The Features of Endogene Hormone in Culm of Phyllostachys edulis ‘Pachyloen’ in Its Leaf-expansion Stage
摘要
Abstract
The composition and contents of endogenous phytohormones in the culm of Phyllostachys edulis ' Pachyloen' at different heights in its leaf-expansion stage were studied. The results showed that the phytohormones ordered (μg/g) by the content in its leaf-expansion stage culm were that GA3 (77. 30 ±5. 81) > IBA (4.36±0.85) > IAA (3.21 ±0.73) > ZT (2.63 ±0.26) > 2-ip (2.22 ±0.35) > 6-BA (2.01 ±0.28) > ABA (1.40±0.10). In general, the contents of endogene hormones (2-ip, GA3, ABA, 6-BA and ZT) decreased with the decreasing of height. The contents of 2-ip, GA3 and ABA decreased remarkably at both the upper and basal parts, and slightly at the middle parts and that of ZT decreased faster at the upper parts than at both the middle and basal parts. In addition, the content of 6-BA decreased linearly. The sequences ordered by the contents of IAA, IBA were central section > the end > the basal. Extremely significant correlation was found between GA3 and 2-ip (R =0. 854, P <0. 01) , and the correlations between ZT and GA3, ZT and ABA were all significant at the 0. 05 level.关键词
