Primary Exploration on The Tube Grafting Technique of Cucumber ‘Nan Shui 2’
Abstract: ‘Nan Shui 2’ is a special mini-cucumber variety cultivated by Nanjing Agricultural University for facility cultivation. It has light green and thin pericarp, good merchandise, and it is suitable for four seasons protected cultivation. However, ‘Nan Shui 2’ cucumber is not resistant to the major soil-borne diseases, such as blight and root-knot nematode. Grafting method can improve the resistance of fruit cucumber. In this experiment, use the fruit cucumber varieties 'Nan Shui 2'as the scion, the white seed pumpkin ('Yong Zhen 8') by the Ningbo Academy of Agricultural Sciences as the stock for the tube grafting and the plug grafting. The suitable seedling age of the scion and rootstock were screened, in order to compare the condition of growth and development of grafting seedling after the tube grafting and the plug grafting.The results showed that the graft survival rate of grafted rootstocks was 90.6% in the cotyledon, and the growth rate was the strongest among other eight treatments.The survival rate of the tube grafting was 3.1％ higher than the plug grafting, and the growth potential of the plug grafted seedlings was also stronger.So the best graft age of seedling of stock is in the first true leaf has just grown up , the scion incotyledon have not flattened.Compared with plug grafting, tube grafting has the higher survival rate and the better growth potential.
