摘  要:
[目的]研究紫丹参花粉活力和柱头可授性。[方法]通过扫描电子显微镜观察花粉粒的形态特征,采用TTC染色法测定紫丹参花粉活力,并通过联苯胺+过氧化氢反应液和3%过氧化氢测定其柱头可授性。[结果]紫丹参的花粉粒为椭圆形,具有6条萌发沟,表面具有网孔状雕纹;花粉活力最强的时期是散粉时期。在散粉初期,紫丹参均具有较高的柱头可授性,雄蕊开始萎蔫柱头可授性达到最强。[结论]该研究可为紫丹参的育种与扩繁提供指导。

摘  要:
[Objective]Pollen vitality and stigma receptivity of Radix Salvia Yunnanensis were studied.[Method] The pollen submicroscopic morphology of Radix Salvia Yunnanensis was observed with scanning electron microscopy( SEM). Pollen vitality of Radix Salvia Yunnanensis was evaluated by TTC.Stigma receptivity was estimated by the method of Benzidine-hydrogen peroxide and 3%hydrogen peroxide. [Result]The shape of pollen grain of Radix Salvia Yunnanensis was elliptic with 6 germination grooves and the surface has a mesh pattern. The period for strongest pollen vitality was pollinating period by using TTC for Radix Salvia Yunnanensis. The pollen receptivity of Radix Salvia Yunnanensis generally was higher in early pollinating period,and the stigma with the strongest pollen receptivity of period of stamens began to wilt.[Conclusion]The research can provide guidance for breeding and expanding propagation.
