不同浓度的跟茂对水仙生长的影响

采用不同浓度的跟茂对水仙植株进行处理,验证跟茂对水仙的作用效果.结果表明:不同浓度的跟茂对水仙株高和花茎高都有较明显的抑制作用,但2 000倍的矮化效果最好,且对根长的生长有明显的促进作用,在高浓度处理中,水仙的花朵直径平均比对照增大0.33 cm,同时花朵数量也明显增加,花期延长了2～5 d.适宜浓度的跟茂可以使水仙植株矮化,花茎缩短,增加花朵数量,花朵变大,株型紧凑,直立平稳,明显提高了水仙的观赏价值.

The Influence of Different Concentrations Genmao on Growth of Narcissi

To increase the charm of narcissi,test the effect of Genmao with different concentrations on narcissi were studied.The results showed that the regulators could inhibit the growths of height and pedicel of narcissi.of the five regulators,the dwarfing effects of 2 000 time solution on narcissi were better,and had significant effect on the root length.and flower diameter increase 0.33 centimeter and also quantity was obvious raise,and the range delayed was from 2 days to 5 days.The concentration analysis results showed that there was a significant correlation between the time of flowering and the concentrations of regulators.The ornament value of narcissi was obviously improved by using the Genmao.
