【摘要】 随着第1腋芽上方留枝长度的延长、第1腋芽的萌发延迟,完成发育所需的时间延长,而现蕾、开花及切花品质影响不大。BA显著促进第1腋芽的萌发,而生长素会抑制其腋芽的萌发,并延长发育所需的总天数,抑制效果以NAA最强,IBA次之,IAA最差。生长素处理影响了月季的顶端优势,在抑制第1腋芽萌发的同时促进了第2腋芽的萌发。更多还原

【Abstract】 After harvest the sprouting of the first bud on the stem was delayed with the increase of the stem section remained above it. The stem section had little effect on bud development, flowering, and cut flower quality. Benzylamino adenine(BA) significantly promoted the sprouting of the first bud, and auxin inhibited it. Among the auxin used, naphthyacetic acid (NAA) showed the most strong inhibition, followed by indolebutyric acid(IBA) and indolacetic acid( IAA). Auxin affected the apical dominance of axillary buds on rose stem, and promoted the sprouting of second bud wth the inhibition of the first bud.更多还原
