Abstract

The invention provides a method for enhancing germination rate of Vitex negundo var.heterophylla Rehd. seeds. The method comprises selecting half-brown wide Vitex negundo var.heterophylla Rehd. seeds gathered from September 10th to September 20th, and braking the seed dormancy to promote seed germination through gibberellin solution treatment method or low-temperature stratification treatment method. The germination rate can reach 46.88% if the Vitex negundo var.heterophylla Rehd. seeds are gathered in the optimum period according to the invention method, and the germination rate reaches as high as 70.83% or 72.22% if the gathered Vitex negundo var.heterophylla Rehd. seeds in the optimum period are further treated by gibberellin solution treatment method or low-temperature stratification treatment method. The seeds have the advantages of germination tidiness, low germination time and strong germination. The method of the invention is low in cost and convenient in operation, which is advantageous for development, utilization and large area popularization of wild Vitex negundo var.heterophylla Rehd.

Description

technical field

[0001] The invention belongs to the technical field of seed germination, and specifically relates to a method for breaking seed dormancy and increasing the germination rate of Vitex twig seeds by using timely harvested wild Vitex twig seeds and treating them with phytohormone gibberellin or layering and accelerating germination. Background technique

[0002] Vitex [Vitex negundo var.heterophylla (Franch.) Rehd.], Verbenaceae Vitex, deciduous shrub, distributed in northeast, north, northwest, central, southwest and other provinces, often grows in shrub communities on sunny slopes of mountains , resistant to barrenness, drought, severe cold, well-developed and densely woven root system, with excellent biological and ecological characteristics, it is an excellent soil and water conservation shrub in my country. According to long-term observation, Vitex twigs grow well in rock crevices with a thickness of only 2cm, and the plant acid secreted by it can promote roc...
