Problems solved by technology

The main reasons for the dormancy of the seeds of Chonglou are germination inhibitors, incomplete embryo development, and physiological after-ripening. Combined with previous studies, it has been found that the seeds can complete morphological after-ripening after high-temperature stratification treatment, but the seeds still need to be matured. The hypocotyl growth can only be promoted through physiological post-ripening once in low-temperature stratification, which indicates that the early stage of germination of P. chinensis seeds is limited by morphological post-ripening, and the germination of seeds after morphological maturity is limited by physiological post-ripening

Embodiment Construction

[0015] The preferred embodiment of the method for breaking the dormancy of Dabie Mountain wild Pachyphytum seeds of the present invention will be described in detail below.

[0016] The method for breaking the dormancy of the Dabie Mountain wild polyphylla seeds comprises the following steps:

[0017] (1) Seed coat treatment and sterilization: The outer testa must be removed. You can first soak it in warm water at 25°C for 24 hours, then mix fresh seeds with wet sand, rub off the red outer testa, and sterilize the seeds with 75% Soak in ethanol for 1 to 2 minutes, then sterilize with 0.2% mercury liter for 15 minutes, add 50% carbendazim during the layering process to keep it sterile for a long time, and sterilize the sand with high-temperature steam above 100°C; There is a water absorption barrier, and the outer seeds do not have germination-inhibiting substances, but the germination-inhibiting substances are prevented from being discharged, and the outer seed coat must be tr...

Abstract

The invention discloses a method for breaking dormancy of wild paris polyphylla seeds in the Dabie Mountain and relates to the field of traditional Chinese medicine cultivation. According to the method for breaking dormancy of the wild paris polyphylla seeds in the Dabie Mountain, seed coat treatment and sterilization and step-by-step seed dormancy breaking are adopted, and the lamination treatment time is short and is shortened from original 18 months to 6 months. By means of the method, the problem about time cost for planting of paris polyphylla by traditional Chinese medicine material planting farmers is solved. The germination rate is high and reaches 95% or above after the paris polyphylla seeds are treated with the method as compared with the low seed germination rate of 50% or below with an original treatment method.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine cultivation, and more specifically, the invention relates to a method for breaking dormancy of wild Pachyphytum seeds in Dabie Mountains. Background technique [0002] The degree of dormancy is high, the germination rate is slow, and the germination rate is low. It takes 18 months to complete the dormancy cycle. The key purpose of the present invention is to shorten the dormancy time. The main reasons for the dormancy of the seeds of Chonglou are germination inhibitors, incomplete embryo development, and physiological after-ripening. Combined with previous studies, it has been found that the seeds can complete morphological after-ripening after high-temperature stratification treatment, but the seeds still need to be matured. The growth of hypocotyls can only be promoted through physiological after-ripening after one low-temperature stratification, which indicates that the pre-germinati...
