Embodiment 1

[0033] 1. Investigation on flowering period

[0034] Methods: The kiwifruits of jujube soft jujube grown in the open field with the age of more than 5 years were selected for observation. The statistics were started when the female or male flowers were revealed, and 10 healthy standard branches were randomly selected, and the flowering process was observed from 8:00 to 10:00 in the morning every day. In the early flowering period, 5%-25% of the flowers are open, in the full flowering period, more than 25% of the flowers are open, and in the last flowering period, more than 50% of the male inflorescences are removed from the anthers.

[0035]Results: The flower buds of Ruanjujuba kiwifruit were mixed buds, which were physiologically differentiated in autumn and morphologically differentiated after budding in the following spring. Plants are usually dioecious, and the best pollination period for female flowers is 2 days after opening. The fruit is climacteric and has a short s...

Abstract

The invention provides a rapid screening method for pollination male plants in an actinidia arguta orchard and application of the rapid screening method, and relates to the technical field of pollination tree configuration. According to the method, the influence of selection and configuration of pollinizers of the actinidia arguta on fruits is analyzed through methods such as flowering phase investigation, pollen preservation and activity determination and callose fluorescent staining, the orchard is scientifically established around the actinidia arguta, the yield and quality are promoted to be improved, and the method has a great significance in improving the garden management efficiency and improving the yield and quality of the actinidia arguta. And a foundation is laid for high-efficiency and standardized cultivation of actinidia arguta. The invention provides a rapid pollination male plant screening technology based on callose fluorescent staining, and scientific and reasonable configuration of pollinizers is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pollination tree configuration, and in particular relates to a rapid screening method for pollinating male plants in a kiwifruit orchard and application thereof. Background technique [0002] In the practice of cultivation and research of kiwifruit, the configuration of pollination trees is the basic means to obtain high quality and high yield. At present, when the pollination tree is configured in the kiwifruit, there is a big blindness, and the pollination tree is often configured at will, and there is no systematic and scientific method for the selection of pollination trees. From the morphological point of view, the flower type of the genus Actinidia is complete flower, but most species are functional dioecious. Due to its special genetic background, the offspring often have more males than females, and even monoecious plants have pollen. Inactive and fruitless condition from (hybrid)cross. Therefor...
