Abstract

The invention discloses a method for increasing seed germination rate of evening primrose. Technologies for breaking seed dormancy like radiation and soaking are comprehensively utilized. Seed seedlings of evening primrose obtained by utilizing the method are developed in root system, good in growing trend and high in speed, and seed germination rate and survival rate are increased.

Description

technical field [0001] The invention relates to the technical field of seed treatment methods, in particular to a method for improving the germination rate of evening primrose seeds. Background technique [0002] Evening primrose is an erect, 2a-growing herbaceous plant of the genus Evening Primrose in the Willowleafaceae family, with a stem height of 50-200cm, unbranched or branched; the basal leaves are oblanceolate, and the cauline leaves are oval to oblanceolate ; The flowering period is from May to August, and the fruiting period is from August to November. There are many varieties of flowers, bright colors, yellow, golden, white or light red, fragrant, suitable for forest edge planting in parks, green spaces and roadside greening, and can also be potted. At the same time, evening primrose also has extremely high medicinal value, which has the effects of nourishing blood vessels, lowering blood lipids, and strengthening the body and brain. At present, the academic com...
