Application results of cucumber grafting on different rootstosks of pumpkin

At present it is very actual in vegetable growing the development of highly effective and ecologically safe methods for increasing yields and plant resistance to unfavorable growth conditions. One of these methods is grafting. The goal of the study was to learn the influence of the rootstock on the characteristics of the growth, development and yield of cucumber. Research was conducted in 2015-2016 in greenhouse in spring-summer period in Armenia. As a scions was used cucumber variety Nazrvan, which was grafted on 5 pumpkin rootstocks (VI033637, VI03338, VI03364, VI040903, VI056328) from the collection of the World Vegetable Center (WVC). The grafting was carried out according to the standard method. When the VI033637 rootstock was used, flowering started 5 days earlier than the ungrafted plants, while when grafted on VI040903, the fruits ripened 6.2 days earlier. High increase of early yield (33.3%) received when used both above mentioned rootstocks. VI033638 -4.1 kg/m2 and VI033664-9...
