摘要:
 考察死皮植株割线症状、胶乳产量及各胶乳生理参数,评估1-MCP对橡胶树死皮防控效果。结果表明,施用1-MCP死皮植株割线症状得到显著好转,其死皮长度恢复率为54.44%,死皮指数由试验前的69.33降低为试验后的41.33,防效达48.47%;死皮植株胶乳产量显著增加,试验前后,处理和对照单株胶乳产量分别为:6.40、37.6 mL和10.33、4.87 mL,处理植株单株增产31.2 mL,而对照植株减产5.46 mL。从胶乳生理参数来看,施用1-MCP后死皮植株的各胶乳生理参数得到不同程度的改善,其中胶乳硫醇含量的改善达显著水平。综上所述,施用1-MCP有利于改善死皮植株胶乳生理状况,增强其产排胶潜能,对防控橡胶树死皮、增加胶乳产量具有相对较好的效果。
Abstract:
 1-MCP was applied to the prevention and control of tapping panel dryness (TPD) occurring in Hevea brasiliensis trees.The effects were evaluated by investigating the tapping cut symptoms of TPD plants,latex yield and physiological parameters of latex.The results showed that the tapping cut symptoms of TPD plants treated with 1-MCP improved significantly,the recovery rate of TPD length was 54.44%,the index of TPD decreased from 69.33 (before the experiment) to 41.33 (after the experiment),and the control effect reached 48.47%.The latex yield of TPD plants increased significantly.The latex yields of treated and control plants before and after the experiment were 6.40,37.6 and 10.33,4.87 mL,respectively.The yield of treated plants increased by 31.2 mL,while the yield of the control plants decreased by 5.46 mL.The latex physiological parameters of TPD plants improved in varying degrees after the application of 1-MCP,and the latex thiol content improved significantly.In conclusion,the application of 1-MCP can improve the latex physiological status of TPD plants,enhance their latex reproduction and latex flow potential,and have a relatively good effect on preventing and controlling TPD of rubber trees and increasing latex yield.
