橡胶树3种割胶制度的产排胶特性变化比较
Physiological Characters of Latex from Hevea brasiliensis under Three Tapping Systems
摘要
Abstract
Thirty mature virgin rubber trees (Reyan 7—33—97), divided into 3 groups, were exploited respectively with S/2 dl, S/2 d3 and S/2 d5 tapping systems. Rubber yields and latex physiological characters were analyzed in the first 10 tapping. Results showed that in 1 to 6 tapping, rubber yields increased successively. In the same tapping, the differences of rubber yield between three tapping systems did not reach significant level. In 7 to 10 tapping, rubber yields of S/2 dl and S/2 d3 tapping system varied slightly but came to stabilization, while those of S/2 d5 tapping system kept increasing. Invertase activity in latex C-cerium increased in 1 to 7 tapping and then came to stabilization. In 1 to 10 tapping, ioial solid contents decreased, nonorganic phosphorus contents and thiol group contents increased. Sucrose contents decreased in 1 to 6 tapping and then increased. Total solid content was significantly negatively correlated to rubber yield when higher than 40%, but not correlated to rubber yield when lower than 40%. The trends of total solid content, non-organic phosphorus content and thiol group content in 1 to 10 tapping were favorable to the catalytic reaction of invertase.关键词
