Loquat unisexual fruiting induction agent and its use method

Abstract

A parthenocarpy inducing agent of loquat tree for bearing the non-kernel loquat fruit is prepared proportionally from gibberellin (GA3) and 1-(2-Cl-4-pyridyl)-3-phenylurea (CPPU) through mixing and dissolving it in water. Its application features that it is used to treat the flower buds, flower, or fruit every 29+ / -4 days before fertilization.

Description

Technical field: [0001] The invention relates to a technique for inducing fruiting of loquat fruit. Background technique: [0002] After fertilization, loquat flowers begin to bear fruit and form fruit containing seeds. This is a normal phenomenon, but in some cases, it can also produce fruit without fertilization and form seedless loquat fruit. This is the phenomenon of parthenocarpy of loquat. Loquat parthenocarpy is related to the concentration of auxin contained in the ovary to a certain extent, so similar auxin is used in agriculture to cause parthenocarpy and form seedless loquat. After the exogenous plant growth hormone penetrates into the plant body in a certain way, it will affect the level and mutual balance of endogenous hormones in different ways. Moreover, exogenous plant hormones often have a wide spectrum of action, that is, the same agent may produce different reactions or even opposite results due to different use periods, concentrations, and methods. There...

Problems solved by technology

[0004] 2. The quality of the fruit is not ideal, the content of soluble solids is reduced, the taste is sour, and the taste is not good

[0005] 3. Severe physiological diseases such as sunburn and fruit cracking

[0006] 4. Unable to overcome the variety characteristics of GA on the seedless rate of loquat, and the seedless rate is unstable

[0007] 5. Seedless fruits treated with GA tend to drop fruit at the early stage of development and before and after the fruit color change period, and the yield is low

[0008] 6. Delayed maturity
