Abstract
ABSTRACT In this study, ploidy levels were determined by stomatal observations and flow cytometry analysis of plants polyploidised by the application of 0.05% colchicine to seedlings at the first true leaf stage. In the study of developing polyploid watermelon rootstocks, the survival rate of the plants was 77%, and the polyploidisation rates were 11% and 3% according to stomatal observations and flow cytometry analysis, respectively. According to the results of flow cytometry, 22 polyploid genotypes were determined. Auto- (12) and allotetraploids (10) of Citrullus genotypes were developed, and their plant growth performance was determined in hydroponic culture in comparison with diploids, commercial rootstocks (RS841, ‘Argentario’) and watermelon cultivar (‘Crimson Tide’). Putative tetraploids and their diploid controls were grown in hydroponic culture for 21 days, and their vegetative growth performances were determined. The results showed that the increases in plant biomass depending on polyploidisation were 100% in autotetraploids and 156% in allotetraploids as compared to diploid controls.
期刊介绍:
Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
