Method for preventing and treating vivipary radicle-caused pulp penetration disease in Keitt mango

Abstract

The invention discloses a method for preventing and treating vivipary radicle-caused pulp penetration disease in Keitt mango. Fruits of Keitt mango are bagged, 1-10 g of activated carbon is arranged in the fruit bags for 60 days, and 1 L of 4% Eupatorium adenophorum leaf extract is injected into main branches of trees. The method helps inhibit the germination of mango seeds in the pulp, the embryogermination rate and the radicle penetrating rate can be obviously reduced, the growth of main radicles can be inhibited, and the fruit quality and commodity fruit rate of mango can be increased.

Description

technical field [0001] The invention relates to the technical field of fruit tree prevention and control, in particular to a method for preventing and treating 'Kate' awn embryo root-piercing disease. Background technique [0002] Fetal germination refers to the germination process of seeds in the fruit. After a period of fetal germination, the main root of the embryo penetrates the seed nucleus and penetrates into the pulp, forming root-piercing disease. Mango seeds are recalcitrant seeds. When the seeds complete cell growth and dry matter accumulation to mature, mature seeds do not need to go through the dehydration process for germination. Mango seeds generally mature earlier than the pulp, and the seeds begin to germinate immediately after ripening in the fruit. Therefore, fetal germination is more common in mango varieties, and root penetration is more common in late-maturing mango producing areas. [0003] 'Kate' mango is a rare late-maturing mango variety with a long...

AI Technical Summary

Problems solved by technology

The soluble solids, ascorbic acid, carotenoids and edibility of the fruit with embryonic root penetration were lower than those of normal fruit, and the total acid content was higher than that of normal fruit. The fruit quality and appearance of 'Kate' mangoes were easily marketable due to the disease of fetal sprouting root penetration reduced, resulting in huge economic losses, seriously restricting the production and development of 'Kate' awn

In the current production, we only have a preliminary understanding of the causes of mango fetal germination. There are physiological reasons for the seed to mature earlier than the pulp, and the germination does not go through the dehydration process. The soil uses too much nitrogen fertilizer, too little calcium fertilizer, and fruit bagging and other cultivation and management reasons. The reasons for the influence of climate at different planting altitudes, but there is no report on the exact method for the prevention and treatment of mango root-piercing disease
