Problems solved by technology

[0003] Wild iris plants are mainly propagated by ramets, but the reproduction coefficient is low, and they can also be propagated by sowing, but most of the iris seeds have dormancy, and it is difficult to emerge, which brings certain difficulties to the introduction, cultivation and breeding of iris resources. Its application in horticultural cultivation and hybrid breeding

Abstract

The invention discloses a method for promoting seed germination of iris plants. The seed germination rate is greatly increased by soaking the iris seeds with one drug of 6-BA, KNO3 and H2O2 and then seeding; the theoretical guidance is supplied for genetic resources, cross breeding, propagation and garden application of iris plants in China; through detection, 6-BA, KNO3 and H2O2 have an obvious promoting effect to the seed germination of iris lacteal; the effect is obvious; the optimal concentrations are respectively 300mg / L, 0.4% and 0.1%; the germination percentages are respectively 78.89%,90.00% and 86.67%; the 6-BA and H2O2 have an obvious or excellent promoting effect to the seed germination of iris ensata, the optimal concentrations are respectively 200mg / L and 0.4% and the germination percentages are respectively 93.33% and 50.00%.

Description

technical field [0001] The invention relates to the field of plant species, in particular to a method for improving seed germination of plants of the genus Iris. Background technique [0002] The genus Iris is a perennial herbaceous plant with abundant germplasm resources in my country. Because of its wide variety, strong adaptability, large and colorful flowers, and unique flower shapes, it is one of the excellent materials for greening cities. It can also be used for medicine and feed, and has broad prospects in cut flowers and landscaping. [0003] Wild iris plants are mainly propagated by ramets, but the reproduction coefficient is low, and they can also be propagated by sowing, but most of the iris seeds have dormancy, and it is difficult to emerge, which brings certain difficulties to the introduction, cultivation and breeding of iris resources. Its application in horticultural cultivation and hybrid breeding. A large number of scholars have conducted research on its...
