Abstract
Inhibition of forest damage exerts by ultraviolet rays. By selecting species having triploid or tetraploid of chromosomes and afforestating to form the ultraviolet resistant forest by forming the artificial forest.
Claims11
A method of planting trees, comprising the steps of:
- selecting conifer seedlings having a tetraploid chromosome number;
- determining which of the selected conifer seedlings exhibit resistance to ultraviolet rays;
- and
- planting in a forest only the selected seedlings which exhibit resistance to ultraviolet rays.
1 more element
A method of growing plants, comprising the step of:
- artificially forming vegetation which is significantly resistant to ultraviolet rays, as compared with vegetation constituted of diploid plants, by selectively growing plants whose chromosone number is tetraploid and thus exceeds the basic number of the species and which exhibit resistance to ultraviolet rays.
