Embodiment

[0025] (1) Experimental method

[0026] (1) Tobacco seeds to be tested: The variety to be tested is China Tobacco 201 first-class fine variety, provided by Qingdao China Tobacco Seed Co., Ltd.

[0027] (2) Culture medium setting for germination treatment: gibberellin (GA 3 ) set four concentration gradients of 0, 100mg / L, 300mg / L, and 500mg / L; naphthaleneacetic acid (NAA) set six concentrations of 0, 2mg / L, 5mg / L, 10mg / L, 20mg / L, and 50mg / L Gradient; basic medium is H 2 O, MS liquid medium (Murashige and Skoog, 1962), three factors were completely random combination, 48 treatments, three repetitions.

[0028] (3) Accelerating germination: The seeds are first sterilized with 0.5% copper sulfate solution by weight for 15 minutes, then rinsed several times with distilled water, dried at 30°C to a water content of about 10%, and then accelerated germination with the above prepared culture solution. The germination is carried out in the germination tank, and the air compressor i...

Abstract

The invention belongs to the technical field of germination accelerating treatment and specifically relates to a complete nutrition formula germination accelerating method for tobacco seeds. The method comprises the following steps: putting tobacco seeds in a nutrient solution of MS+100 mg / L gibberellin + 2 mg / L naphthylacetic acid and accelerating germination for 42-46 h under conditions of a temperature of 26-28 DEG C, 12 h illumination / 12 h dark and continuous air feeding for oxygen supplementation; taking the seeds out of a germination accelerating pot, when most of the seeds have broken seed coats, and drying; carrying out coating and pelleting according to a routine technology to obtain the required germination accelerating-type pelleted tobacco seed. The germination accelerating-type pelleted tobacco seed prepared by the invention has advantages of high seed activity, fast sprouting, high rate of emergence and high uniformity, etc.

Description

technical field [0001] The invention belongs to the technical field of seed germination treatment, and in particular relates to a method for accelerating germination of tobacco seeds with a complete nutritional formula. Background technique [0002] Tobacco seeds are an important basis for tobacco leaf production. Studies have shown that pre-sowing pretreatment can significantly improve the vigor of seeds, make seedlings emerge neatly after sowing, and seedlings are strong. Acceleration is one of the simple and effective pre-sowing pre-treatment methods, which can improve the emergence rate and consistency of seeds. At present, water and gibberellin solution are mainly used to accelerate germination of tobacco seeds in production. In the process of seed germination and seedling growth, in addition to the need for suitable light, temperature, and water, plant growth regulators such as naphthaleneacetic acid, macronutrients, and micronutrients all play an important role. But...
