The present experiment was carried out in Hangzhou, Zhejiang du-ring 1983 to 1985, in order to find out the different responses of ethy-lene, ethephon and ACC treatments in relation to different varieties,the site of action and factors affecting the responses.

乙烯利(2-氯乙基磷酸,Ethephon,Ethrel)可以促进瓠瓜(Lagenarialeucantha Rushy)雌花的产生,减少雄花的数目。但过去的试验只用了一个早熟品种,即杭州‘长葫芦’。本试验结果表明,不同品种对乙烯利的反应不同,早熟品种对乙烯利诱导雌花的反应最敏感,中熟品种次之,晚熟品种最迟钝。早熟品种(杭州‘长葫芦’)在幼苗期用150ppm乙烯利处理,可以有效地促进雌花产生,而中熟品种(温州‘圆葫芦’)和晚熟品种(杭州‘牛腿葫芦’),则要分别用200和300ppm才能得到相应的效果。不同品种对乙烯利浓度反应的差异,是与品种间茎尖组织的乙烯含量有关。早熟品种茎尖组织的乙烯释放量较多,而晚熟品种较少。但早熟品种茎尖组织中MAC[1-(丙二酰氨基)环丙烷-1-羧酸,即结合态的ACC]的含量较少,而晚熟品种较多。至于温度对乙烯利诱导多生雌花的效果,则是通过影响乙烯利的分解速率而起作用的。 乙烯利水溶液不论是茎尖喷洒还是叶片喷洒,都可以促进瓠瓜多生雌花。但用乙烯气体处理时,只有当茎尖部分受到处理,才能诱导多生雌花,若仅处理叶部,则没有什么效果。ACC(1-氨基环丙烷-1-羧酸)是乙烯生物合成...

This article gives a detail analysis on the factors which caused the flash explosion in the plastic Factory of The Shanghai General petrochemical plant during static-electricity discharging due to the friction of powder granules in the procedure of high pressure polythylene product transportation in the pipe and its storage in the storing slot. It also shows the measurement results of the granule distribution, the perameters of all kinds of staticelectricity as well as the lower limit for the mixture of dust and ethylene gas to explose in the air. At last, the article comes to a conclusion that all the three flash explosion happened in the storing slot of the hihg pressure workshop of the plastic Factory were caused hy the staticelectricity discharge. The authors hope to prevent the kind of accident by using automatic static-electricity, dust and flamable gas monitor and by adopting some measures to relief and contain the explosion.
