EFFICIENCY APPLICATIONS OF DOMESTIC PUMPKIN ROOTSTOCKS FOR GRAFTING CUCUMBER IN PROTECTED GROUND

Аннотация

When growing herbaceous vegetable crops in the world practice, great importance is given to the use
of grafting method. The development of environmentally safe methods to increase the yield and resistance of plants
to adverse growing conditions is very relevant in vegetable production. One such method in pumpkin crops is
grafting. The aim of our work was to study the effect of domestic pumpkin rootstock on growth, development and
yield characteristics of cucumber hybrid using grafting method. Grafting on pumpkin species improved the growth
and development of plants depending on the rootstock, compared with rootstock plants. The aim of our research was
to study the influence of domestic pumpkin rootstock on the growth, development and yield characteristics of the
cucumber hybrid (scion). As a scion, the variety (Asylum), recommended for cultivation in protected ground
conditions, was used, which was grafted on five domestic rootstocks: 1 (Mozoleevskaya 10), 2 (Karina), 3 (Aphrodite),
4 (Mindalnaya) and Russian selection 5 (Stofuntovaya) pumpkins from vegetable and melon crops. According to the
generally accepted method, the graft was grafted (cucumber Asylum) on the rootstocks of pumpkin. Using a sample
of pumpkin 1 (Mozoleevskaya 10), flowering began on the fifth day earlier in comparison with non-grafted plants,
and when grafting on a sample of pumpkin 4 (Aphrodite), the fruit ripened earlier by six days. To get the greatest
increase in early productivity by 30%, it is possible to use both rootstocks. A significant increase in total yield was
provided by samples of rootstocks 2 (Karina) – 3.9 kg/m2
and 3 (Stofuntovaya) - 8.0 kg/m2
. The grafted cucumber
plants with all the rootstocks used were superior to the root ones in height, in terms of the percentage of
marketability of fruits and in terms of fruit weight. At the beginning of fruiting on grafted cucumber plants, the
number of female flowers increased depending on the sample. In all grafted plants, the dry matter content in the fruit
increased significantly. Because of our research, rootstocks 2 (Karina) and 3 (Stofuntovaya) were noted, which are
recommended for use in further research breeding work and the production of grafted plants.
