Embodiment 1

[0014] physical mutagen 60 Co-γ-ray radiation mutagenic breeding of bentgrass:

[0015] Get 1.0 kilograms of creeping bentgrass dry seeds that moisture content is 13.5% and be starting material, with 60 Co-γ-ray radiation, the treatment dose is 600Gy. One week after radiation treatment, direct mutagenesis of contemporary (M 0 ) seeds, when the mutagenesis generation (M 1 ) seedlings were grown to the 2-3 leaf stage to screen 3 variant strains with leaf edge albinism with the naked eye. Take the above-mentioned mutant strains, and carry out vegetative propagation with twigs or branches. The creeping bentgrass with albino leaf edge after propagation was placed in an artificial light temperature climate chamber to measure the temperature and light sensitivity, and they were planted in Hangzhou, Zhejiang and Lingshui, Hainan to evaluate the expression stability. At the same time, compared with the normal green creeping bentgrass, observing the biological characteristics and b...

Embodiment 2

[0017] The chemical mutagen sodium azide induced mutagenic breeding of silver-edged and golden bermudagrass:

[0018] Get 1.0 kilograms of Bermudagrass dry seeds with a moisture content of 13.5% as starting material, after soaking the seeds in distilled water for 16 hours, process with the chemical mutagen sodium azide, and the dosage of processing is 3.0mMh (concentration of sodium azide 1.0 mM, the treatment time is 3 hours, and the treatment temperature is 25°C). Direct direct mutagenesis (M 0 ) seeds, when the mutagenesis generation (M 1 ) seedlings grow to the 2-3 leaf stage to screen 1 yellow mutant strain and 1 yellow mutant strain with the naked eye, and screen out 1 small branch or branch with albino leaf edge from the normal growing turf . Take the above-mentioned mutant strains, twigs or branches, and reproduce them as vegetative bodies. After breeding, they were placed in an artificial light temperature climate chamber for temperature and light sensitivity meas...

Abstract

A method for breeding the color-leaf lawn grass includes such steps as getting the seeds, mutagenizing, screening the plants with varied leaf color, and vegetative propagating.

Description

technical field [0001] The invention relates to a method for cultivating colorful turfgrass. Background technique [0002] Lawn has multiple functions such as maintaining water and soil, transforming nature, and beautifying the environment. It plays an important role in improving the urban living environment and creating leisure places. Up to now, all can only utilize the single green lawn grass of color in domestic and foreign sports venues and urban afforestation. In real life, various places (together) such as football fields, golf courses, sports fields and celebrations have shown a desire for colorful lawn grasses. Due to the lack of lawn grasses of other colors, in some cases people have to adopt chemically colored grasses painted with chemical dyes. Contents of the invention [0003] The purpose of the present invention is to provide a method for cultivating the coleus turfgrass. [0004] The cultivation method of...
