Abnormal temperature germination accelerating process for rhododendron molle seeds

Abstract

The invention discloses an abnormal temperature germination accelerating process for rhododendron molle seeds, and particularly relates to the technical field of germination accelerating processes. When the rhododendron molle seeds are subjected to seedling acceleration, the rhododendron molle seeds are placed in a constant-temperature room for abnormal temperature seedling acceleration, meanwhile, the proper humidity and oxygen concentration around the rhododendron molle seeds are maintained, and the method greatly shortens the germination period of the rhododendron lapponicum seeds in a natural state, improves the germination rate of the rhododendron lapponicum seeds, can improve the seedling survival rate of the rhododendron lapponicum seeds through warm water disinfection and sterilization treatment, reduces the infection of diseases to the seeds and buds, meanwhile, reduces the production cost, is convenient to popularize and use, and provides a basis for popularizing planting of the rhododendron molle; and gamma rays are adopted to irradiate the seeds, the germination rate of the seeds is promoted, meanwhile, temperature-changing treatment is adopted to treat the rhododendron molle seeds, the protoplast viscosity of radicles of the rhododendron molle seeds is enhanced, the adaptability to low temperature is enhanced, and the stress resistance is enhanced.

Description

technical field [0001] The invention relates to the technical field of germination-promoting technology, and more specifically, the invention relates to a technology of anti-normal temperature germination-promoting technology of rhododendron japonica seeds. Background technique [0002] Pure yellow Rhododendron, small evergreen shrub, 0.2-1.7 meters high. Young branches scaled, often sparsely covered with slender hirsute. Leaf bud scales drop early. Leaf leathery, broadly elliptic, obovate to oblong-elliptic, green and shiny above, pale below, densely covered with scales, golden yellow to light brown. Short raceme terminal, with 3-6 flowers; corolla broadly campanulate, 1.5-3 cm long, bright yellow, 5-lobed. Capsule oblong or oblong-ovate. The flowering period is May. Born in miscellaneous woods or bamboo thickets, 2000-2800 meters above sea level. Produced in Yunnan and Tibet, China. It is also distributed in northeastern Myanmar. This species is cultivated artifici...

Problems solved by technology

[0003] Before the seeds of Rhododendron japonica are planted, the seeds need to be germinated. Due to the long natural germination cycle of Rhododendron japonica seeds, and during the germination process, different treatment techniques have different effects on the germination rate of the seeds. At the same time, during the treatment of the seeds, There will be problems of excessive water loss and high mold rate. Therefore, a process for accelerating germination of Rhododendron japonica seeds at abnormal temperature is needed.
