Embodiment 1

[0014] (1) Seed collection: On October 7, 2011, the shamrock maple samara was collected, and the wing was removed to obtain 140 whole seeds. (2) Seed pretreatment: Use pointed tweezers and surgery before the seed coat is not completely dried and hardened Use the blade to carefully peel off the outer seed coat, taking care not to damage the inner seed coat, so that the inner seed coat wraps the embryo intact, removes 64 empty seeds and 24 undeveloped aborted seeds, and obtains full seed coat with inner seed coat 52 The seeds are dried in the shade, wrapped in absorbent paper, and stored at room temperature in a sealed bag; (3) Seed disinfection treatment: On January 5, 2012, the stored plump seeds were soaked in 0.5‰ potassium permanganate solution for disinfection 10 Rinse 5 times in sterile water, soak in sterile water and let stand for one week at room temperature (replacing sterile water once a day); (4) Seed dormancy release: clean river sand in advance, and air-dry it with ...

Embodiment 2

[0016] (1) Seed collection: On October 18, 2011, Acer serrata was collected, and the wings were removed to obtain 150 whole seeds; (2) Seed pretreatment: Store the seeds in the shade and dry at room temperature; (3) Seed sorting: On January 18, 2012, the dried seeds were soaked in tap water for one week to remove 92 empty and aborted seeds from the floating upper layer, and 58 full seeds from the lower layer were collected for use; (4) Seed disinfection treatment: the full seeds should be at a height of 0.5‰ Soak and sterilize in potassium manganate solution for 10 minutes, rinse with sterile water 3 times, carefully peel off the outer seed coat while the seed coat is moist, soak in sterile water and let stand at room temperature for one week (replace sterile water once a day); (5) ) Seed dormancy release: clean the river sand in advance, sieve it with a 1mm sieve after air drying, spray with 5‰ potassium permanganate solution, cover and disinfect for one week and open for 3 day...

Abstract

The invention relates to a germinating treatment method of acer yangjuechi seeds. The germinating treatment method is characterized by comprising the following steps of: (1) seed collection: collecting winged fruits of acer yangjuechi in the first third and the second third of October, removing the fruit wings and obtaining complete seeds; (2) seed pretreatment; (3) seed sorting; (4) seed disinfecting treatment; (5) seed dormancy breaking; and (6) seed germination. The germinating treatment method comprises the following specific steps of: sowing the seeds with dormancy breaking into a germinating matrix, adopting garden soil, grass carbon and perlite with the volume ratio being 2:2:1, fully mixing, starting to germinate when the external temperature is 10-25 DEG C, expanding the seed leaves after 3 days, thus obtaining a normal and strong seedling with two true leaves after 5 weeks. The germinating treatment method has the advantages that the acer yangjuechi seedlings bred by the method has 34.5% germination rate, can be cultured by nursery garden, and the seedlings with neatness, consistency and excellent tree performance are generated so as to meet the greening requirement of urban and rural gardens, exert the ecological benefits, simultaneously be conductive to relieving the current critically-endangered living situation of the acer yangjuechi, expand the population quantity and realize conservation of endangered plants.

Description

Technical field [0001] The invention relates to a seedling cultivating method for breaking dormancy and promoting germination of the seeds of my country's unique and critically endangered and endangered plant-sirloin, belonging to the fields of rare and endangered plant protection, introduction and breeding, and biodiversity protection. Background technique [0002] Shofar maple ( Acer yanjuechi Fang et PLChiu is a deciduous tree of the genus Acer (Acer) of the Aceraceae family, a rare and endangered tree species unique to my country, a national secondary protected plant, and one of the critically endangered tree species in China (Yu Yongfu, 1999), found in the west of Zhejiang Province, my country In the valley broad-leaved forest at an altitude of about 800m in Tianmu Mountain, only 4 trees remained at that time. This species and Japanese croissant (Acer) produced in Hokkaido, Japan ( Acer miyabei Maxim) are very closely related, and the latter's large fossils (leaf and seeds) ...
