The invention provides a method for increasing the
seedling forming rate of grape seeds. The method comprises the steps that 1, fruits are harvested 5-7 days delayed after being fully ripe, the diseased fruits are removed, the fruits are stored for 1 month to 3 months at the temperature of 0 DEG C-1 DEG C in bags; 2, the seeds are separated, washed clean and stored in sand immediately; 3, the seeds are taken out, washed clean, soaked in 1.5% glacial
acetic acid for 24 h, washed with
sterile water 3-5 times, poured into mixed liquid of IBA with the concentration of 200 mg / L and LNAA with the concentration of 500 mg / L to be soaked for 24 h and then placed in an
incubator at the temperature of 24+ / -2 DEG C for dark culturing and root promoting; 4, when the mouths of the grape seeds are cracked and white root tips come out, plug seeding is conducted in a
greenhouse; 5, after the seeds are germinated, water is sprayed once to twice every day, the seeds are covered with
plastic film for heat preservation at night, and the
plastic film is removed after 10 a.m. in the
daytime, so that the condition that seedlings are damaged by too high temperature is prevented; 6, when 3-4 true leaves of the seedlings grow out, the seedlings are transplanted to
nutrient soil in non-
woven fabric bags, water is sprayed to the leaf surfaces 1-2 times every day in the first weak after
transplanting, and shading is conducted. According to the method, the
seedling forming rate of the grape seeds is significantly increased.
