A method for artificial cross pollination of Sapindus chinensis

Abstract

The invention provides an artificial hybridization and pollination method for Chinese soapberry fruits. The artificial hybridization and pollination method includes the steps that hybridization male and female parents are selected; male parent pollen is collected and stored; female parent inflorescence is sleeved with a bag, and castration is conducted; pollination is conducted on the female parent in the best pollination period; female parent inflorescence is then sleeved with sulfuric acid paper bags after pollination is conducted, and the fruit development process is observed. By means of the artificial hybridization and pollination method, effective pollination of the Chinese soapberry fruits can be guaranteed, contamination to other pollen is avoided, the problem of existing Chinese soapberry fruits that abscission of fruits is caused due to poor pollination and fertilization is solved, the initial fruit setting rate is raised, hybridization of the Chinese soapberry fruits is achieved, the problem of hybridization of the Chinese soapberry fruits is broken through, quality of the fruits is improved, and the method is low in cost and easy to implement in the application process.

Description

technical field

[0001] The invention relates to a method for pollination of biomass energy tree species, in particular to a method for artificial cross-pollination of Sapindus sapinstrils. Background technique

[0002] Today, when non-renewable energy sources are increasingly depleted, the development of biomass energy is of great significance to the sustainable development of the national economy, national security and social progress. The oil content of Sapindus mukorossi seeds is as high as 40.7%, and the oil has good oxidation stability. The oleic acid and linoleic acid in the oil squeezed from the whole fruit are as high as 62.5%, of which C16-C20 fatty acids account for 98.2%. All meet the requirements of biomass raw material oil; in addition, Sapindus pericarp is rich in saponin and has various biological activities, and can be used as daily chemical products and drug research. Sapindus is widely distributed in southern my country, and it is an ideal tree species for...

[0027] A method for artificial cross-pollination of Sapindus chinensis, comprising the following steps:

[0028] (1) Select hybrid parents;

[0029] Select a single plant with stable and high yield, healthy growth, excellent fruit economic traits, moderate number of inflorescences in the current year, and relatively consistent phenological period as the parental parent. The flowering period of the male parent is required to be marked earlier than that of the female parent, and the flowering dynamics of the parental parent should be observed every day. It can ensure that there is no influence of large or small annual output on pollination results, and at the same time, it can also ensure that the selected tree fruit grows with sufficient nutrition supply.

[0030] (2) Collection and storage of male parent pollen:

[0031] Collect the inflorescences when the infertile flowers of the male parent are about to open, select the florets of the day before flowering and the day of flo...
