橡胶树新品种热研7-33-97早刺激产量和生理效应研究初报

Study on Yield and Physiological Effect of Stimulation in the Early Stage on New Rubber Clone,Reiyan 7-33-97

试验研究了我国大推新品种热研 7- 33- 97提早使用刺激剂的产量效应和生理效应。结果表明 ,该品种在幼龄开割期使用乙烯利刺激割胶 ,试验第一年表现出高糖高产的生理效应 ,但第二年即表现出低糖低产的疲劳生理效应 ;测定的胶乳蔗糖含量。

The result of early stimulation of cv Reiysn 7-33-97 shows that the physiological effect of high sugar and yield express in the first trial year,but tire effect of low sugar and yield appears in the second year Content of the sucrose in the latex,the stopping exponent of latex vessel,breaking exponent of lutoid and other physiological index also have relevant change
