McLachlan","doi":"10.4172/2376-0354.1000180","DOIUrl":"https://doi.org/10.4172/2376-0354.1000180","url":null,"abstract":"Despite the extensive use of dwarfing rootstocks in commercial apple cultivation worldwide, it is presently unknown how different growing environments may modify the first expression of rootstock-induced dwarfing of the scion. To address this, we measured the growth and architectural development of compound ‘Royal Gala’ apple trees grafted onto three different vigour clonal rootstocks (‘M27’, ‘M9’ and ‘M793’), grown in three locations of New Zealand. Detailed architectural measurements were made over the first year of growth after grafting and the study was repeated for a second year. Within each site and year, trees on ‘M793’ had the greatest primary axis length and node number, trunk cross-sectional area, number of sylleptic shoots and final tree dry weight, while those on ‘M27’ had the smallest. Trees on dwarfing rootstocks generally had a higher frequency of flowering than those on ‘M793’. Our results demonstrate that the effect of dwarfing rootstocks on sylleptic shoot growth, flowering, and dry weight is highly plastic in response to the growing environment. Across all rootstock genotypes, the scion bud type had a strong effect on tree growth: trees that developed from a vegetative scion bud (monopodial primary axis) had a final dry weight 15-45% greater than those with a floral scion bud (sympodial primary axis). One rootstock-induced effect that was consistent between sites and years was that dwarfing rootstocks caused earlier termination of primary axis growth. This provides novel information about the physiological processes that apple dwarfing rootstocks modify.","PeriodicalId":15920,"journal":{"name":"Journal of Horticulture","volume":"335 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79230544","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 research was conducted at vegetable research plot, Department of Agricultural Technology, The Oke-Ogun Polytechnic, Saki, between 2nd July and 30th September, 2015. Soil treatments consisting of three levels of tillage passes (0, 3 and 6) equivalent to 1.7, 1.3 and 1.5 g/cm3 soil bulk density respectively, four levels of 15-15-15 NPK fertilizer rates (0, 100, 150 and 200 kg/ha) and replicated three times in a completely randomized design. The results showed that no-tillage pass had significant effect on bulk density, zero tillage reduced the percent uptake of N(0.58-0.46), P (0.002-0.0005) and K (0.13-0.04), however, statistically, the reduced effects were more pronounced on Nitrogen and Potassium. Fertilizer rates significantly improved percent uptake of N (0.11-0.58), P (0.0004-0.005) and K (0.04-0.07). Interactions (tillage passes × fertilizer rates) effects were observed on plant height, stem girth,fresh weight, root length and percent N, P and K uptake, but T2F2 (6 passes × 150 kg/ha) significantly increasedplant height and improved uptake of Phosphorous, therefore, 6 passes and 150 kg/ha 15-15-15 could be more suitable for optimum production for Amaranthus viridis on a sandy clay soil.","PeriodicalId":15920,"journal":{"name":"Journal of Horticulture","volume":"3 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85100923","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}

There is little research on determining leaf area in Muscadine grapes that could be used to assess canopy balance. Previous research on nondestructive methods of assessing canopy leaf area in V. vinifera L. and V. labrusca L. varieties may not apply to V. rotundifolia and Florida hybrid varieties. Thus this research sought to verify the accuracy previous non-destructive methods for V. rotundifolia and Vitis spp. varieties grown in Florida. Linear measurements were taken on fully expanded leaf of ‘Blanc Du Bois’ (Vitis spp.), ‘Carlos’ (V. rotundifolia Michx.) and ‘Southern Home’ (interspecific V. rotundifolia × V. vinifera hybrid). Maximum length and width were used to predict leaf area using linear regressions. For each cultivar, 5 linear regression equations were developed to estimate leaf area using length and width. Length and width were log transformed and an additional 3 linear equations were developed. Equations with the product of length and width had a higher coefficient of determination for all three varieties. Therefore, these equations are recommended for use when conducting non-destructive leaf area measurements of muscadine and Florida hybrid grape varieties.","PeriodicalId":15920,"journal":{"name":"Journal of Horticulture","volume":"61 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81114506","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 first study primarily focused on consumers’ perceptions of a foliage plant and various purchasing conditions. The second study focused on accessories featured with a foliage plant in a retail setting. These studies revealed elements that appealed to each study's population as a whole, to specific demographic groups, and to different segments of the overall populations. Through both studies, the concept of \"buy one, get one free\" was of strong interest to the majority of participants. Elements related to consumer benefits, such as “this plant has been proven to improve the indoor air quality of your home,” received the highest overall interest in study one, while elements related to plant containers, sleeves, and value garnered high overall interest in study two. Sorting the data by various demographic groups revealed a multitude of differences in consumer preference for foliage plants and plant purchasing experiences, which allow for targeted marketing by foliage plant retailers. K-clustering revealed separate and unique segments in each study. Study one resulted in a larger segment of the sample population (61%) primarily interested in consumer benefits, while the smaller segment (39%) was chiefly interested in plant care. Study two produced a segment (57%) interested in monetary value, as well as a segment (43%) drawn to plants bred by renowned breeders and promoted by sources such as Better Homes and Gardens. These observations will allow nurseries and retailers to customize the plant purchasing experience according to specific consumer preferences, thereby increasing consumer engagement and reinforcing purchasing decisions.","PeriodicalId":15920,"journal":{"name":"Journal of Horticulture","volume":"1 1","pages":"1-15"},"PeriodicalIF":0.0,"publicationDate":"2016-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89408974","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}

It was hypothesized that germination percentage of Pistacia chinensis is unrelated with substrate types used for propagation and removal of seed coats prior to sowing. Matured seeds of Pistacia chinensis with protective seed coats were sown on standard soil mixtures (SSM) that comprised 3% top soil, 2% cow dung and 1% sand and germination was compared to seeds with protective seed pods that were sown on composted farm yard manure (FYM). Two independent experiments were conducted in completely randomized design with four replications each replication containing hundred pure viable seeds. The study results showed that germination percentages of the treatment group (seeds with protective seed coats sown on farm yard manure) were significantly higher at alpha <0.05 than the control group (seeds with protective seed coats sown on standard soil mixtures). In a separate experiment seeds without pods were also sown in replicates on standard soil mixture and their germination was compared to intact seeds (Seeds with their pods) sown on standard soil mixture. Germination percentages of seeds without pods was significantly lower as compared to the control groups( intact seeds) at P<0.05.The study revealed that the most viable means of propagating Pistacia chinensis under the nursery conditions of Debre Zeit was sowing seeds with pods on farm yard manure. The likely explanation for this could be composted farm yard manure is an approximate simulation of the forest floor . Height and collar diameter of trees averaged 194.61 cm and 4.82 cm at Debre Zeit and thus were found significantly higher than their counterparts (141.1 cm height and 3.35 cm diameter) at Wondo Genet in the across location performance study. There was no significant difference between survival percentages at Debre Zeit (82.6%) and Wondo Genet (90.6%). Carbon was estimated through height and diameter measurements of trees on research plot and subsequent calculations using established allometric relations. The total amount of carbon sequestered by planted trees at Debre zeit amounted to 1.33 tons/ha/year.
