摘要:
以我国的‘马铃3’和日本的‘藤九郎’、‘金兵卫’、‘黄金丸’及‘岭南’5个银杏品种枝桠为试材,对其应压木及对应木管胞形态和微纤丝角的径向变化趋势进行了研究。结果表明:5个品种管胞双壁厚和弦向直径从髓心至树皮基本呈增大趋势,变化曲线呈“V”型或“N”型;应压木径向直径从髓心至树皮一直增大,而对应木先增大后减小;壁腔比从髓心至树皮大体呈增大趋势,腔径比则相反;微纤丝角随年轮的增加逐渐减小,曲线大体呈“N”型或“∧”型;应压木的双壁厚、径向直径和微纤丝角均较对应木大,而弦向直径较对应木小。利用SAS软件分析发现:应压木和对应木壁腔比及腔径比差异性均不显著,其余指标间差异性均达显著或极显著水平。对管胞各个特征综合分析发现:‘岭南’径向生长速度最慢,‘马铃3’最快。
Abstract:
The radial variation trend of tracheid morphology and microfibril angle of compression wood and opposite wood of branches from five Ginkgo biloba L. cultivars including “No.3 Horse Bell” from China, “Tengjiulang”, “Jinbingwei”, “Huangjinwan” and “Lingnan” from Japan were studied in this paper. The results showed that the variation trend of double wall thickness and tangential diameter was increased basically from pith to bark, and the curve presented “V”type or “N”type. The radial diameter of compression wood increased gradually, however, the radial diameter of the opposite wood was increased at first and then decreased. The variation trend of the ratio of cell wall to cavity was increased from pith to bark, but the variation trend of the widthdiameter ratio was opposite. The microfibril angle decreased gradually with the increase of growth ring, the curve presented “N”type or “∧”type. The double wall thickness, radial diameter and microfibril angle of compression wood were bigger than that of opposite wood, but the tangential diameter was opposite. It was found from the analysis results of SAS software that the differences of other indexes between compression wood and opposite wood were significant except cell wall/cavity ratio and width/diameter ratio. It was shown from the analysis results of all the characteristics that the growth rate of ‘Huangjinwan’ was the slowest and “No.3 Horse Bell” was the fastest among the five cultivars.
