| 摘 要： | 对橡胶树高产抗寒新品种云研77-2、云研77-4早期(1-7割年)产量特性研究结果:开割后产量逐年大幅上升,产量水平高于对照品种GT1,在第4割年开始乙烯利刺激割胶后,产量大幅下降,低于对照;云研77-4产量变化幅度最大,云研77-2次之,对照GT1变幅不明显,表现出云研77-2、云研77-4早期高产,产量增幅大和不耐乙烯利刺激的产胶特点;对乙烯利刺激不同的耐受力是橡胶树品种重要的产胶特点之一。 |

| Abstract: | Two new rubber clones were studied to find out their latex dynamics during early tapping period(in the years of 1 to 7 after tapping).It reveals that latex yield of both clones Yunyan77-2 and Yunyan77-4 getting increase greatly in the first three years after tapping,which is obviously higher than control.Then there is a yield decrease drastically when stimulants begin on the tree from the fourth year.During the early tapping years,clone Yunyan77-4 shows great change in latex yield,Yunyan77-2 is in sequence.Control GT1 shows no clear change.This indicated that the two recommended clones have high latex yield in the early period but have poor performance to ethylene. |
