The different application of plant growth regulating technology on Different Crop have nothing in common with each other, and the plant exogenous hormone all has application melon on the various crop such as fruit tree kind.There is research data to show that ethrel, gibberellin, chlormequat, 1-amino-cyclopropane-hormone types variable concentrations such as 1-carboxylic acid have in various degree influence to the melon Sex Differentiation of different growing stage.GA3 (gibberellin) has obviously short female effect in balsam pear, but GA
4(gibberellin) does not also appear in the newspapers to the influence of balsam pear Sex Differentiation; Table rape rope lactone has tangible influence to the growth and the output of cucumber and watermelon, but it is not clear to the influence of balsam pear Sex Differentiation.Also be no lack of application example on fruit tree, find as handling the back at the lichee flower bud differentiation period with ethrel, most of in the flower fringe is that male flower in centre of a small ear unit becomes female flower with 7, illustrate that ethrel has to press down the male female effect of urging, and induces female flower development.(Lei Xintao etc. such as Lei Xintao, Chinese chestnut endogenous hormones and flower Sex Differentiation, fruit tree journal 2002, studies show that 19 (1) .19 pages or leaves-23 page) Chinese chestnut is in physiological differentiation stage, the mensuration of young tip idiophase and female flower idiophase endogenous hormones shows before the winter: the position that forms female flower is easily keeping higher ZR, GA level and lower IAA, ABA level.Comprehensive existing literature search does not find that plant growth regulator had report, the effect of different exogenous hormones to remain further to be familiar with to its male and female flowering differentiation on Jatropha curcas.
For this reason, be badly in need of researching and proposing a Jatropha curcas floral organ than simple, the effective method regulated, to improve fruit-setting rate and seed production.The inventor has proposed this inventive method by for many years Jatropha curcas male and female flowering ratio chemical regulation technique being explored, studied in Yunnan, summing up.Use this inventive method, can make Jatropha curcas male and female flowering behind the field planting 2-3 than improving 10-20%.
