太田等人曾报导过在水稻出穗期喷洒3—羟基—5—甲基异噁唑(日商品名为,中译名通常为立枯灵,以下统称立枯灵—译者)能使低温条件(白天20℃一夜间13℃)下栽培的水稻增加结实率和穗重。太田为了再一次确认立枯灵促进成熟度的效果继继进行实验,指出其效果表现在2次枝梗(所谓弱势颖花)上的此在一次枝梗上的更大些,另一方面,在东日本各地的农业试验场,以太田等人的报告做为基础进行了效果签定试验。通过调查成熟期可以看出,促进灌浆的是1980～1981年进行的31例试验中的13例,剩余的18例没有明显的效果,所以对立枯灵效果没能得出一致的结论。本报告明确指出立枯灵呈然能促进受精后粒重增加的速度,但不增加最终粒重。
Ota et al. Have reported that the spraying of 3-hydroxy-5-methylisoxazole at the heading stage of rice (which is commercially available under the trade name of Ligelnin, hereinafter referred to as Liquingling) (20 ℃ during the day and 13 ℃ overnight) cultivated rice increased seed setting rate and panicle weight. Ota in order to once again confirm the effect of legislation to promote the maturity of the effect of maturity experiments, pointed out that the effect is manifested in the second branch (the so-called disadvantaged spikes) on a branch larger, on the other hand, In the East Japan all over the agricultural test site, the report of the ether and others as a basis for the effectiveness of the test. Through the investigation of maturity, it can be seen that in grouting promotion, 13 of the 31 trials conducted between 1980 and 1981, the remaining 18 cases had no obvious effect, so the antagonistic effect on the antagonistic effects did not reach a consistent conclusion. This report clearly states that liguiling can actually increase the rate of grain weight gain after fertilization without increasing the final grain weight.
