Abstract
The invention discloses a method for improving the seed germination rate of an ornamental woody plant euscaphis japonica, and relates to the technical field of plant cultivation. The method comprises the following steps: after spreading seeds of euscaphis japonica on a red-hot flat iron pot for 5 s at the highest speed, pouring the treated seeds into clear water immediately for being cooled; then, transferring the cooled seeds into 50-350 mg/L of a gibberellin 920 solution for being soaked for 6 h, wherein the volume of the gibberellin 920 solution is 5 times higher than that of the seeds; and then taking out the soaked seed for being sown.
Description
Technical field
The present invention relates to field of plant growing technology, more particularly to a kind of raising ornamencal flower and tree open country crow Chinese toon percentage of seedgermination
Method.
Background technology
Wild crow Chinese toon (Euscaphis japonica), is defoliation small arbor or the shrub of Staphyleaceae open country crow Toona, be it is a kind of very
There is the ornamental plant of Exploitative potential.This seed has the characteristic of deep-sleep, is such as left intact, and seed afterwards could for 2 years
Sprout or do not sprout, and germination rate is extremely low.Investigation to wild wild crow Chinese toon population finds that wild crow Chinese toon is all present with individual plant form
In border, barren hill, Xi Bian groups, seedling near plant, is had no.Although someone sporadicly inquired into the side that the accelerating germination of wild crow Chinese toon is processed
Method, such as Qi Zhenxiong (2012) take high water temperature thermal expansion facture, make seed sprout time do sth. in advance 1 year；Yang Yanling (2008) and
Chen Biliang (2006) has found that high temperature accelerating germination (seed soaking water temperature 65-70 DEG C) wet-storage, cool stratification accelerating germination etc. can improve seed
Germination percentage；Chen Cuili (2012) has certain Germination effect using Chinese liquor and 95% dense sulfuric acid treatment open country crow Chinese toon seed.But study carefully
Unexpectedly it is which kind of or which kind reason causes seed dormancy not do comprehensive system research, the method specific aim of process is not strong.
The broken dormant technology of seed simply has one of On Comprehensive Technique of accelerating germination in the species seedling culture of dormancy habit,
There is one-sidedness in the broken dormant technology of existing research open country crow Chinese toon, lack supporting technical system research；Treatment conditions are had high demands
The defect having high demands with treatment people professional standards, is limited to complete in experiment interior, and technology is received to the popularization and application of production field
To restriction.
The content of the invention
The technical problem to be solved be for prior art improving not enough present in wild crow Chinese toon percentage of seedgermination,
There is provided a kind of method for improving ornamencal flower and tree open country crow Chinese toon percentage of seedgermination.
Technical scheme is as follows：
A kind of method for improving ornamencal flower and tree open country crow Chinese toon percentage of seedgermination, is that wild crow Chinese toon seed is laid in burning with most fast speed
After red flat board iron pan upper 5 second, poured in clear water at once and lowered the temperature, then by seed proceed to the 50mg/L of 5 times of volumes of seed～
Soak in the gibberellin 920 solution of 350mg/L 6 hours, take out sowing afterwards.
Wild crow Chinese toon percentage of seedgermination is brought up to more than the 100% of primary bud rate by method of the present invention safety and economic, right
The expanding propagation of wild crow Chinese toon material and popularization and application have important function.
Specific embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment 1
For the mechanical obstacles of kind of shell, the method for taking localized hyperthermia's carbonization, seed is divided into into 3 parts, 300 per part, is put down respectively
It is layered on and burns static 5 seconds, 10 seconds and taking-up after 15 seconds, broken shell of lowering the temperature in being immediately placed in cold water on red flat board iron pan, breaks
The mechanical obstacles effect of cur's shell.Sow after the charing process of high temperature local, as a result show, the process percentage of seedgermination of 5 seconds reaches
16%-18%, embryo do not come to harm, and the seed for processing 10 seconds and 15 seconds does not germinate, and embryo blacks downright bad.
Presence to endogenous inhibiting substances, selects 1200 seeds, by seed broken shell after, be divided into 300 it is a, it is same with Shanghai
The gibberellin 920 of auspicious bio tech ltd's production is made into the concentration point of 50mg//L, 150mg/L, 250mg/L, 350mg/L
Jin Zhong not take out after 6 hours, sow, as a result show, the germination percentage of 4 process is followed successively by 34%, 42%, 37%, 31%, wherein
With the germination percentage highest of 150mg/L, up to 42%, it is seen that wild crow Chinese toon seed can be greatly improved by the combination of above-mentioned 2 kinds of methods
Germination percentage.
Claims (1)
1. a kind of method for improving ornamencal flower and tree open country crow Chinese toon percentage of seedgermination, it is characterised in that by wild crow Chinese toon seed with most fast
Speed is laid in after burning red flat board iron pan upper 5 second, is poured in clear water at once and is lowered the temperature, seed is proceeded to 5 times of bodies of seed then
Soak in the gibberellin 920 solution of long-pending 50mg/L～350mg/L 6 hours, take out sowing afterwards.
