不同无土栽培基质配比对仙客来生长的影响 总被引:1,自引:0,他引:1
为了筛选出适合仙客来栽培且价格低廉的无土栽培基质。以仙客来栽培品种彩云为试验材料。选用4种基质材料(蛭石、珍珠岩、椰绒、草炭)配成8种栽培基质进行对比栽培试验。试验结果表明,以草炭∶珍珠岩=3∶1作为栽培基质,在植株高度、叶片数、开花数、冠幅、花葶高度及花朵数量等参考指标方面均表现较佳。 相似文献

Cyclamen leaves and petioles explants were cultured on MS media supplemented with different concentrations of 2, 4-dichlorophenoxyacetic acid (2, 4-D) or 1-naphthaleneacetic acid (NAA) to induce callus. The effect of 2, 4-D on shoot regeneration was also studied. Either in media containing 2, 4-D or in media containing NAA, callus was observed, but the quality or quantity of callus induced by 2, 4-D or NAA were different. The callus induced by 2,4-D was white, compact and having powerful multiplication capacity. The callus was inclined to browning then was poorly organogenetic. While the callus induced by NAA was yellowish in appearance. It was pultaceous and proliferated bradytelicly. The callus usually can give rise to many shoots. But the frequency of inducing callus of 2, 4-D is higher than that of NAA. The regenerative plantlets derived from the callus respectively induced by 2, 4-D or NAA were transferred into rooting medium. The frequency of rooting were no difference. 相似文献
