Description

A kind of method improving Rhizoma Paridis seeding ratio
Technical field
The present invention relates to seed biology techniques field, be specifically related to use different disposal condition to increase Rhizoma Paridis seed sprouting The method of rate.
Background technology
Rhizoma Paridis (Paris polyphylla var.yunnanensis) is Liliaceae Paris Linnaeus(Paris L.) herbaceos perennial, It it is the former plant species of medicinal Rhizoma Paridis included of pharmacopeia.Its rhizome has heat-clearing and toxic substances removing, the function of relieving convulsion pain relieving, can be used for laryngopharynx swelling and pain, Infantile convulsion, venom, furuncle swelling toxin, external treatment furuncle and phyma, parotitis, is the Chinese patent medicines such as YUNNAN BAIYAO, GONGXUENING, sheet son Huang Primary raw material.For a long time, people rely on wild resource to the utilization of Rhizoma Paridis always, due to the most excessive predation formula Excavate, wild Rhizoma Paridis has suffered destructive destruction, has been on the verge of exhaustion, artificial growth become solution Rhizoma Paridis resource deficient Weary inevitable choice.
Rhizoma Paridis seed has hibernation feature, as allowed it naturally sprout, then needs within 15 months, just can emerge, and emergence rate is difficult to Reach 50%.And using cool stratification, the method for secondary alternating temperature, though can emerge in 1 year, but emergence rate is only 60%.Its reason It is differentiation not exclusively (form after-ripening) and the plumular axis after-ripening (physiology after-ripening) of Rhizoma Paridis embryo.
Form after-ripening i.e. refers to the stage ripe from seed maturity to embryo, and embryo is slowly growth and sizing in seed.Yunnan weight The seed gathered after building fruit maturation, is seed maturity.The embryo of mature seed is the most immature, and at this moment the form composition of embryo is the most not Perfect, it is impossible to germinate.Under suitable epidemic disaster and air conditions, embryo starts differentiation and growth, differentiates cotyledon, plumule, embryo Axle and radicle, be basically completed the construction of idiosome, and this phase is form after-ripening.After embryo completion morphology after-ripening, give to be suitable for sending out The environmental condition of bud, seed still can not be unearthed sprouting at once, needs the cryogenic conditions of certain time, and plumular axis is by after its physiology Ripe, seed could be sprouted.The seed completion morphology after-ripening of Rhizoma Paridis and two stages of physiology after-ripening under field conditions (factors), i.e. from fruit The real ripe time needing 15 months to seed germination.
Breeding about Rhizoma Paridis, domestic scholars done numerous studies, Li Yunchang (Li Yunchang, Rhizoma Paridis asexual numerous Growing, Yunnan plant is studied, 1986,8 (4): 429-435) numerous studies have been done in the seminal propagation of Rhizoma Paridis, Rhizoma Paridis seed from So sprouting, the most treated and be directly sowed at cool canopy seedbed, within 15 months, emergence rate is 46.2%.Li Heng, Yang Xinghua are by Rhizoma Paridis The Morphological And Anatomical of seed germination is observed: during Rhizoma Paridis seed shedding, embryonic pole aplasia, but one the least, the most completely break up many Cell ellipsoid, albuminous cell thickness about and keratinization, inner face is filled with starch grain and other nutrient substance, makes endosperm group Knitting hardening, and be unfavorable for the entrance of air and moisture, the nutrient substance in seed also can not soften the dissolving material for easily absorbing As nutrition during embryonic development, therefore Rhizoma Paridis seed has been that the differentiation of embryo has latter stage of ripening.Li Yunchang analyzes Rhizoma Paridis The hibernation feature of seed, after using low temperature, moist preliminary treatment, high-temperature cultivation, although radicle continues to increase, rhizome, plumular axis are also Develop, but seed still can not break ground and emerge.Being primarily due to the poor growth of plumular axis, there is physiology after ripening in plumular axis, then Through K cryogenic treatment, then high-temperature cultivation, the growth of plumular axis can be effectively facilitated, seed breaks ground and emerges soon, makes the seed germination time shorten It is 10~12 months.This research shows, cool stratification can make Rhizoma Paridis embryo preferably grow, and temperature is to affect Rhizoma Paridis Seed Layer The key factor of long-pending effect.In terms of application exogeneous growth regulator promotes Rhizoma Paridis seed afterripening, most researchs still think suitable The germination rate processing beneficially Rhizoma Paridis seed when the gibberellins of concentration.
Although many about the research how improving Rhizoma Paridis seed germination rate, but researcher many sight is concentrated on single Change external condition in the impact of Rhizoma Paridis seed germination rate, and germination efficiency is the most very good, and in terms of emergence rate Researches.
The present inventor is by the comprehensive mechanism analyzing suppression Rhizoma Paridis seed germination, in conjunction with the feature of seed maturity, invention A kind of method that can substantially increase Rhizoma Paridis seeding ratio.By twice update search in 2013 to 2015 years, mesh Before at home and abroad find no the relevant report of this kind of method.
