Effect of Guoguang Rooting Powder on Growth of Superior Seedless Grape Cutting Seedling
摘要
Abstract
In order to improve cutting technology and provide seedling guidance for production of Superior Seedless,effect of different mass concentration of the Guoguang rooting powder on callus induction,rooting rate,germination rate,cutting survival rate and new shoot growth potential of Superior Seedless grape cutting were studied. The results showed that 15 d later the cutting came to grow, and the cutting germination rate of CK was up to 60%. When the Guoguang rooting powder's mass concentration was 2. 5 g/L and 3. 7 g/L,the cutting germination rate was 35%. Different mass concentration of the Guoguang rooting powder could inhibit germination rate of cutting significantly (P<0. 01) compared with CK. When the Guoguang rooting powder's mass concentration was 3. 7 g/L,callus induction rate and rooting rate was up to 100% and 40% increasing 35 and 40 percentage points compared with CK. Different mass concentration of the Guoguang rooting pow-der promoted callus induction rate and rooting rate of cutting significantly(P<0. 01) compared with CK. After 75 d the cutting came to grow,with survival rate up to 95% when it was 3. 7 g/L,and the differences reached significant level(P<0. 01) compared with other treatments. Different treatments had no inhibition effect on new branch length and leaf number significantly. The treatment of 3. 7 g/L had minimal inhibition effect on cutting germination and maximal promotion on rooting and survival. It suggested that Superior Seedless grape seedlings were treated with the Guoguang rooting powder of 3. 7 g/L in order to increase cutting survival rate in nursery seedling production.关键词
