【摘要】 对红松种子的9项形态特征指标研究发现,不同产地之间种子在外种皮厚、千粒重、种长、种宽、种厚、长宽比、长厚比、宽厚比、种皮比例9方面差异显著,气候因子影响种子的千粒重、种长、种宽、种厚、长宽比、长厚比,而地理因子影响外种皮厚、千粒重、种长、长宽比、长厚比、宽厚比、种皮比例。更多还原

【Abstract】 9 morphological characteristics of seed of Pinus koraiensis were studied intensively.The results showed that there were significant diversities among morphological characteristics of seeds from different provenances.Climatic factors affected 1000-seed weight,length of seed,width of seed coat,the thickness of seed,length/width and length/thickness,while geographic factors affected the thickness of seed coat,1000-seed weight,length of seed,length/width,length/thickness,width/thickness and proportion of seed coat.更多还原
