Effects Of Seaweed Fertilizer And S-ABA In Leaf Photosynthetic And The Coloring Physiological Mechanism Of Fruits Of ’Red Globe’

In this study,the ’Red Globe’ grape (late maturing varieties) has grown 7 years. The experimental treatment are SUNRED1000 times liquid, SUNRED800 times liquid, SUNRED600 times liquid, S-ABA 300 times, S-ABA times liquid, S-ABAt100 times liquid, mixed300 times liquid,200 times liquid and mixed 100 times liquid. Explore the of the Red Globe Grape turn color to the mature stage in the process of photosynthesis, fruit color and quality, coloring content of key enzymes of. The research results are as follows:1、Seaweed fertilizer, S-ABA elements both individually and mixed application spraying, can effectively improve the ’Red Globe’ grape chlorophyll a, chlorophyll b and total chlorophyll content. Seaweed fertilizer SUNRED1000 times promote ’Red Globe’ grape chlorophyll synthesis accumulate the best, the chlorophyll content of 30.04mg/g, followed by S-ABAB 100 times and 200 times a mixture of both.2、Spraying different concentrations of seaweed fertilizer SUNRED and S-ABA can improve the ’Red Globe’ grape leaf net photosynthesis, stomatal conductance and transpiration rate, reducing CO2 concentration vane cell; seaweed fertilizer SUNRED promote ’Red Globe’ grape photosynthesis performance is better than S-ABA. Seaweed fertilizer SUNRED 1000 processing times improve leaf photosynthetic characteristics best.3、Seaweed fertilizer spraying alone and S-ABA can effectively improve the appearance of the quality of ’Red Globe’ grapes, increasing the content of anthocyanin in peel, peel coloring promote and improve the degree of coloring, increased fruit diameter and fruit weight aspect. But both inhibited the synthesis of mixed spraying colored peel and anthocyanins. Seaweed fertilizer to improve the ’Red Globe’ grape appearance quality of the best, to improve processing times SUNRED 1000 anthocyanin content, promote the coloring and increase the fruits of vertical and horizontal diameter and fruit weight the best, followed by S-ABA 100 times.4、Spraying different concentrations of seaweed fertilizer SUNRED and S-ABA can improve the intrinsic quality of ’Red Earth’ fruit, increasing the content of soluble solids, soluble sugar and Vc of. Seaweed fertilizer SUNRED improve the intrinsic quality of the fruit of the best, including seaweed fertilizer SUNRED1000 times of soluble solids, soluble sugar content were the highest, followed by hormone and S-ABA.5-. Seaweed fertilizer spraying alone and S-ABA can improve the ’Red Globe’ grape skins phenylalanine ammonia lyase. chalcone isomerase. dihydrofolate reductase flavonoid flavonol glycoside transfer 3,5 enzymes levels, which SUNRED 1000 best times, followed by S-ABA, mixture treatment effect was not significant.
