Problems solved by technology

In the early stage (Chinese patent application CN2021105706548, a method for inducing fruiting of delicious kiwifruit male flowers), our team successfully screened out the optimal concentration to promote delicious kiwifruit male flower fruit setting by using different concentrations of CPPU on the ovary of delicious kiwifruit male flowers. Other types of kiwifruit (such as maohua, Lingui, bar leaf, red stem, soft jujube, calyx, Gezao, etc.) are not suitable for the induction of male flower ovary, which may be affected by species characteristics, developmental period, External environmental conditions and other factors

Abstract

The invention relates to a method for inducing different types of kiwi fruit male flowers to bear fruits, which comprises the following steps: 2-3 days before the kiwi fruit male flowers bloom, treating internal ovaries of male flower buds by using an inducer; the inducer is a mixed solution of 1-(2-chloro-4-pyridyl)-3-phenylurea and a growth regulator, and the inducer is a mixed solution of 1-(2-chloro-4-pyridyl)-3- The growth regulator is one or a mixture of more than two of indolebutyric acid, thiadiazole phenylurea, gibberellic acid and 2, 4-dichlorphenoxyacetic acid. In the inducer, the concentration of the 1-(2-chloro-4-pyridyl)-3-phenylurea is 120 to 140 mg/L, and the concentration of the growth regulator is 0.2 to 0.4 g/L. The method has important application value for understanding related characters of kiwi fruit male plant fruits, carrying out male resource type identification, improving the purposiveness of male plant selection in the intraspecific or interspecific cross breeding process and accelerating the kiwi fruit cross breeding process.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for inducing the development of aborted ovaries of male flowers, in particular to a method for inducing different types of kiwifruit (including Maohua, Delicious, Lingui, striped leaves, red stems, soft jujube, calyx, Gezao, etc.) method of male flower ovary fruit setting. Background technique [0002] Actinidia is a perennial deciduous vine of the Actiniaceae family, and there are 54 species, 21 varieties, and about 75 taxa in this genus. China is the origin of the kiwifruit genus. From the cold temperate zone in the north to the equator in the south, there is an extremely rich distribution of kiwifruit resources. The fruits of the vast majority of kiwifruit species are edible, and the types currently used in production are mainly Chinese kiwifruit varieties, delicious kiwifruit varieties, and a small amount of soft jujube kiwifruit and hairy kiwi...
