升温情境中叶损对树木幼苗生长的影响
Effects of Defoliation on the Growth of Tree Seedlings Under Warming Condition
摘要
Abstract
In order to explore climate warming could counteract the negative effects of defoliation caused by insects to some extent,the height growth of Larix gmelinii,Pinus koraiensis and Abies fabri seedlings under different defoliation degrees in current year and the budburst in the next year under different temperature were compared by using control variable method.The results showed that the height growth of L.gmelinii in the current year was significantly affected under 50％defoliation,while did P.koraiensis and A.fabri under 75％defoliation.At ambient temperature,the bud phenology of L.gmelinii in the next year advanced than that at 20℃ and 25℃,and the height growth was better.At ambient temperature(13℃～18℃),the bud phenology of P.koraiensis and A.fabri was delayed and the height growth was affected by 75％defoliation,while the adverse effect of defoliation was counteracted at 20℃ or 25℃.Therefore,in the future warming scenario,it was speculated that the adverse effects of defoliation caused by insects on P.koraiensis and A.fabri would be counteracted to some extent,and the resistance to a insects nd recovery would be significantly higher than that of L.gmelinii.关键词
