Horseradish plantlet culture method

Abstract

The invention discloses a horseradish plantlet culture method which comprises the steps of (A) rootage cultivation: transferring sterilized and detoxified stem tip meristem after primary culture into a 1 / 2 MS culture medium which is free from hormone for growing; (B) transplanting and hardening plantlet: after keeping the step (A) for 28-32d, transplanting into a potted tray; and (C) planting in field: after transplanting and hardening the plantlet in the step (B) for 75-85d, transplanting the product horseradish plantlet into a field. According to the horseradish plantlet culture method disclosed by the invention, a rootage agent is added into the culture medium for the propagation culture to replace cytokinin, so that the problems of comparatively slow rootage and slender root are solved, and a purpose of rapidly lengthening the root of a single seedling is achieved in a short period; meanwhile, the rootage agent is farther lower than the cytokinin in price, and is lower in dosage and higher in utilization rate, and in comparison with the auxin culture way which is comparatively serious in waste of the auxin and low in utilization rate, the culture method greatly reduces the cost.

Description

technical field [0001] The invention relates to a method for cultivating seedlings in the field of agriculture, in particular to a method for cultivating wasabi seedlings. Background technique [0002] In the development of wasabi industry in our country, ink disease (also known as black heart disease) is the most important disease of wasabi planting, which can cause complete failure of wasabi planting in severe cases. Existing studies have found that squirrel disease is a specific disease of wasabi, which does not cause harm to other crops and does not cause adverse effects on human health. Ink disease is caused by the fungus Phoma wasabiae Yokogi invading wasabi plants and infecting wasabi plants mainly through vascular bundle conduction, which seriously affects the quality and yield of wasabi, and even leads to the failure of wasabi harvest. Ink disease can damage the rhizomes, fibrous roots, leaves, and petioles of wasabi. After many years of research in Japan, Taiwan,...

Problems solved by technology

[0005] It can be seen from the above that the traditional seedling breeding method leads to low seedling reproduction coefficient and slow propagation speed, making it difficult to produce a large number of high-quality healthy seedlings
