specific Embodiment

[0023] Silver Leaf Tilia seeds are collected in Hungary, with a clarity of 98.8%, a thousand-grain weight of 43.8g, and a kernel yield of 99.2%.

[0024] Firstly, mechanically peel off the fruit of Linden silver leaf, and then winnow the pure seeds without peel.

[0025] For 300g of pure seeds, do the following treatment: quickly scald with 100°C boiling water for 2 seconds, then quickly soak in water at room temperature for 24 hours; then soak in 200ppm gibberellin solution at room temperature for 24 hours; then use 200ppm cytokinin solution, Soak for 24 hours at room temperature.

[0026] Mix the soaked seeds with wet sand at a ratio of 1:3 by volume, put them into an enamel plate, cover with wet gauze to keep the water, sprinkle water and turn it regularly, and place it indoors (15°C-20°C) 5 days, and then placed in a 0-5°C refrigerator for 15 days.

[0027] The above-mentioned treated seeds are sown in plastic containers placed on low beds, and seedlings are raised in gr...

Abstract

The invention discloses a Tilia tomentose seed presprouting method. The method comprises the following steps: selecting fully mature new seeds, picking off the seed vessel mechanically firstly, carrying out quick burning and immersion treatment, then immersing the seeds in gibberellin and cytokinin, and finally carrying out presprouting through a temperature changing lamination method adopting a warm temperature before a low temperature. The method brings about a short breeding cycle and a high sprouting rate of Tilia tomentose. The ideal sprouting rate can be achieved for about 23 days. Compared with the conventional presprouting method, the presprouting method greatly shortens the time needed by the presprouting of the seeds to achieve the aim of the rapid breeding of Tilia tomentose, and solves the problem of seed resource waste caused by the low seed sprouting rate of Tilia tomentose.

Description

technical field [0001] The invention relates to a method for accelerating germination, in particular to a method for accelerating germination of Tilia argentina seeds. Background technique [0002] Tilia tomentosa, also known as Tilia tomentosa, Tilia tomentosa, etc., is a plant of the genus Tilia in the family Tiliaceae. Silver-leaved linden is mainly produced in the Balkan Peninsula, reaching northward to Hungary and western Ukraine, and extending eastward through Turkey to northwestern Syria. [0003] Silverleaf Tilia has strong adaptability, cold resistance, drought resistance and barrenness, and is an excellent shelterbelt tree species for water and soil conservation, windbreak and sand fixation, and water conservation. Silverleaf Tilia has a tower-shaped crown, dense branches and leaves, dark green leaves, and silvery white on the back of the leaves. Urban street trees and planted in parks and courtyards are excellent urban greening trees; they are resistant to prunin...
