The Change of Main Latex Nutrients of Rootstock in Different Yield Rubber Tree
摘要
Abstract
The change of latex nutrient in rootstock on supper-high-yield, high-yield and CK rubber tree (PB86) was applied for exploring the relationship between rootstock and yield. The dry rubber content, soluble solids content, thiols content, sucrose content, and inorganic phosphorus content in rootstocks of each tapping were determined during the period of stimulus tapping. The main results showed that the nutrient content of higher yield rubber trees such as the dry rubber content, soluble solids content, thiols content and sucrose content in rootstock were higher relatively, and that for the supper-high-yield rubber trees were very significantly higher than the CK. The dry rubber content and soluble solids content for high-yield rubber trees were very significantly higher than the CK while the inorganic phosphorus content in the rootstock of supper-high-yield trees were the lowest.关键词
