Problems solved by technology

However, in the breeding process of water lilies, due to the abnormal germination of pollen on the stigma after pollination, breeders often encounter the phenomenon that water lily selfing can not obtain seeds or few seeds, which makes it difficult for selfing groups of many varieties to obtain

Embodiment

[0014] The present embodiment adopts water lily variety 'Colorado' (purchased in Nanjing Art Lotus Garden Flower Co., Ltd.) to carry out the method for improving the selfing seed setting rate:

[0015] Step 1. On the day before the flowers in Colorado open, use a transparent plastic bag with some small holes for ventilation to isolate the different inflorescences on Colorado;

[0016] Step 2: Pollination is carried out on the morning of the flowering day of the female parent. When the female parent is open on the first day, there is stigma liquid on the stigma plate, and the inflorescence (together with bagging) of the male parent that is opened the next day is taken, and the female parent inflorescence is taken off. After bagging, take more than 5 stamens of the male parent with tweezers and put them into the honey liquid of the stigma plate of the female parent's pistil, stir the powder slightly to scatter, and then add 2ml treatment solution in the stigma plate, the concentr...

Abstract

The invention relates to a water lily selfing method, in particular to a method capable of improving selfing and fruiting rate of the water lily, and belongs to the technical field of plant breeding. The method utilizes chemical reagent to process stigma to improve the biochemical environment the germination environment of the pollen on the stigma, so as to overcome the water lily selfing barrier. The method has the advantages that 1, the method is scientific and reasonable, the sodium chloride and boric acid are adopted to process pistil through spray, so as to influence the material that promotes the pollen tube growth, and accordingly, the germination and continuous growth of the pollen tube are facilitated; 2, the effect is obvious, through overcoming the selfing barrier, the selfing and fruiting rate of the water lily is improved, and the selfing and fruiting of the water lily is better realized, homozygous water lily heredity crowd can be obtained through the selfing method. Due to the adoption of the method, the new water lily variety having good cultivation ornamental performance is possible, and finally, the water lily cultivation range is enlarged, and the purposes of environment protection and peasant income increasing are realized.

Description

technical field [0001] The invention relates to a method for selfing water lilies, in particular to a method for improving the selfing seed setting rate of water lilies, and belongs to the technical field of plant breeding. Background technique [0002] Water lily is a general term for plants of the genus Nymphaea in the family Nymphaeaceae. Water lilies are deeply loved by people for their rich colors, holy implication, and strong adsorption capacity of stems and leaves to nutrient and harmful substances in water, and are widely used in garden waterscapes. However, in the breeding process of water lilies, due to the abnormal germination of pollen on the stigma after pollination, breeders often encounter the phenomenon that water lily selfing can not obtain seeds or few seeds, which makes it difficult to obtain selfing populations of many varieties. In other plants, the use of chemical reagents to treat the stigma of the female parent to overcome selfing barriers has been w...
