The effect of extraneous GA3,6-BA on the flowering rate,the number of flower,the flowering time,and flowering qulity of two nobile-type Dendrobium,D.Corona×（D.Malones×D.Love）（D1）and D.Red Emperor×D....The effect of extraneous GA3,6-BA on the flowering rate,the number of flower,the flowering time,and flowering qulity of two nobile-type Dendrobium,D.Corona×（D.Malones×D.Love）（D1）and D.Red Emperor×D.Love Hunter（D2）,were tested.The results indicated that the concentration and kind of used hormone had different effect on the hybrids.D1 should be treated in 25 mg·L-1 GA3 and 800 mg·L-1 6-BA,which promotes the flowering and the quality of flower.But D2 should be treated in 10 mg·L-1 GA3 and 800 mg·L-1 6-BA.展开更多
