黄藤和单叶省藤苗期生长特性研究

Study on Growth Traits of Daemonorops margaritae and Calamus simplicifolius at Seedling Stage

[目的]研究2种棕榈藤苗期的生长特性。[方法]对收集的黄藤和单叶省藤半同胞家系进行苗期生长特性的分析。[结果]方差分析结果显示,除了单叶省藤芽长性状在家系内不存在差异,其他性状各家系间和家系内都存在极显著的差异。2个藤种的年生长趋势分析显示:黄藤叶片数和最大叶长的生长与气温呈显著正相关,单叶省藤叶片数的生长与气温呈显著正相关,2个藤种的叶片数和最大叶生长趋势相似。黄藤和单叶省藤苗期生长最快的月份分别是7月和6月。[结论]2藤种叶片数与气温呈显著正相关,大气湿度对2藤种的生长影响较小。

Abstract [ Objective ] The growth traits of two Rattans at seedling stage were studied. L Method j The variation oi growth traits were lnvest^gatea based on the field data of progenies of Daemonorops margaritae and Calamus simpliciJblius families. [ Result] The results revealed that differences in all seedling traits of two Rattans seedling were significant at 0.01 level among and within families, except that of sprout length of C. simplicifoli- us within families. In analysis of the growth trend, air temperature had correlations with leaf number and largest leaf lengtb for D. margaritae, but only with leaf number for C. simplicifoIius. The growth trends of C. simplicifolins of largest leaf length and leaf number were always same as that of D. margaritae. The fast growth of D. margaritae and C. simplicifolius were at July and at June respectively. [ Conclusion] Air temperature had cor- relations with leaf number. Atmospheric humidity has less influnce on the two Rattans.
