| MORPHOGENETIC ANALYSIS OF SQUASH CULTIVARS UNDER LOCAL CONDITIONS
K. Rahymberdi al-Farabi Kazakh National University Rahymberdikymbat@gmail.com Squash is a promising crop, which is frequently attributed to vegetables as it is a broad term encompassing a number of different food types , including pumpkins, courgettes , and zucchini. It has a number of overlapping characteristics and belongs to the genus Cucurbita. The individual species include dozens of cultivars such as buttercup, hubbard, cushaw, summer, autumn, and winter squashes. Other cultivars are referred to pumpkin and zucchini. The squash is a commonly cultivated vegetable crop to be in different areas of Kazakhstan in winter and summer seasons. It bears beautiful flowers possessing usually orange colour. Squash plant extracts contain a range of phytochemicals including saponins, flavonoids, alkaloids, and steroids. Carotenoids are known for their diverse biological effects functioning as antioxidants preserving eye tissues from damaging by free radicals. Main source of carotenoids is plant food, and the carotenoid abundance in plasma is essential for maintenaining tissue viability in the long run. Pumpkin, zucchini squash, and yellow squash combined with some other plant and egg sources may be regarded as major sources of carotenoids and the vitamin A. Modern reviews outline some of the basic growth-analysing techniques to describe different benefits as attempts to summarize investigations on genetical, morphological and ecological impacts of productivity and the relationships of these factors to the nutrition quality of the ten most important species of squash. The aim of this study was to propagate the seeds, evaluate cultivar’s development and health of the plant population, predict the input of cultivar’s growth and yield, according to the plant growth characteristics. Samples were investigated over the whole vegetation season. This experiment was performed at the research plot in Almaty region apart from the plot at the al-farabi Kazakh National University`s Agrobiocenter in 2017. In order to determine major plant growth characteristics related to the leaf area index in squash varieties, present study has been carried out by using a randomized complete block design with two replications, and two planting dates ( May, 21 and June, 21). Leaf area (LA), leaf number per plant, leaf length, width and some other parameters were estimated. Our data have shown that the linear model would predict significant relationships between leaf parameters including LA and leaf length, leaf length and leaf number per plant, leaf length, leaf width, and leaf area. These relationships can be used for the squash simulation models to clarify the leaf growth dynamics for every squash cultivar under cropping. Research adviser: Prof. Z.G. Aytasheva |
