彩色马蹄莲促成栽培技术研究

在不同的温度、赤霉素(以下均用GA3)浓度、光照强度以及其作用时间的不同等条件下,处理冬季和夏季处于休眠状态的彩色马蹄莲种球,结果表明,在冬季,GA3处理能促进彩色马蹄莲种球的萌芽和开花,开花率达40%以上,GA3 低温和GA3 高温 光照处理能显著提高种球开花率,其中GA3 高温 光照处理30 d的种球开花与生长效果最好。在夏季,种球的发芽率与是否用GA3处理无明显差异,但是,不用GA3处理的种球都不开花,用GA3处理的种球开花率均为100%,并且,花产量随处理温度的不同而不同,其中,以低温 GA3处理花产量显著高于其他处理。

Studies on the technique of forcing culture of colorful common Callalily (Zantedeschia)

Dormant bulbs of colorful common callalily(Zantedeschia) were treated with different temperatures,gibberellin and illumination in winter and summer seasons.Results showed that in winter,the dormance of bulbs could be breaked by gibberellin at the flowering rate of over 40 %.Treating with combination of gibberellin plus low temperature and gibberellin plus high temperature and illumination significantly increased the flowering rate.The best effect of treatment in growing and flowering was GA_3 high temperature 30 days illumination.In the Summer,no correlation was observed between seedling rate and GA_3 treatments,but dormant bulbs did not flower without GA_3,when treated with GA_3,bulbs flowered 100%.In addition,flower yield varied with treating temperature,the highest yield was from low temperature GA_3.
