The maximum survival percentage, plant height （cm）, root length （era）, numbers of roots and root weight per cutting were significantly higher in hard wood cuttings. IBA concentration had no speculative effect on plane tree cuttings. Thus, hard wood cutting was the best choice for plan tree propagation.展开更多
通过使用不同浓度3-吲哚丁酸(IBA)处理插条对香花油茶(C.osmantha Ye CX,Ma JL et Ye H)全光照歇喷雾扦插方法进行了研究。结果表明:用浓度高于1 000 mg/L的IBA速蘸处理香花油茶插条能有效的促进插条生根,当浓度在1 500～3 000 mg/L生...通过使用不同浓度3-吲哚丁酸(IBA)处理插条对香花油茶(C.osmantha Ye CX,Ma JL et Ye H)全光照歇喷雾扦插方法进行了研究。结果表明:用浓度高于1 000 mg/L的IBA速蘸处理香花油茶插条能有效的促进插条生根,当浓度在1 500～3 000 mg/L生根率较高,超过90%。生产上香花油茶全光照间歇喷雾扦插繁殖IBA的使用以1 500 mg/L速蘸10 s为宜。展开更多
Plant growth and morphogenesis depend on the levels and distribution of the plant hormone auxin. Plants tightly regulate cellular levels of the active auxin indole-3-acetic acid （IAA） through synthesis, inactivation...Plant growth and morphogenesis depend on the levels and distribution of the plant hormone auxin. Plants tightly regulate cellular levels of the active auxin indole-3-acetic acid （IAA） through synthesis, inactivation, and transport. Although the transporters that move IAA into and out of cells are well characterized and play important roles in devel- opment, little is known about the transport of IAA precursors. In this review, we discuss the accumulating evidence sug- gesting that the IAA precursor indole-3-butyric acid （IBA） is transported independently of the characterized IAA transport machinery along with the recent identification of specific IBA efflux carriers and enzymes suggested to metabolize IBA. These studies have revealed important roles for IBA in maintaining IAA levels and distribution within the plant to support normal development.展开更多
