| 摘 要： | 在天麻开花时，对略阳红秆、绿秆、乌秆天麻3种变型的花果期，花茎、花被筒及子房的长度，果实、种子及胚的长度、宽度等进行了观察研究，结果发现：天麻的这3种变型在每个方面都有一定的差异，乌秆天麻花茎最高，果实和种子最长，开花、结果日期最晚；红秆天麻花序轴、每株结果数、果实重量和种子直径最大，开花、结果日期最早；绿秆天麻花、果期最短，而胚的长度和直径却最大。 |

| Abstract: | Anthesis period,scape length,perianth tube length,ovary length,fruit length,and seed and embryo length and width of G. elata Bl .f. elata,G. elata Bk.f.viridis Makino and G. elata Bl. f. glauca S. Chow were investigated in the flowering period and it was found that the three variants differed in all these traits,G. elata Bl. f.glauca S. Chow having the highest plant,the longest fruits and seeds,and the latest flowering and fruiting date,G. elata Bl. f.elata having the longest rachis,the greatest number of fruits per plant,the heaviest fruits,the biggest seed diameter,and the earliest flowering and fruiting dates,G. elata Bl. f. viridis Makino having the shortest flowering and fruiting periods,the longest embryos and the biggest diameters. |
