Problems solved by technology

Other areas are gradually introducing and cultivating them, but the seed coat of Physalis edulis is hard, the air permeability is poor, and the germination rate is very low, usually only about 20%, and it takes more than 15 days to germinate, which seriously affects the promotion of Physalis edulis nationwide application

Embodiment 1

[0022] A method for improving the germination rate of Physalis edulis seeds, comprising the following steps:

[0023] (1) Select high-quality seeds

[0024] From September to October, harvest when the external calyx of the Physalis edulis fruit is yellow, the fruit is light yellow, and the fragrance is strong. It is forbidden to harvest after rain or irrigation. The seeds obtained from the naturally shedding fruit after ripening are of the best quality.

[0025] After the Physalis fruit is harvested, put it into a seed collection pool with a thickness of no more than 40cm, and ensure that the temperature in the pool does not exceed 45°C. After 2 days of post-ripening, take out the seeds with jelly, and wash them repeatedly with water to remove the pulp and juice. , let the seeds settle and separate, then wash the seeds with clean water and put them in a drying bed, place them in a dry and ventilated place to dry in the shade, and when the water content of the seeds drops below...

Embodiment 2

[0036] A method for improving the germination rate of Physalis edulis seeds, comprising the following steps:

[0037] (1) Select high-quality seeds

[0038] From September to October, harvest when the external calyx of the Physalis edulis fruit is yellow, the fruit is light yellow, and the fragrance is strong. It is forbidden to harvest after rain or irrigation. The seeds obtained from the naturally shedding fruit after ripening are of the best quality.

[0039] After the Physalis fruit is harvested, put it into a seed collection pond with a thickness of no more than 40cm, and ensure that the temperature in the pond does not exceed 45°C. After 2.5 days of post-ripening, take out the seeds with jelly, and wash them repeatedly with water to remove the pulp, Juice, let the seeds settle and separate, then wash the seeds with clean water and put them in a drying bed, place them in a dry and ventilated place to dry in the shade, and when the moisture of the seeds drops below 8%, use...

Embodiment 3

[0050] A method for improving the germination rate of Physalis edulis seeds, comprising the following steps:

[0051] (1) Select high-quality seeds

[0052] From September to October, harvest when the external calyx of the Physalis edulis fruit is yellow, the fruit is light yellow, and the fragrance is strong. It is forbidden to harvest after rain or irrigation. The seeds obtained from the naturally shedding fruit after ripening are of the best quality.

[0053] After the Physalis fruit is harvested, put it into a seed collection pool with a thickness of no more than 40cm, and ensure that the temperature in the pool does not exceed 45°C. After 3 days of post-ripening, take out the seeds with jelly, and wash them repeatedly with water to remove the pulp and juice. , let the seeds settle and separate, then wash the seeds with clean water and put them in a drying bed, place them in a dry and ventilated place to dry in the shade, and when the water content of the seeds drops below...

Abstract

The invention relates to a method for increasing germinating rate of seeds of physalis pubescens. The method comprises the following steps of (1) selecting high-quality seeds; (2) soaking the seeds, and disinfecting by a potassium permanganate solution; (3) treating by hydrogen peroxide; (4) treating by gibberellin; (5) promoting germinating. The method has the advantages that the seeds are soaked by the strong oxidant of hydrogen peroxide, and the greasy matter at the surface of the seed is corroded, so that the permeability of the seed is enhanced; the seeds are soaked by the gibberellin, so that the cracking and differentiating of cells are accelerated, and the development of seed embryos is promoted; the proper germinating promoting temperature is selected, so that the nutrients of the seeds are quickly decomposed and transferred to the embryos to grow; the germinating rate of the seeds of the physalis pubescens is increased from 20% to 65% or above, and the germinating time is shortened by about 7 days; the effective measure is provided for production practices.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for improving the germination rate of Physalis physalis seeds. Background technique [0002] Physalis is a Physalis plant in the family Solanaceae, native to America, and now distributed in tropical and temperate regions. It bears spherical berries, about 1.2 cm in diameter, and the fruit is yellow when ripe, also known as "Huang Niu". The berries have a strong fragrance and are rich in vitamins, minerals and 18 kinds of amino acids. The calcium content is 73.1 times that of tomatoes and 13.8 times that of carrots. The content of VC is 6.4 times that of tomatoes and 5.4 times that of carrots. The fruit of Physalis edulis is not only edible, but also has high medicinal value. It has the functions of clearing away heat and detoxification, and diuresis. It is a new type of health-care fruit and vegetable. At present, it has been popularized and planted in Jilin and He...
