Effects of Living Pterocypsela laciniata and Its Straw on Soluble Sugar Content in Grape Seedlings under Selenium Stress

Type: conference-paper
Abstract: The pot experiment was conducted to study the effects of soluble sugar content of grape seedlings under selenium stress by intercropping and the application of straws in soil. There were five treatments: grape seedlings monoculture; intercropping with Pterocypsela laciniata and applying leaf, stem and root straws of P. laciniata in soil with grape seedlings, respectively. By analyzing, the results displayed that the soluble sugar content in root and stem was markedly lower than that in leaf and shoot. In five treatments, intercropping was significantly increased the soluble sugar content compared with the control. It promoted the growth and the nutrient substance of P. laciniata. On the contrary, applying root, stem and leaf straws of P. laciniata in soil reduced the soluble sugar content of grape seedlings. Obviously, applying P. laciniata straws could not improve the growth of P. laciniata. The content of soluble sugar was always ranked as: grape seedlings intercropping with P. laciniata seedlings > grape seedlings monoculture > applying the leaf straw of P. laciniata in soil with grape seedlings > applying the stem straw of P. laciniata in soil with grape seedlings > applying the root straw of P. laciniata in soil with grape seedlings. In a word, intercropping with P. laciniata seedling was a best treatment for improving the growth of grape seedlings compared to applying P. laciniata straws.
