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、乳管堵塞指数和黄色体破裂指数等生理指标亦有相应的变化
The yield and physiological effects of early stimulants used in China are studied. The results showed that ethephon was used to excise the seed at the young cutting stage. The first year showed the physiological effect of high sugar and high yield, but the second year showed the fatigue physiological effect of low sugar and low yield. The sucrose content, Physiological indices such as the tube blockage index and the yellow body rupture index have corresponding changes
