually by counting buds and flowers, which is often erroneous and time-consuming. This paper attempts to develop an automated system for counting Lilium buds and Tagetes flowers at the time of its harvesting using digital image processing techniques. The process implicates image acquisition, pre-processing, thresholding, watershed and finally buds/flower counting for yield estimation. The validation of the results has been done by comparing the results obtained through the manual method as well as by automated counting. The entire process was repeated four times with four different photos to judge the robustness of the techniques. The obtained result was 95.61% accurate for Lilium and 96.66% in the case of Tagetes , airing the possibilities of using the approach. The systematic workflow with pros and cons has been discussed in this paper.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132466015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, population growth and lack of sustainable water resources is one of important challenges facing the arid regions. Change in style and paradigm of landscape design in arid areas with regard to the priority of reducing water consumption, can lead to social discontent caused by xeriscaping and creation of low input green spaces. Rising visual demand in society towards green spaces in recent decades as a result of improper selection of landscape design patterns, especially in dry areas, is the main background for a possible conflict between aesthetic preferences and sustainable green space in this region. In xeriscaping, Integration of effective factors in aesthetic perception with relevant variables in planting design less has been under consideration. Effective factors in aesthetic perception are nine visual concepts include coherence, disturbance, stewardship, imageability, visual scale, naturalness, historicity and ephemera. Seven fundamental principles of xeriscaping are plan and design for water conservation, improve the soil, limit turf area or select alternatives, irrigate efficiently, select appropriate plants and hydrozone plants, mulch to reduce evaporation, maintaining a xeriscape. Despite researches showing that xeriscaping could usually reduce landscape water consumption by one-third however, many people were initially reluctant to substitute it for conventional landscaping. A common perception was that xeriscape were drab and barren and featured nothing more than rocks and some succulent and thorny plants. In this paper, on the one hand the aesthetic preferences of landscape and green space and also options of design in arid regions of Iran have been explored and the other hand, the reasons possible confrontation between these two major issues and suitable strategies for reducing the conflict, has been discussed and analyzed. Among of nine concept of aesthetic that affect social preferences, the concepts of complexity, coherence, imageability and ephemera in green spaces of arid regions, are faced with more challenges than other concepts. Since in the xeriscaping, use of drought-resistant plants is one of the principles so, for low diversity in ornamental plant species and partial removal of lawns and water element in the landscape, aesthetic preferences of citizens, will not be fulfilled completely. Social awareness toward the water crisis in the arid and semiarid regions of Iran, ornamental plant domestication and import of drought resistant species as alternatives and also creativity and innovation in designing of xeriscaping, can decrease the possible dissatisfaction of the citizens from the sustainable and rational development of green spaces in dry climates.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123779983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seed production is very important in oak, because oak seeds (acorns) are main source of food for animals and human. Zagros forests located along the Zagros mountains in western and southern Iran are covered with different species of oak and Brant`s oak ( Quercus brantii Lindl.) is the dominant species of these forests. Since acorn production ability of different oak trees is different due to differences in genetic structure and other influential factors such as site and climate, identification of good acorn producers is very important. In this research, 30 Brant’s oak trees were selected in a part of Poldokhtar forests in Lorestan province, Iran, and their acorn production were studied during 4 years (2014-2017) using crown count method. For sample trees, trunk and crown health characteristics, maturity, single-stem, minimum diameter of 15 cm and no touching of adjacent crowns were considered and their quantitative variables were measured. Two criteria were used to identify good acorn producers: trees that produce acorn each year and their average acorn production were higher than the average acorn production of the stand. Based on the results, the mean number of acorns of sample trees in 4 years was 476.6 and the lowest and highest acorn produced was 0 and 5696, respectively. Also, only one tree had the characteristics of the good acorn producer. The results of this study showed that even with 3 years of acorn production monitoring in Brant`s oak trees can be identified with acceptable accuracy of native good acorn producers. In this research, good acorn producers of Brant`s oak were identified in a part of the forests of Lorestan province and the necessary recommendations for their conservation is discussed.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131289043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
