Abstract

The invention provides a tobacco seed primer, a preparation method of the tobacco seed primer, and a tobacco seed priming method, and relates to the technical field of plant cultivation. The tobacco seed primer provided herein is made from calcium chloride, gibberellin, betaine, proline, salicylic acid, sodium nitroprusside, and trehalose. The tobacco seed primer is capable of enhancing the resistance of tobacco seeds to low temperature stress, drought stress and low temperature and drought cross-stress, and is effective for increasing emergence rate of tobacco seeds and the quality of seedlings. In addition, the invention provides the preparation method of the tobacco seed primer; by dissolving calcium chloride, gibberellin, proline, salicylic acid, trehalose, betaine, and sodium nitroprusside sequentially in water, it is possible to effectively ensure the priming effect of the primer. In addition, according to the priming method of tobacco seeds provided herein, by using the tobacco seed primer provided herein, it is possible to enhance the cold resistance and drought resistance of tobacco seeds.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a tobacco seed initiator, a preparation method thereof and a tobacco seed initiation method. Background technique [0002] Seed priming belongs to the category of seed treatment technology. Seed priming is to control the slow absorption of water by the seeds so that they stay in the second stage of imbibition, allowing the seeds to perform the physiological and biochemical metabolism and repair of pre-germination, promote the repair of cell membranes, organelles, DNA and the activation of enzymes, and are ready to germinate Metabolic state, but prevents protrusion of radicle. [0003] Seed priming has been successfully applied to many plant species including vegetable crops such as kale, beetroot, cabbage, parsnips, carrots, celery, cucumbers, green onions, cantaloupe, melons, onions, parsley, peas , capsicum, beet, tomato, spinach, and watermelon; food crops such as ...
