人工倾斜杨树应拉木内源激素分布规律的初步研究
Preliminary study on distribution of endogenous hormones of the tension wood in artificially inclined Poplar
摘要
Abstract
In order to investigate the distribution of endogenous hormones between the regions of tension wood and opposition in inclined stem of poplar, five endogenous hormones I.e.indole-3-acetic acid (IAA), gibber ellic acid (GA3), indole-3-butyric acid (IBA), abscisic acid (ABA) and zeatin (Z) in cambium of inclined poplar stem were determined by high-performance capillary electricity (HPCE) in different months. The results showed that the maximum value of IAA content was reached in June; the regulation of distribution of IAA in tension re gion and opposite region in different inclined angles was the same; the maximum value of IAA content was reached in inclined angle of 30°,while the minimum value was reached at 45°; the content of IAA in opposite re gion was higher than it in the tension region in different inclined angles except the angle of 30°; the maximum value of GA3 content was reached in April, the content of GA3 in opposite region was higher than it in tension region within a year; the content of GA3 in opposite region was higher than it in tension region in inclined angles of 15°and 30°; the content of IBA in opposite region was higher than it in tension region within different seasons and in different inclined angles; the distribution of content of ABA(except December) and Z(except December and inclined angle of 15°) was the same as the content of IBA.关键词
