STUDY ON THE EFFECTS OF SEED PROCESSING TIME AND SEEDING TIME ON RATING RATIO AND QUALITY OF BACHATIN PLANTS ONLY AT BAT XAT DISTRICT, LAO CAI

Abstract

Research on propagation techniques will enhance the germination rate and seedling rate when out nersery, creating seedlings of uniformity and high quality. Research experiments on processing time and seeding season of Angelica dahurica Benth. et Hook were conducted. Experimental of processing time consists of 5 formulas and season experiments include 6 formulas. Research results show that the processing time have germination rate and seedlings rate are high standard of out nersery is soaking seeds with warm water for 4 hours. The appropriate season for seeding of Angelica dahurica Benth. et Hook is the October of the every year.
