Effects of two kinds of plant growth regulator on propagation of Curcuma alismatifolia bulbs
摘要
Abstract
[Objective]The present experiment was conducted to investigate the effects of different plant growth regulators on propagation of Curcuma alismatifolia bulbs and to screen and optimize the plant growth regulator for increasing the yield and quality of new bulbs. [Method]Different concentrations (0.25, 0.50, 1.00 mmol/L) of methyl jasmonate (Me—JA) and NAA were used for spraying on the leaves to investigate the effects on the number, weight and size of new bulb and storage roots of Curcuma alismatifolia variety Chiangmai Pink. [Result]The results showed that after spraying different concentrations of Me-JA and NAA, the number of new bulbs was more than that of control, the Me-JA(0.5 mmol/L) treatment recorded the highest bulb number (5.27/plant) and which was higher than the control (3.6/plant). The number and percentage of bulb with diameter ≥ 1.5 cm in different treatments were also higher than that of control. The 0.25 mmol/L NAA treatment recorded highest(232) bulbs which accounted for 84.1%. Furthermore, the percentage of new bulbs with more than 3 roots at 0.25 mmol/L NAA treatment was also the highest (59.4%). [ Conclusion ] Based on the analysis and comparison of results, 0.5 mmol/L Me-JA and 0.25 mmol/L NAA were found to be favorable for propagation of Curcuma atismatifolia bulbs.关键词
