Problems solved by technology

However, due to the small size of the seeds of Clematis pachyphyllum and post-ripening phenomenon in the embryo, the highest emergence rate of conventional methods is only 20.33%. It can be seen that the establishment of a method for promoting the germination of Clematis pachyphyllum seeds can be beneficial for the Tibet Plateau. The construction of ecolo

Embodiment 1

[0028] A method for promoting the germination of clematis pachyphyllum seeds, specifically comprising the following steps:

[0029] (1). The collected seeds are placed under outdoor ventilation conditions with sufficient light (the growth environment of the thick calyx and the printed iron wire);

[0030] (2). In March of the second year, remove the seed hair from the seeds of step (1), and soak in clear water for 24 hours under dark conditions;

[0031] (3). Divide the fully water-absorbed seeds in step (2) into 3 parts on average, 100 grains per part, and soak them in 50mg / kg and 100mg / kg respectively at a temperature of 5-15°C (room temperature). , 200mg / kg of IAA solution for 24 hours, then the seed surface was cleaned 4 times with distilled water;

[0032] (4). The seeds cleaned in step (3) are evenly drilled in the outdoor seedling field, 100 seeds in each row, and the surface is covered with fine river sand with a thickness of 2mm; temperature is -5 to 15°C, and humidi...

Embodiment 2

[0037] A method for promoting the germination of clematis pachyphyllum seeds, specifically comprising the following steps:

[0038] (1). The collected seeds are stored under dark and ventilated conditions at a room temperature of 5-10°C;

[0039] (2). Soak the seeds of step (1) in clear water for 24 hours under dark conditions in March of the second year without removing the seed hairs;

[0040] (3). Divide the fully water-absorbed seeds in step (2) into 3 parts on average, 100 grains per part, and soak them in concentrations of 50mg / kg, 100mg / kg, 200mg / kg at a temperature of 20-25°C. kg of IAA solution for 24 hours, then the seed surface was cleaned 4 times with distilled water;

[0041] (4). The seeds cleaned in step (3) are evenly drilled on the seedbed in the protected area, 100 grains in each row, and the surface is covered with fine river sand with a thickness of 2mm; keep the temperature at 20-25°C and the air humidity at 70%;

[0042] (5). Continuously observe the se...

Abstract

The invention discloses a method for promoting germination of clematis tibetana var .vernayi seeds. The method comprises the following steps: (1), immediately harvesting big and plump wild clematis tibetana var .vernayi seeds free of pests and diseases after the seeds mature in October; (2), storing the harvested clematis tibetana var .vernayi seeds under a dark and ventilated condition and at theroom temperature of 5-10 DEG C; (3), in March in the second year, soaking the seeds in clear water for 24 hours under a dark condition, without removing seed hair; (4), soaking the seeds in an IAA solution with the concentration of 100 mg/kg, keeping the temperature at 20-25 DEG C, and soaking for 24 hours under the condition; (5), then washing the surfaces of the seeds for 4 times by using distilled water; (6), sowing the seeds on a seedbed in a protected land with the temperature of 20-25 DEG C and the air humidity of 70%, and covering the surface with fine river sand with the thickness of2mm. By the method, the problem of difficult germination of the clematis tibetana var .vernayi seeds is solved very well, and the highest germination rate after 30 days is 82%.

Description

technical field [0001] The invention relates to the field of seed germination, in particular to a method for promoting the germination of clematis pachyphyllum seeds. Background technique [0002] Clematis tibetana var.vernayi is a perennial climbing plant of the genus Clematis in the family Ranunculaceae, also known as "Tibetan clematis". It is produced from eastern to southern Tibet and grows on barren slopes and shrubs at an altitude of 2200-4800 meters. , On the gravel river bank, it is also produced in western Nepal. It is a unique plant in the Himalayas. [0003] Clematis sinensis is an important pioneer plant in the barren slopes, bare land, and river beach gravel land with severe soil erosion from the east to the south of Tibet. The water and soil conservation plants can be used for ecological restoration of engineering slopes and ecological restoration of landslides. At the same time, the sepals of clematis chinensis in the thick calyx are large in fruit stage, an...
