Hormone treatment method for improving germination rate and shortening after-ripening period of panax notoginseng seeds

Abstract

The invention provides a hormone treatment method for improving a germination rate and shortening the after-ripening period of panax notoginseng seeds. The method comprises the following steps: selecting 3-year-old mature and full panax notoginseng seeds, artificially peeling, washing with clean water, soaking and disinfecting with a 5% CuSO4 sterilization solution, washing twice, and drying in the shade indoors so as to obtain clean seeds; soaking the clean seeds with a gibberellins (GA3) solution having a mass fraction of 500mg / L, soaking the seeds and the soaking solution for 24 hours according to a ratio of 1:(3-4), flushing with the clean water twice, and airing indoors to obtain clean seeds; and uniformly mixing the clean seeds with wet sand, placing the mixture into a well-ventilated mesh basket, and preserving in a sand deposition room in a shaded condition at the temperature of 4-15 DEG C for 50-60 days. One part of seeds soaked with the 500mg / L of GA3 have cracked seed coatswithin 40 days, and the seeds start to germinate; and the embryo rate reaches 80.7+ / -7.6% within 60 days, and the embryo rate is obviously higher than 63.6+ / -7.5% in a control group subjected to soaking treatment with clean water. According to the method disclosed by the invention, the germination rate of the panax notoginseng seeds can be obviously increased, dormancy can be broken in advance, and the after-ripening period is shortened.

Description

technical field [0001] The invention relates to the technical field of modern Chinese herbal medicine cultivation, in particular to a hormone treatment method for increasing the germination rate of Panax notoginseng seeds and shortening the post-ripening period. Background technique [0002] Sanqi (Panax notoginseng (Burk.) F.H.Chen) is a perennial herb of the Araliaceae family (Araliaceae). , has the effect of hemostasis, anti-heart, brain, liver ischemia, treatment of coronary heart disease, anti-inflammatory, detoxification, and lowering blood sugar and blood lipids. [0003] Panax notoginseng is one of the most distinctive varieties of Chinese medicinal materials in Yunnan Province. The original production area is Wenshan Prefecture and its surrounding areas in Yunnan Province. The planting area and output of Panax notoginseng in Yunnan Province account for more than 95% of the country's total. At present, the most widely used and effective propagation method of Panax n...
