曾对三个栽培品种的种苗分别用乙烯利(以下称CEPA)5×12~2微克/毫升和5×10~3微克/毫升两种剂量加以处理,研究其对蔗芽萌发、分蘖和幼苗早期生长特性的影响。获知在5×10~3微克/毫升剂量处理下,取自蔗茎上段(梢部)及下段(基部)蔗芽的萌发率均低,下段芽的最终萌芽数更少。但是5×10~3微克/毫升剂量除UCW 5456品种外,却能刺激B4362及HJ5741两品种分蘖的发育。在5×10~2微克/毫升剂量下未见对蔗芽的萌发及分蘖发生作用。萌芽后七周,所有经药剂
The seedlings of three cultivars were treated with ethephon (hereinafter referred to as CEPA) 5 × 12 ~ 2 μg / ml and 5 × 10 ~ 3 μg / ml respectively to study their effects on the germination, tillering and Effect of early seedling growth characteristics. It was found that the germination rate of sugarcane from the upper (shoot) and lower (basal) cane stems was lower at the dose of 5 × 10-3 μg / ml, and the number of final germination of lower segment buds was less. However, except for UCW 5456, the dose of 5 × 10-3 μg / ml stimulated tillering development of both B4362 and HJ5741. No effect was observed on the germination and tillering of sugarcane at the dose of 5 × 10 ~ 2 μg / ml. Seven weeks after germination, all through the agent
