Abstract
The invention relates to a plant seed treatment method, in particular to a method for breaking dormancy of hybrid seeds of bearded iris. The method comprises the steps that mature hybrid fruits of the bearded iris are collected, fruit peels are stripped off, and full seeds are selected, naturally dried and put into a kraft paper sack for normal temperature storage; the stored seeds are taken out and put into normal temperature clear water to be soaked for 48 h; the seeds soaked with the clear water are taken out and put into a hydrogen peroxide solution with the mass concentration of 10%-30% to be soaked for 30 min-90 min, and the soaked seeds are taken out and repeatedly washed with clear water to remove sticky liquid on the surfaces; the soaked seeds and wet fine river sand are mixed according to the proportion of 1:3, and the mixture is put into a refrigerator to be stored for 60 d at 5 DEG C. According to the method for breaking the dormancy of the hybrid seeds of the bearded iris, germinating conducted from March to April of the next year after sowing is conducted under conventional conditions is advanced to October of the current year, the germinating time is advanced about six months, seed germinating is achieved 15 d-20 d after seed sowing, the germinating rate reaches 90%, and the method is short in germinating time, high in germinating rate, ordered in seedling emergence and easy and convenient to operate.
Description
Technical field
The present invention relates to a kind of method for treating plant seed, the method being specially whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy。
Background technology
Having whisker Rhizoma Iridis Tectori is the general designation having beard appurtenance Rhizoma Iridis Tectori on vertical lobe。It is that ornamental flower in modern age is developed the class Rhizoma Iridis Tectori the rapidest, flower change is the most surprising, kind increase is also maximum。
People are by there being the intermolecular hybrid of whisker Rhizoma Iridis Tectori kind to carry out the kind that acquired character is various, but have the seed of whisker Rhizoma Iridis Tectori to there is the characteristic of dormancy。Conventional seed planting emerge late, emergence rate is low, hampers the process of breeding。
The hibernation feature of Rhizoma Iridis Tectori seed and the method for breaking dormancy are conducted in-depth research by experts and scholars both domestic and external, it is believed that Rhizoma Iridis Tectori seed dormancy exists following reason: the Germination suppression material in seed endosperm hinders the growth of seed germination and seedling；The impermeability of seed coat makes the moisture of q.s can not arrive embryo；The Repiration of seed coat restriction seed, so that seed can not carry out gas exchange with the external world, impacts the breathability of seed；The mechanical inhibition restriction embryo of seed coat breaks through seed coat etc.。The method one of breaking dormancy is to excise endosperm tissue completely or by its inhibiting substances leaching to water；Two is cool stratification；Three is chemical substance treatment；Four is ionizing radiation。
In reading up the literature, common gibberellins (GA3), 6-benzyl aminoadenine (6-BA), indolebutyric acid (IBA), concentrated sulphuric acid (H2SO4), sodium hydroxide (NaOH), potassium nitrate (KNO3) etc. chemical substance treatment Rhizoma Iridis Tectori seed, the method seeking to break Rhizoma Iridis Tectori dormancy, achieve certain effect, but effect be not ideal。Hydrogen peroxide (H2O2) be a kind of strong oxidizer, seed soaking can mild corrosion seed coat, promote the ventilating permeable of seed coat, simultaneously hydrogen peroxide (H2O2) also it is provided that more oxygen, making oxygen and water can arrive embryo by visible through the seed coat smoothly, thus breaking seed dormancy, promoting seed germination。Hydrogen peroxide (H2O2) agriculturally studying more as seed germination accelerant, have not been reported in the seed propagation of flowers。Research in having whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy still belongs to blank。
Summary of the invention
For above-mentioned technical problem, it is an object of the invention to provide a kind of method having whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy so that it is the germinating time of seed in advance, and improves germination percentage。Concrete technical scheme is:
The method having whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy, comprises the following steps:
Gather the ripe whisker Rhizoma Iridis Tectori that has and hybridize fruit, peel off peel, choose full seed, through natural drying, be placed in kraft paper bag room temperature storage；
The seed of storage is taken out and is placed in room temperature clear water immersion 48h；
Being taken out by soaked for clear water seed, being placed in mass concentration is 10%-30% hydrogen peroxide (H2O2) solution soaks 30min-90min after, seed is pulled out, repeatedly rinses with clear water, remove surface mucus；
The seed soaked mix with the ratio of wet thin river sand 1:3 by volume and is placed on 5 DEG C of refrigerator and preserves 60d。
The method having whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy provided by the invention, October then is advanceed to by after planting germinateing in next year 3-4 month under normal condition, about about 6 months in advance, 15d-20d germination after planting seed, germination percentage reaches 90%, and the method germinating time is short, and germination percentage is high, emerge neat, easy and simple to handle。
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described, embodiment scheme described here, it is not intended to the present invention, those skilled in the art is according to the spirit of the present invention, can make improvements and change, described these improve and change is regarded as in the scope of the invention, and the requirement of all having the right of the scope of the present invention and essence limits。
