| 摘 要： | 通过对未开割胶树进行2％乙烯利刺激，在刺激后的6 h、12 h、24 h、48 h、72 h和CK （未用乙烯利刺激）割胶，分析对橡胶树无性系热研7-33-97幼龄开割树的乳胶生理影响。结果表明，乙烯利刺激稀释胶乳后72 h发生强烈稀释，蔗糖在刺激后48 h开始大量转运进入乳管；乙烯利刺激不同时间后割胶，与对照CK相比：随着割胶刀次递增，干胶含量递减，蔗糖、无机磷（除刺激24 h和72 h外）和硫醇含量在第2刀出现1个最低点，随后逐步升高。差异显著性分析表明，刺激72 h后割胶与短时间刺激干胶含量差异显著，长时间刺激（24 h）后割胶与短时间刺激（6～12 h）割胶蔗糖含量差异显著，72 h内刺激割胶无机磷含量差异不显著。故涂乙烯利刺激72 h后割胶较合适。

| Abstract: | To investigate the rubber tree clone reyan 7-33-97 latex physiology effected by ethrel stimulation , this study focused on untapped rubber tree treated by 2%ethrel.The results showed that ethrel stimulation diluted latex effected intensively after 72 h and abundant sucrose were transformed into laticifer cells after 48 h of stimulation.The result of CK tapping experiment showed that dry rubber content had a progressive decrease followed by continuous tapping cuts, and sucrose, inorganic phosphorus （except 24 h and 72 h） and thiol content was at the lowest point in the second cut , then gradually increased .The significant difference analysis showed latex dry rubber content after 72 h stimulation had significant difference with short-term stimulation , sucrose content after 24 h ethrel treatment had significant difference with those of 6-12 h stimulation, the processing of Pi content was not significant difference within 72 h stimulation .Therefor , after ethrel stimulation , the suitable tapping time is 72 h later. |
