In the context of tremendous changes in the world community, one of the main factors is introduction of new plant varieties for reliable development of agriculture. To improve the quality of adaptive capabilities of thermophilic pumpkin crops in the Middle Urals, grafting on resistant stocks can be used. The studies were carried out in 2018-2020 on protected ground, at Udmurt Federal Research Center of the Ural Branch of the Russian Academy of Sciences, the city of Izhevsk. The soil is organo-mineral, humus content is 5.0 %, pH - 5.8. The total plot area is 24 m2, the record area is 16 m2. The repetition was fourfold, the placement of the plots was randomized. The experiment is one-factor. Experimental variants are: 1. Momordica charantia L. without grafting (control), stocks - 2. Cucurbita pepo L., 3. Cucurbita maxima Duch., 4. Cucurbita moschata Duch., 5. Cucurbita ficifolia Bouche., 6. Lagenaria siceraria Molina , Standl. This work presents the stages of the study on compatibility of Momordica charantia when it was grafted onto various types of stocks, based on the analysis of the characteristics of growth and development, survival and productivity of plants. Conclusions were made about the prospects of growing Momordica charantia indoors. The data obtained indicate a high survival rate of Momordica charantia - over 72 % of the studied stocks. At the same time, it should be noted that the highest survival rate among grafts had Cucurbita maxima variant. The dry matter and total sugar content in the fruits of Momordica charantia increased in all variants with grafting (to 26.8 % by dry matter and to 16.2 % by total sugar, respectively) compared to the control, and the accumulation of nitrates was maximum - 384.6 mg / kg in the variant of grafting on Lagenaria siceraria, while there was no excess of MAC. |
