Distilled water and 2% sucrose were considered as controls. Factors such as membrane stability index, polyphenol oxidase activity, petal browning intensity, flower quality and stem chlorophyll during 9 days of storage were evaluated. The concentration of 1 mM GABA significantly maintained the quality of the flowers. The lowest stability index was observed in the distilled water control treatment. The treated flowers with 1 mM GABA showed significantly less browning intensity than distilled water and sucrose controls. No significant difference was observed between the chlorophyll content of control and GABA treated samples.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127758372","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 results showed that the highest values of plant height, shoot fresh weight, shoot dry weight, number of leaves, average leaf area, number of inflorescences, petiole length and apparent quality rating were belonged to P50 treatment. The highest values of root fresh and dry weight and root volume were obtained in P25C25 mixture. The highest leaf area ratio (LAR) and relative leaf water content (RWC) were belonged to P50 treatment and the highest amount of chlorophyll was belonged to P25L25 mixture. In general, the best vegetative and flowering performance of plants were observed in P50 treatment (containing loamy soil (35%), perlite (15%) and peat moss (50%)) and then in P25C25 treatment. Therefore, with little access to peat moss, less than 50% of peat moss can be replaced with cocopeat, and more cocopeat has a negative effect on plant growth. Licorice residue had a negative effect on most of the measured indices.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123236203","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 order to study the effects of gibberellic acid and humic acid on growth, flowering and vase life of Lilium LA Hybrid ‘Original Love’, an experiment was conducted as factorial in a completely randomized design with 2 factors, 16 treatments and 3 replications. The first factor was gibberellic acid at 0, 150, 300 and 450 mg L -1 which was carried out by immersing bulbs gibberellic acid for 24 hours. The second factor was humic acid, at 0, 200, 400 and 600 mg L -1 as foliar application at the beginning of sprouting every two weeks. The results showed that the effect of gibberellic acid treatment on bud number and flowering stem height was significantly different from control. The highest bud number (5.04) and flowering stem height (79.08 cm) were obtained by treating gibberellic acid at 450 and 300 mg L -1 , respectively. Gibberellic acid and humic acid treatments effects separately showed significant differences on fresh weight of cut flower, total soluble solids and percentage of cell membrane stability index. Also, the interaction effect of gibberellic acid and humic acid treatments caused a significant increase in chlorophyll index (67.70 spad value), vase life (13.66 day), total chlorophyll (0.370 mg g -1 FW), chlorophyll a (0.266 mg g -1 FW), chlorophyll b (0.103 mg g -1 FW) and petal carotenoids (0.026 mg g -1 FW).

The importance of this study is to facilitate the mass rearing of this predatory mite. To evaluate the mass rearing of this predator, its life table on eggs, nymphal stages and adult mites of Carpoglyphus lactis Linnaeus under conditions of 25 °C, 70 ±5% RH, 16:8 (L: D) was examined. Demographic parameters of A. swirskii including: r , λ and R 0 when feeding eggs, nymphal stages and adult were estimated. Therefore, r parameter for feeding at different growth stages of dried fruit mite was estimated in mass production part. In addition, 20 treatments with different compounds with presence and 20 treatments without presence of dried fruit mite with three replications in a completely randomized block design with mass rearing method and intrinsic rate of increase ( r ) for all treatments were estimated and analyzed. Survey of egg life table, nymphal and adult stages of dried fruit mite showed that A. swirskii has the ability to mass rearing on all three developmental stages of dried fruit mite. Life table parameters, A. swirskii including: r , λ and R 0 when feeding on dried fruit eggs were estimated to be 0.165 d -1 , 1.173 d -1 , and 12.95 eggs/individual, respectively. The results of life table parameters, especially r , showed that dried fruit mite has the potential to be a suitable intermediate host. Furthermore, the artificial diet of treatment number 20 without the presence of dried fruit mites is suitable for mass breeding of this predatory mite as an alternative method.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125145283","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}

