Method for breaking dormancy of new celery seeds

Abstract

The invention discloses a method for breaking the dormancy of new celery seeds. The new celery seeds with remarkable dormancy are used as materials. The method comprises the steps of selecting seeds, soaking the seeds in a 0.08 percent chitosan solution, performing low-temperature treatment on the seeds for at least 6 days under the condition of 5 DEG C, accelerating germination of the seeds under the condition of 20 DEG C after an expected effect is achieved, determining the germination power on the 10th day, and calculating the germination rate on the 21st day. According to the method, the dormancy of the new celery seeds can be effectively broken, and the germination rate is promoted to be remarkably increased, so that the quality of celery seeds can reach national standards, and the timely seed sowing and production of planters are ensured; the method has the characteristics of simple required conditions, convenience in operation, easiness in mastering, low cost, environment friendliness and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting and relates to a method for breaking dormancy of new celery seeds. Background technique [0002] Celery is a biennial vegetable of the genus Celery in the Umbelliferae family. It is rich in nutrients, has a crisp and tender taste, and a refreshing fragrance. It also has pharmacological effects such as reducing blood pressure, reducing fat, and calming pain. reader's favorite. There are celery plantings in all parts of the north and south of my country. The sowing area is large, the crop times are many, and the annual production requires a large amount of celery varieties every year. Celery seeds are very small, with a thousand-grain weight of only about 0.41 grams, leathery skin, poor water permeability, and slow and irregular germination (Jin Lizheng et al., Anhui Agricultural Science, Issue 20, 2009), especially when the newly harvested celery seeds germinate The germination rate is...

Problems solved by technology

Obviously, this affected the quality inspection and timely sales of commercial seeds that year, and also brought troubles to growers.

[0003] In order to break the dormancy of celery seeds and improve the germination ability, some people have used gibberellin (Thomas, Plant Growth Regulation, No. 8, 1989), potassium nitrate (Zhao Meihua et al. , Shanxi Agricultural Science, No. 3, 2000), PEG (Fan Xinmin et al., Journal of Shihezi University, No. 1, 2006), naphthaleneacetic acid (Li Dongxia, Modern Agricultural Science and Technology, No. 8, 2008) and other agents for soaking treatment, There are also people who utilize low temperature (Finch, Scientia Horticulturae, No. 16 of 1982), variable temperature (Liu Yan, etc., Anhui Agricultural Science, No. 6 of 2008) or freezing (Zhuang Tianming, etc., CN101213897A) to pretreat celery seeds , most of these methods can receive certain effects, but there are deficiencies at the same time: the one, the medicaments used are mostly chemical synthetic substances, which is not conducive to the pollution-free production of celery; During the germination period, the surface of the seeds is easy to go moldy, which directly affects the germination results; the third is that most of the materials used in the above research are not newly harvested celery seeds, and their dormancy has been all alleviated, or the nature of their dormancy has not been primary-dormancy (primary-dormancy). ), but thermo-dormancy caused by high temperature, therefore, the effect of the above method cannot be well reproduced on new celery seeds
