野生秋橄榄果实形态变异分析

The Analysis of Morphological Variations on the Fruits of Autumn Olive

以烟台市野生秋橄榄为材料,应用方差分析、相关性分析,对11个单株果实和种子11个形态学性状进行研究。结果表明,供试秋橄榄果实和种子的11个性状在11个单株间均存在极显著差异,其中变异系数最大的是果肉鲜重(变异系数CV为22.08%),其次是单果重(CV为15.94%);性状最稳定的是种子干重(CV为2,43%),其次为种子横径(CV为4.31%)。各形态学性状间果实横径与单果重和果肉鲜重和平均果肉率均呈极显著正相关,可从果实横径对单果重及果肉鲜重进行预测。

11 morphological parameters were analysed using variance and correlation analysis on the fruits and seeds of 11 wild autumn olives plants from Yantai in this paper. The results showed that there were extremely significant differences existing in the 11 morphological parameters among the 11 plants. The fruit fresh weight showed the high coefficient variation （ CV 22.08% ） and fruit weight （ CV 15.94% ） was following. Seed dry weight and seed transversa diameter showed the high stable traits （CV 2.43% and CV 4.31% ）. Fruit trans- versa diameter and fruit dry weight and fruit fresh weight were highly significant positive correlation. The fruit transversa diameter could be used for predicting fruit dry weight and fruit fresh weight.
