This plant holds a prominent place in the economic significance of this particular plant family. This study aimed to examine the process of root development and rhizome production through leaf cuttings of zamiifoliain the this experiment. This experiment was conducted as factorial design within a completely randomized framework design with three replications. Experimental treatments composed of chitosan application at three levels (0, 250 and 500 mg L-1), and the positioning of leaflet cuttings along the main axis of the mother leaf (apical, middle, and basal). After the application of the treatments, the leaflet cuttings were subjected to a four-month rooting period. This rooting process took place in a growth medium consisting of a balanced mixture of perlite and cocopeat mixed in a volume ratio of 1:1. The results exhibited significant effects of different chitosan concentrations on several parameters, including rhizome number, rhizome width, the number of roots, and the quality of the mother leaf. In addition, the type of leaflet cutting demonstrated a significant influence on the width and number of rhizomes. These results demonstrated that the application of chitosan at concentrations of 250 and 500 mg L-1 had a positive effect and resulted in increased rhizome number, rhizome width, and number of roots. Overall, it can be concluded that chitosan can promote the growth and development of zamiifolia by stimulating rhizome production and improving root proliferation.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337197","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}

Seeds of M. armeniacum only germinate (70%) by 15 min sulfuric acid plus 45-day stratification treatments. Based on the analysis of variance and mean comparison data that only were reported in M. neglectum, their seeds optimally germinated by 5 and 15 min sulfuric acid treatment plus 45-day stratification.

The experimental design was entirely randomized.

The following characteristics were evaluated: shoot height (cm), root length (cm); stem diameter (mm); number of leaves; leaf area (cm2); shoot, and root as well as total dry matter (g). Shoot/root ratio was determined and Dickson Quality Index. The data were submitted to variance analysis and the means were compared using Tukey’s test at 5% probability.

Understanding the factors that support sustainable flower production is essential for dahlia growers to increase their profits. Two key variables that define leaf development during the vegetative phase of a crop are the rate of appearance of leaves on the main stem and the final number of leaves. The objective in this study was to determine the phyllochron and the final leaf pair number (FLPN) in cut dahlias cultivars grown in different locations. Three on farm experiments varying from two to eight cut dahlia cultivars were conducted during two years (2021/2022) in six locations in Rio Grande do Sul State, Southern Brazil. The number of unfolded leaf pairs (NLP - an unfolded leaf was assumed when the foliolates edges were not touching anymore) on each plant was counted once or twice a week, depending on the farm, until the last leaf pair was unfolded. The NLP was linearly regressed against TT (thermal time °C day-1) and the phyllochron (oC day leaf pair-1) was calculated as the slope of the linear regression. The results indicated that the phyllochron of dahlia cultivars varied between 45.7 to 95.6 °C pair of leaves-1 and 8 to 14 of final number of pair of leaves in the first experiment, 27.2 to 97.4 °C pair of leaves-1 and 6 to 15 of final leaf pair number in the second experiment and 46.8 at 106.4 °C leaf pair-1 and 6 to 13 the final leaf pair number in the third. Thus, there was no significant difference between the sites in the phyllochron and NFP variables.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337264","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}

Moreover, the ex-situ conservation of palm seeds can cause loss of viability over time. The present study aimed to evaluate the biometric characterization and the effect of storage on the seed germination of the Triangle Palm (Dypsis decaryi), a widely used species in Brazilian landscaping. Two independent studies were conducted: I) biometric characterization of diaspores and II) effect of storage in seed germination. For biometry, a sample of 100 diaspores was used and the length, width and thickness were measured. Biometric data were analyzed using descriptive statistics and correlation analysis. The seeds were packed in transparent plastic bags kept in a refrigerator (20 ± 2 ºC and 80% relative humidity) for storage evaluation. The experimental design was entirely randomized. The treatments consisted of six storage periods (0 - control, 30, 60, 90, 120 and 150 days); there were four repetitions and 25 seeds per plot. The germination percentage and germination speed index were evaluated. Diaspores showed little variation in their biometric characteristics, with a mean of 18.39 mm in length, 16.10 mm in width and 15.96 mm in thickness. There was significant and positive correlation between all biometric characteristics. It was observed that germination remained stable until 30 days of storage (90%), with a gradual percentage decrease in later periods. The seed storage allowed to maintain its viability and longevity with the ability to germinate, reaching a germination percentage of 63% after 150 days of storage.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337173","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}
