Low temperature storage method for seeds of rubber tree

Abstract

The invention discloses a low temperature storage method for rubber tree seeds, which includes the processes that the seeds are selected, pretreated with a bactericide for disinfection, separately loaded in plastic film bags, stored at low temperature, etc. With simple technical process, the method can effectively solve the problem of poorer stability of the germination rate of rubber tree seeds in short and medium term storage through the processes of optimizing the initial condition of storage, controlling the aeration of the seeds and keeping the storage environmental condition stable, etc., thus ensuring that the germination rate of rubber tree seeds is stabilized over 60 % after a storage period of about one year; the method has promising prospect for generalization and application.

Description

technical field [0001] The invention relates to a storage method for recalcitrant seeds, in particular to a low-temperature storage method for rubber tree seeds. Background technique [0002] At present, a new technology of asexual propagation of rubber tree seedlings that is being promoted - rubber tree seedling budding technology, with its advantages of short seedling cycle, good quality of seedlings, and low labor intensity of workers, will completely change the way of cultivating rubber tree seedlings . However, because rubber tree seeds are moderately recalcitrant seeds, they have typical dehydration sensitivity. Under natural storage conditions, the seeds quickly lose their germination ability, while rubber tree seeds mainly mature in autumn, and the maturity period is concentrated, so they can be harvested. The time of seedling budding is not long (about 2~3 months), and just enters winter shortly after budding, and seedling growth is affected badly, thereby seriousl...

Problems solved by technology

[0004] The analysis of the reasons for the unstable effect of the above storage methods shows that, firstly, due to the large difference in the ripening period of the fruit or seeds, the consistency of the developmental stages of the seeds is poor; Changes in storage locations, seasons, and environmental meteorological factors, as well as interference from human factors, lead to different storage results

Due to the poor stability of the existing storage methods, it has not been well applied in production
