本文结合生产研究云南松在异常温度下(-5.2℃左右)受害的反映。主要描述1.云南松冻害后所反映出的形态特征。2.从外部形态特征,判断植株受害的程度。3.受害程度与海拔高度的关系。4.在相同海拔高度下,不同受害程度,分生细胞破坏的象征,以及生活细胞中物质的动态变化。5.从受冻植株解剖反映的特征,了解植株冻害后恢复的可塑性大小。从而了解云南松受冻的内外原因。以及内外条件的相关性,进一步判断植株恢复的可能性,为冻害后的营林措拖提供理论依据。
This article combines the production of Yunnan pine in the abnormal temperature (-5.2 ℃) victims of the reaction. Main Description 1. Yunnan pine damage reflected after the morphological characteristics. 2. Judging the extent of plant damage from the external morphological characteristics. 3. Degree of victimization and altitude relationship. 4. At the same altitude, different degrees of victimization, symptoms of meristematic cell destruction, and the dynamic changes in living cells. From the frozen plant anatomical characteristics of the anatomy to understand the plasticity of plant recovery after freezing injury size. To understand the internal and external causes of Yunnan pine frozen. As well as the correlation between internal and external conditions, to further determine the possibility of plant recovery, to provide a theoretical basis for forestation after frost damage.
