Effects of Storage Condition, and Temperature and Light Condition on the Germination of Seeds of a Few Wild Flower Species

Abstract

A Iaboratory test was made of the germination of the seeds of four wild flower species which are considered important members of the attractive grassland community.
Measurements were conducted on freshly-collected and stored seeds. Responses to storage methods (dry and wet at 3°C), temperature, and light conditions in relationship to germination were examined.
Ixeris stoloniferam The effect of light on germination was not recognized. Germination of seeds with stratification was inhibited, but seeds in dry storage at 3°C maintained their initial germinability. Ixeris dentata Almost no germination was observed in the dark. Germination was accelerated by stratification or under illumination. Seeds showed the best germinability when given both treatments. Picris hieracioids subsp. japonica and Chrysanthemum leucanthemum Good germination was observed not only in the light but also in the dark in these species. Stratification or illumination raised their germinability.
