Abstract
The present invention relates to a kind of method for treating plant seed, specially breaks the method for having whisker iris hybrid seed dormancy, including peels off pericarp, spontaneously dries, and room temperature clear water immersion 48h, 300ppm 1000ppm6 BA solution immersion 12h 36h, take out sowing.After planting 46 60d or so sprout the processed seed of this method, and germination percentage is up to 75%；Whisker iris hybrid seed dormancy effectively is relieved, after planting 3 April of next year, germination advanceed to October then by sand storage under normal condition, and about 6 months or so in advance, germination percentage reached 75%.Accelerate iris breeding process.
Description
Technical field
The present invention relates to a kind of method for treating plant seed, specially breaks the method for having whisker iris hybrid seed dormancy.
Background technology
There is whisker iris to refer to the general designation for having beard adjunct iris on vertical valve.Be develop in modern age ornamental flower it is most rapid,
Most surprising, the kind increase of flower change also most a kind of iris.
People are by having the intermolecular hybrid of whisker iris kind come the various kind of acquired character, but the seed for having whisker iris is deposited
In the characteristic of dormancy.Conventional seed planting emergence evening, emergence rate are low, hamper the process of breeding.
Randolph[Randolph LF,Cox LG.Factors inlfuencing the germination of
Iris seed And the relation ofinhibiting substances to embryodormancy[J]
.Proc.Amer.Soc.hort.Sci.,1943,43:284-300.] think there is the germination inhibitor in whisker iris seed endosperm
Matter hinders seed sprouting and the growth of seedling, cuts off endosperm tissue completely or by its inhibiting substances leaching into water, and seed is stopped
Dormancy is released from [Arditti J.and Pray TR.Dormancy factors in Iris (Iridaceae) seeds [J]
.American Journal ofBotany,1969,56(3):254-259.].The special construction of kind skin passes through following side
Face suppresses the sprouting of seed, and planting the impermeability of skin prevents the moisture of sufficient amount from reaching embryo；The breathing of kind skin limitation seed is made
With so that seed cannot impact the gas permeability of seed with external world's progress gas exchanges；The mechanical inhibition of kind skin
Limitation embryo is dashed forward [Zhou Xia, Yao's seed dormancies Advance of Physiology summary [J] Anhui agronomy circular (the second half of the month such as break in the seed coat
Periodical), 2012,16 (14):51-53., Fan Lu, Li Shujuan, Zhang Ruilian illumination and kind skin are to there is the influence that whisker iris seed is sprouted
[J] Chinese agricultures are circulated a notice of, 2012,26 (12):200-202.] principal element that causes iris hybrid seed dormancy is
The effect of kind skin and endosperm, planting the effect of skin and endosperm includes mechanical resistance and contains inhibiting substances.
Hormone is inside plants trace signal molecule, and having on the whole developmental process of plant influences.Plant hormone treatment method
It is one of method for breaking iris seed dormancy.Diao Xiaohua have studied shadow of the gibberellin to Jris Four Plants seed dormancy
Ring, it is found that yellow flag seed is sprouted in gibberellin processing has facilitation, and swallow is spent, the seed pair of sword-like iris seed and small stream sweet-smelling grass
Gibberellin reaction is insensitive, and [Diao Xiaohua, high also tetra- kinds of iris seed germination and dormancies of jade-like stone are not ground germination rate for promotion
Study carefully [J] seeds, 2006,25 (4):41-44.].Research in terms of to there is whisker iris hybrid seed breaking dormancy still belongs to blank.
The content of the invention
For above-mentioned technical problem, it is an object of the invention to provide a kind of side for breaking and having whisker iris hybrid seed dormancy
Method, shifts to an earlier date the germinating time of its seed, and improves germination percentage.Concrete technical scheme is：
Breaking has the method for whisker iris hybrid seed dormancy, comprises the following steps：
Collection maturation has whisker iris to hybridize fruit, peels off pericarp, chooses full seed, through spontaneously drying, is placed in ox-hide
Paper bag room temperature storage；
When sowing, the seed of storage is taken out and is placed in room temperature clear water immersion 48h；
The soaked seed of clear water is taken out, is placed in 300ppm-1000ppm 6-BA solution immersion 12h-36h, taking-up is broadcast
Kind.
6-BA is 6- benzyl aminoadenines.
Provided by the invention to break the method for having whisker iris hybrid seed dormancy, after planting 46-60d is left for processed seed
The right side, germination percentage is up to 75%；Whisker iris hybrid seed dormancy effectively is relieved, by the after planting next year 3- of sand storage under normal condition
April, germination advanceed to October then, and about 6 months or so in advance, germination percentage reached 75%.Accelerate iris breeding process.
Embodiment
Illustrate the present invention with reference to embodiment, the embodiments described herein scheme, does not limit the present invention, the skill of this area
Art personnel spirit according to the invention, can make improvements and change, and the such modifications and variations are regarded as this
In invention scope, the scope of the present invention and essence all have the right requirement to limit.
Embodiment 1
Using the hybrid seed for having the short dream of whisker iris and flat valve powder.
The hybridization fruit that collection on June 25 pericarp will crack, peels off pericarp, chooses full seed, through spontaneously drying, put
In kraft paper bag room temperature storage.
August 16 days, takes out the seed of storage, is placed in clear water and soaks 48h.
Soaked seed is taken out, be respectively placed in 500ppm and 1000ppm 6-BA solution soak 12h, 24h and
36h。
After seed treatment, routinely type of seeding is sowed and managed.
October 4, seed are sprouted, and to October 18, the germination rate respectively handled reached 60-75%.It is molten with 1000ppm6-BA
It is up to 75% that 12h, which handles germination rate, in liquid.
Embodiment 2
Using the hybrid seed of You Ran irises India head and Bai Yuhuang.
The hybridization fruit that collection on June 25 pericarp will crack, peels off pericarp, chooses full seed, through spontaneously drying, put
In kraft paper bag room temperature storage.
August 16 days, takes out the seed of storage, is placed in clear water and soaks 48h.
Soaked seed is taken out, be respectively placed in 300ppm, 500ppm and 1000ppm6-BA solution soak 12h,
24h and 36h.
After seed treatment, routinely type of seeding is sowed and managed.
October 8, seed are sprouted, and to October 18, the germination rate respectively handled reached 50-70%.It is molten with 500ppm6-BA
It is up to 70% that 24h, which handles germination rate, in liquid.
