Enough significantly improve percentage of seedgermination；And the processing group for removing pericarp either directly sows vernalization or cryopreservation 2~3
It is sowed again after month, there was no significant difference for germination percentage；Dry storage after seed is removed the peel, germination percentage are minimum.
The investigative test of embodiment two shows: the pericarp of polygonatum kingianurn seed is not the main original for influencing seed and sprouting
Cause.Although the extraseminal pericarp of polygonatum kingianurn to the sprouting of seed there are certain mechanical resistance, polygonatum kingianurn seed it is permeable
Property it is good, thus pericarp be not influence seed sprout the main reason for.The fresh seeds of harvesting are sowed directly in sand bed and are urged
Bud can make the embryo of seed further reach maturity, and shorten the seed dormancy time, to improve the germination percentage of seed.
In conventional polygonatum kingianurn seed treatment, extraseminal pericarp will generally be removed, and in the mistake of pericarp removal
Certain damage is inevitably caused in journey to seed, to influence the sprouting of seed.In addition, polygonatum kingianurn seed belongs to low recalcitrant
Seed, therefore the dry storage or cryopreservation of either seed all will necessarily generate certain influence to the sprouting of seed.Cause
This, the 3rd group is not processed the optimization process method that directly sowing is seed in polygonatum kingianurn nursery, and this method technical difficulty
It is low, it is easy to operate, it is easy in seeling industry unit popularity.
