Problems solved by technology

It is also an excellent nectar source for brewing high-grade honey; Nanjing linden flower and bark can be used as medicine, and its infusion has the effects of sedation, sweating, antispasmodic and antipyretic; stem bark contains tannin, fat, wax and pectin, etc. To treat symptoms such as fatigue, chronic cough, etc., Nanjing Tilia seeds have a deep dormancy habit, and it usually takes 2-3 years to germinate, which seriously hinders the reproduction of Nanjing Tilia seeds. In the germination stage of Nanjing Tilia seeds, often Due to the lack of effective treatment methods, the seeds rot and the seeds are empty, which seriously affects the planting and promotion of seedlings.

Embodiment 1

[0026] A treatment method for improving the germination rate of Nanjing Tilia seeds comprises the following steps:

[0027] Step 1: Seed pretreatment, after collecting the seeds, soak them in clean water;

[0028] Step 2: Seed disinfection treatment, take out the soaked seeds in step 1, rinse the seeds with sterile water, soak them in 75% ethanol for 40 seconds, and then put them in 0.3% potassium permanganate Soak and disinfect for 3 minutes, rinse with sterile water several times after taking it out, and use filter paper to absorb the floating water on the surface;

[0029] Step 3: Seed soaking treatment, soaking the sterilized seeds in step 2 in a gibberellin hormone solution of 500mg / L-1000mg / L for 6h;

[0030] Step: 4: Prepare the culture medium. While soaking the seeds in step 3, mix the culture medium, adjust the pH value to 5.8-6.0, heat the culture medium in a microwave oven until it boils, and use a sterilized glass rod to carry out Stir, after the stirring is comp...

Abstract

The invention belongs to the technical field of tree propagation, and particularly relates to a treatment method for increasing the germination rate of tilia miqueliana seeds. The treatment method comprises the following steps of 1, seed pretreatment; 2, seed disinfection treatment; 3, seed soaking treatment; 4, preparation of an induction culture medium; and 5, seed coat treatment. The seeds aresoaked in a gibberellic hormone solution, and then the soaked seeds are peeled, so that germination of the peeled tilia miqueliana seeds is effectively promoted, and the germination rate of the seedsis increased; and dormancy breaking and germination of the seeds are promoted through the gibberellic hormone solution, and the tilia miqueliana seeds which are soaked in the gibberellic hormone solution and peeled are cultured and germinated in the culture medium, so that mineral nutrition required by tilia miqueliana seed growth is guaranteed in the culture medium, seed growth is promoted to behealthy and strong, resistance is enhanced, seed vigor is improved, the germination rate of the tilia miqueliana seeds can reach 80% or above, the germination rate is high, batch propagation can be achieved after management, and planting and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of tree propagation, in particular to a treatment method for improving the germination rate of Nanjing linden seeds. Background technique [0002] Nanjing linden (scientific name: Tilia miqueliana Maxim.) is a plant of the genus Tilia in the family Tiliaceae. It likes warm and humid climates, has strong adaptability, is resistant to drought and barrenness, and can improve soil. Greening tree species can be used as street trees, square greening and garden greening. Nanjing linden wood is white and soft, and can be used for construction, furniture, papermaking, carving, joinery and other materials. The bast fiber is developed, commonly known as "bass hemp", which can be used for artificial cotton, rope and weaving. It is also an excellent nectar source for brewing high-grade honey; Nanjing linden flower and bark can be used as medicine, and its infusion has the effects of sedation, sweating, antispasmodic and...