With completion of genome sequencing of many ornamental plants and astonishing progress on site-specific edition, the process of diversification for ornamental plant breeding will accelerate. Nowadays, due to the ease in application, low cost, and availability, CRISPR/Cas has overtaken the other genome editing technologies such as ZFNs, TALENs and meganuclease. CRISPR/Cas is an acquisition immune system in archaea and some bacteria wherein bacteria in response to introduced genetic materials start to make small complementary transcript by which intercepts the existing invasive sequence and inactivates the target DNA with the help of Cas nuclease protein. Broken strands join together by DNA repair system but the mutated nucleotides lead to inactivity of the target gene. The most important achievement of this technology in ornamental plants so far is knocking down homeotic genes involved in plant developmental process and also color change in petunia, torenia, gentian, orchids, and Japanese morning glory. With further development and optimization of this method, we will soon see many changes in the breeding of biotic traits resistance.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124189006","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}

To develop the floriculture of Iran, it is necessary to change production from the traditional methods to the new methods. The two cities of Andimeshk and Dezful are the main producers of rose cut-flowers in Khuzestan province. In this study, by field investigation and collecting data from the structure and control of environmental conditions of the greenhouse, methods of growing and maintenance of rose cut flowers, yield, conditions of growers in these two cities, present suggestions to increase yield. The data were collected from 60 commercial greenhouses producing roses in a completely randomized and referral to Agricultural Organization of Khuzestan Province. The results showed that the cooling system in 45% of Andimeshk greenhouses and 35% of Dezful greenhouses was fan and pad system. It was found that 50% and 41% of Andimeshk and Dezful greenhouses use Polar systems respectively and opening and closing the valves for temperature balance were usual. The results of irrigation system showed that the Andimeshk greenhouses used 40% gravity, 30% flooding, 20% drip and 10% hydroponics and Dezful greenhouses used 86% atmospheric stack irrigation and 14% drip irrigation. According to the obtained results, it was found that 50% of Andimeshk and Dezful greenhouses have a plastic cover with metal structures. The average annual production of cut flowers in Andimeshk and Dezful was 120,000 and 130,000, respectively. Also, the main markets for selling cut-flowers of roses were the local sales market and Tehran, and their export abroad was done through the Tehran market. The obtained results showed that 10% of the producers of Andimeshk city and 12% of the greenhouse producers of Dezful city have academic education. In conclusion, most greenhouse management operations are performed traditionally and the use of new methods; especially in cooling, irrigation and feeding systems to increase the yield and quality of flowers is essential. It is also suggested that introductory courses in the field of greenhouse management and breeding and maintenance be seriously considered.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523454","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 aim of this study was to investigate the effects of cultivar, explant type, plant growth regulators and culture medium on in vitro propagation of Phalaenopsis orchid. Experiment was conducted using 4 combined treatments of benzyladenine (BA) and indolebutyric acid (IBA) (BA 2 and 4 mg L -1 with IBA 0.5 and 1 mg L -1 ), 2 culture media (MS and Chen), 2 types of explants (leaf and stem), and 5 commercial cultivars of Phalaenopsis orchids. The findings revealed that the studied factors had significant effects on leaf and root primordia initiation, number of protocorms, and number of leaves and roots. Among the investigated cultivars, 2 cultivars: Nottingham and Dubrovnik showed earlier leaf and root primordia initiation. Two treatments including BA+IBA (2+0.5 mg L -1 and 2+1 mg L -1 ), and Chen culture medium showed faster primordia initiation significantly different from the other treatments. Leaf explants produced more protocorm than stem explants. The highest number of protocorms was belonged to Nottingham cultivar, and the treatment of BA+IBA (2 to 1 mg L -1 ) on Chen culture medium. The number of leaves and roots of in vitro plantlets were significantly affected by various factors so that, Dubrovnik had more leaves and the Nottingham had more roots than the other cultivars. The highest number of leaves was observed in BA+IBA (2+0.5 mg L -1 ) treatment, while the highest number of roots was belonged to BA+IBA (2+1 mg L -1 ) treatment. Comparing the media, Chen medium showed more positive effects on leaf and root number than MS medium. The results of this study indicated that the success of regeneration of Phalaenopsis cultivars in vitro is influenced by the characteristics of the cultivar, medium, and plant growth regulator treatments. Nottingham cultivar and leaf explant showed better regeneration rates in vitro . Increasing the concentration of BA from 2 to 4 mg L -1 , increased the time required for leaf and root primordia initiation and prolonged the in vitro cultivation period.","PeriodicalId":229540,"journal":{"name":"Flower and Ornamental Plants","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125760865","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}
