多倍性芒果品种的珠心实生苗,由于它们在遗传上的一致性,因而有利于童期和开花的生理学研究。对于这种芒果实生苗按不同年龄分组进行的研究表明,用1000PPm 以上的乙烯利能诱导顶茅开花;用4000PPm 乙烯利处理实生苗,还观察到大量的老茎开花现象。这种情况说明乙烯利有诱导芒果开花的能力。当我们以1000PPm 赤霉酸和1000PPm 乙烯利混合使用时,发现赤霉酸对乙烯利的诱花效应有拮抗作用。在11—12月芒果花芽自然形成时期,使用1000PPm 赤霉酸后,同样也能抑制成年实生树的开花,相反,同龄的对照植株却大量开花。这就说明了内生赤霉酸可能是芒果童期长,以及成年树不开花的天然因素。
Multiploid mango seedlings of nucellus seedlings, due to their genetic identity, are favorable for the physiology of childhood and flowering. A study of the mango seedlings grouped by age showed that flowering of flowering tops was induced with more than 1000 ppm of ethephon and flowering of a large number of old stems was also treated with 4000 ppm of ethephon. This shows that ethephon has the ability to induce mango flowering. When we use 1000PPm gibberellic acid and 1000PPm ethephon mixed use, we found that gibberellic acid on ethephon induced effect of antagonistic antagonism. During the natural formation of mango flower buds from November to December, the use of 1000 PPM gibberellic acid also inhibited the flowering of mature adult trees. On the contrary, the same age control plants bloomed in large numbers. This shows that endogenous gibberellic acid may be a long-term mango childhood, and adult trees are not natural factors of flowering.
