| 摘 要： | 将新引进的日本矮紫薇与本地品种紫薇、红薇、银薇进行栽培对比试验.结果表明,日本矮紫薇播种发芽率达85%,幼苗移栽成活率为90%,生长发育规律与其他栽培种相同,但开花较早,且花期长达100d,越夏度冬后,存活率在97%以上;温室河沙为基质进行嫩枝和硬枝扦插,日本矮紫薇生根率达90%.通过评定生长规律、繁殖条件和观赏价值,认为日本矮紫薇在武汉地区具有良好的适应性.

| Abstract: | Annual and biennial seedlings of newly introduced Lagerstroemia indica cv.have been studied and analyzed in the area of Wuhan.The results are as follows: compared with the three native species L.indica,L.indica var.rubra,L.indica,var.alba,Lagerstroemia indica cv.has a germinating rate of 85% and a high survival rate of 90% in open field cultivation,its annual growth increment and development increases regularly with the time.It blooms earlier and has a longest flowering period of 100 days.After summer and winter,Lagerstroemia indica cv.has a high survival rate of more than 97%.Young shoot cutting and hardwood cutting on sand showed the best rhizogenesis rate of 90%.So Lagerstroemia indica cv.has a good adaptability in Wuahan according to its growth rhythm,reproductive condition and ornamental characteristic. |
