Abstract:This experiment chose 3 kinds of pumpkin(black seed pumpkin, brown seeds pumpkin, white seed pumpkin)as cucumber(Cucumis sativus L.)root stocks. Each 2 of them were combined as cucumber rootstocks. Cucumber plant growth, yield and wax powder characteristics were studied. The results indicated that, compared with self-rooted cucumber seedlings, the growth and yield of the cucumber grafted with double root stocks was obviously strengthened. But the yield diversity showed different compared with cucumber grafted with single root stock. The yield of the cucumber grafted with white and black seed pumpkin was much higher than the others, significantly higher than the cucumber grafted with black seed pumpkin or white seed pumpkin single root stock. The yield of cucumber grafted with black seed pumpkin and brown seeds pumpkin was significantly higher than the cucumber grafted with single brown seeds pumpkin root stock, but there was no significantly difference compared with the cucumber grafted with single black seed pumpkin root stock. There was no significantly difference between the yield of cucumber grafted with double root stocks which were brown seeds pumpkin and white seeds pumpkin and the cucumber grafted with single brown seeds pumpkin or white seeds pumpkin root stock. The influence on the cucumber surface wax powder was obvious different between the 3 kinds of pumpkin root stocks, black seed pumpkin had no de-waxing powder ability, brown seeds pumpkin had stronger de-waxing powder ability, while color of the cucumber grafted with brown seeds was bright green, without wax powder and it was a good merchandise. The wax powder influence on cucumber grafted with double rootstocks lies between the cucumbers grafted with 2 single rootstocks, and tends to the heavier wax powder root stock.
