Effects of plant hormones and lactic acid bacteria on the growth of Ginkgo biloba L.leaves
In order to explore the biological fertilization formula for growth regulation of Ginkgo biloba leaves,gibberellin,cytokinin and trace elements were applied with lactic acid bacteria solution to study the effects of these two plant hormones,trace elements and microbial fertilizers on the growth of Ginkgo biloba leaves.The results showed that 4％boron and 4％gibberellin treatment had the best effect on delaying the leaf withering,increasing the length and width of leaves,and reducing the fruiting yield of Ginkgo biloba,followed by 8％manganese and 4％gibberellin treatments.After the treatment of trace elements of 4％boron+8％manganese and 4％gibberellin,the defoliation time of Ginkgo biloba was delayed for more than a week,and the fruiting yield of Ginkgo biloba was reduced by 24.96％.In addition,it was found that the combination of 4％boron+8％manganese,4％gibberellin and lactic acid bacteria solution and the use of hydroxy propyl methyl cellulose(HPMC)membrane for pollination isolation had the most significant effect on the growth of Ginkgo biloba leaves.
