Treatment method capable of improving emerging ability and cold resistance of camellia oleifera seeds

Abstract

The invention belongs to the technical field of biological treatment of seeds and in particular relates to a treatment method capable of improving emerging ability and cold resistance of camellia oleifera seeds. The method specifically comprises the following steps: (1) placing camellia oleifera seeds into an electric field for performing electric field treatment, immersing the seeds into a seed soaking agent to be soaked, stirring by a stirrer, treating with a filter reagent and taking out the camellia oleifera seeds, wherein the seed soaking agent is prepared from the following raw materials: isoalantolactone, polyethylene glycol and water; and (2) freezing in a freezer, taking out the seeds, frying at a constant temperature, taking out, immersing into a nutritional agent to be soaked, treating with the filter reagent and taking out the camellia oleifera seeds, and performing microwave drying, wherein the nutritional agent is prepared from the following raw materials: fructus piperislongi polysaccharide, erythritol, robinia juice, pueraria flavones, sodium hexametaphosphate, ferrous sulfate and water. According to the method, the camellia oleifera germination rate is effectivelyincreased, the breeding survival rate is improved, the seedling breeding period is shortened, seedling breeding is effectively reduced, accumulation of soluble sugar, soluble proteins and proline incamellia oleifera at a low temperature can be effectively promoted, and the cold resistance is improved.

Description

technical field [0001] The invention belongs to the technical field of seed biological treatment, in particular to a treatment method for improving seedling emergence and cold resistance of camellia oleifera seeds. Background technique [0002] Camellia oleifera is one of the main economic forest tree species in China. It likes warmth and is afraid of cold. It is the most valuable oil tree species in Camellia. It is also known as the world's four major woody edible oil plants together with oil palm, olive and coconut; A disaster that is often encountered in plant cultivation. The freezing in the south in 2008 caused huge losses to many economic crops. Although the plants themselves have certain cold resistance, different plant species and varieties have different cold resistance. The cold resistance of organs is also different; therefore, exploring the physiological mechanism of plant cold resistance is not only of great significance in basic theory, but also has great signi...
