3个紫薇品种花粉离体培养与萌发研究
in vitro Culture and Germination of Three Cultivars of Lagerstroemia indica L.
摘要
Abstract
[Objective] The research aimed at investigating the in vitro culture and germination of three cultivars of Lagerstroemia indica L. [Method] The pollen of three L. Indica cultivars ' Hongiefeiwu', ' Cuipanjinwei' and ' Zizhuayinwei' in full flowering stage was collected as materials to study the effects of in vitro culture on pollen viability and germination. [Result] The optimum medium for L. Indica pollen germination was 150 g/L sucrose + 60 mg/L boric acid + 20 mg/L CaCl2 +20 mg/L MgSO4 + 100 mg/L KNO3, in which, the concentrations of sucrose and boric acid could significantly influence the pollen germination. In addition, the vitality of pollen at long filament differed from that at short filament, wherein, the vitality of pollen at short filament of ' Zizhuayinwei' and ' Hongdiefeiwu' was higher than that at their long filament, while 'Cuipanjinwei' showed the opposite result. Within 2 -6 h after pollination self, pollen germinated to form pollen tube, which grew fast firstly and then slowly. [Conclusion] The study provided theoretical reference for breeding new L. Indica cultivar.关键词
