8种落叶栎类种子形态特征比较分析
Comparison and Analysis on Morphological Indices of 8 Species of Deciduous Oak Seeds
摘要
Abstract
The morphological indices of 8 species of the deciduous oak (Quercus variabilis , Q. acuthsima Q. aliena var. acuteserrata, Q. fangshanensis , Q. liaotungensis , Q. mongolica , Q. robur and Q. palustris ) seeds from Beijing, He'nan, and Shaanxi were examined. Six morphological indices including weight, length, diameter, peridium length, diameter of cupule scare and volume were measured. The seed morphological index variation of different species were analyzed and compared. The mean values of the a-bove-mentioned morphological indices of the oak seed were (2. 66 ± 0. 80)g, (20. 70±1. 51)mm, (14. 65 ± 2. 07)mm, (2. 82 ± 0. 91)cm3, (8. 90 ± 2. 27)mm, and (9. 93 ± 2. 02)mm, respectively. Significant differences were observed in all morphological indices among different species, provenances and individuals, and there existed significant and close correlations among the indices. Three common morphological indices, including seed diameter , seed peridium length, and seed length, were suggested.关键词
