戒台寺和潭柘寺古树衰老的几个生理特征研究

通过对戒台寺和潭柘寺的卧龙松、自在松、抱塔松、活动松等油松及九龙松 (白皮松 )、娑罗树 (七叶树东西 2棵 )等古树的树体温度、叶绿素含量、叶及土壤矿物质含量等生理参数进行测定 ,与 40a生的油松、白皮松、七叶树进行对比 ,得出如下结论 :1 )树木的衰弱程度与其树体温度有一定相关性 ,即越衰老的树木树体温度越高 ;2 )老树的叶绿素含量一般均比对照低 ;3)衰老古树呈现明显的缺素症状。

Research on Several Physiological Characteristics Related to Senescence of Paleo-trees in Jietai and Tanzhe Temples

This paper mainly studies some physiological senescence parameters regarding paleo-trees from wolong pine, zizai pine, baota pine, huodong pine (Pinus tabulaeformis) , jiulong pine (Pinus bungeana) , suoluo trees (2 Aesculus chinensises in east and west), in Tanzhe and Jietai temples such as temperature in tree body, content in chlorophyll and carotenoid, contents of mineral nutrition in leaves and soils. Through comparison with 40 year-old corresponding trees, which are growing in the same environment. It concludes that: 1) There are certain correlation between temperatures in tree body and tree weakness i.e. The more senescent, the higher temperature in tree body. 2) The content of chlorophyll in leaves are generally lower than the controls. 3) There exists obvious nutritional deficiency symptom in senescent paleo-trees.
