【摘要】 把香石竹 (DianthuscaryophyllusL .)采收期分为 4个阶段 ,对不同时期采收的香石竹进行切花寿命比较试验 ,结果表明 :采收期为第三阶段 (外围花瓣 2～ 3片向外倾斜与水平轴成80°角 )的切花寿命最长为 1 2 .8d ,而且与其它阶段采收的比较来看 ,随着时间的推移花径一直持续增加 ,到了第 3.5d时 ,才有下降趋势 .而其它阶段采收的花朵花径到了第 2 .1d有所下降 ,而第四阶段采收的花径到第 2 .1d时已有萎蔫现象出现 .更多还原

【Abstract】 This study was carried out to investgate the effects of harvest stage on vaselife of cut dianthes caryophyllus L..Harvest stage was divided into four stages.In the third stage,the vaselife was the longest by 12.8 days compared from another stages,and the periods of the flower diameter increasing was the slowest.In the 3.5th days,it was appeared to decreased.The flower diameter was decreased at 2.1th day in stage four.更多还原
