Abstract
The invention discloses a method for initiating grass seeds. The method comprises the following steps: 1) seed selection; 2) preparing polyethylene glycol solution with osmotic potential of-0.5 to-2.0 Mpa; 3) pouring the PEG solution into a container, then placing a semipermeable membrane with the same size on the solution, then placing the seeds to be treated on the semipermeable membrane, and placing for 7-14 days at the temperature of 10-20 ℃; 4) drying at 25 deg.c for 24 hr or direct seeding without drying. The invention adopts the semipermeable membrane to control the seed water absorption process, avoids the direct contact of the seeds with the solution, is suitable for the initiation treatment of high-value grass flower seeds, and is particularly suitable for pansy and other seeds with mucus on the surface and petunia and other particle seeds.
Description
Technical field
The present invention relates to seed treatment and seed physiology application technology, relate in particular to a kind of showy flowers of herbaceous plants seed and cause processing method.
Background technology
It is that the control seed slowly absorbs moisture and makes its second stage that rests on imbibition that seed causes, and lets seed carry out the Physiological and Biochemical Metabolism and the repair of presprouting, seed is in prepare the metabolism state that germinates, but prevents stretching out of radicle.Through the seed that causes, vigor strengthens, strong stress resistance, and it is fast and neat to emerge, and planting percent is high.The patent application of domestic existing multinomial relevant seed elicitation technique, CN101411329A discloses a kind of tobacco seed initator; CN1190123C discloses a kind of solid initiating method that improves seed vitality; CN100420381C discloses a kind of seed initiator.
Showy flowers of herbaceous plants seeds such as pansy, petunia, Impatiens Hybriden, primula, impatiens, Salvia, Verbena are important flower bed flowers; Factorial seedling-culturing method is all adopted in scale showy flowers of herbaceous plants production at present; Obtain fast and the seedling of neat and consistent is grower's active demand; And the seed initiation can at utmost improve seed vitality, is obtaining neat emerging fast in the temperature range widely.Most showy flowers of herbaceous plants seeds are small, and like petunia etc., part showy flowers of herbaceous plants the surface of the seed has mucus, like Salvia japonica, pansy.Existing elicitation technique is not suitable for above-mentioned showy flowers of herbaceous plants seed and causes processing; Initiation is not suitable for handling particulate showy flowers of herbaceous plants seed like sand; The solution soaking initiating method is not suitable for handling the seed that there is mucus on surfaces such as pansy; Because expand in slime layer suction back, have influence on exchange gas, thereby influenced the presprouting of seed.
Summary of the invention
One of the object of the invention is to provide a kind of showy flowers of herbaceous plants seed initiating method; It is fit to the seed that there is mucus on surfaces such as particle seed such as petunia and pansy, can quicken showy flowers of herbaceous plants seed sprouting speed, emerges ahead of time; Shorten seedling raise period and cycle, improve seed planting percent under the uncomfortable environmental condition.
To achieve these goals, the invention provides a kind of showy flowers of herbaceous plants method for treating seeds, it is characterized in that it comprises the steps:
1) seed cleaning with pending seed cleaning, is removed impurity.
2) prepare polyethylene glycol (PEG) solution of osmotic potential between-0.5 to-2.0Mpa.
3) PEG solution is poured in the container; The about 1cm of thickness; On solution, place an onesize semipermeable membrane then; Then pending showy flowers of herbaceous plants seed is placed above the semipermeable membrane, cover the lid that has aperture 10 ℃ of-20 ℃ of condition held 7-14 days, 25 ℃ are returned to do 24 hours or do not return and do directly sowing.
Compared with prior art, method provided by the invention has the following advantages and good effect:
1) being fit to the surface has the seed of mucus to cause, and seed directly is not immersed in the solution, absorbs water through semipermeable membrane, and the seed elicitation procedure can obtain sufficient oxygen, but need not wash seed convection drying or sowing after causing end.
2) suitable high value particulate showy flowers of herbaceous plants seed causes, and has overcome to be not easy the shortcoming with the seed separation after solution soaking initiating method and sand initiating method cause this type of seed, adopts the initiation of the inventive method seed to finish the easy Hui Gan in back.
Embodiment
Embodiment 1
Take by weighing the selected pansy seed of 10 grams, 295 gram PEG 20000 are dissolved in 1 kg of water, be configured to the solution of osmotic potential for-1.0Mpa; Pour into then in the container that diameter is 40cm; Highly be 1cm, on solution, placing one deck diameter then is the semipermeable membrane of 40cm, above 10 gram pansy seeds evenly are placed in; Cover lid was 10 ℃ of condition held 14 days.Causing the back that finishes takes out seed and places in 25 ℃ of drying boxes after oven dry to the safe water content sealing storage or preserve in 4 ℃ of conditions and sow in next week.
Embodiment 2
Take by weighing the selected petunia seed of 1 gram, 366 gram PEG 20000 are dissolved in 1 kg of water, be configured to the solution of osmotic potential for-1.5Mpa; Pour into then in the container that diameter is 30cm; Highly be 1cm, on solution, placing one deck diameter then is the semipermeable membrane of 30cm, above 1 gram petunia seed evenly is placed in; Cover lid was 15 ℃ of condition held 12 days.Causing the back taking-up seed that finishes places the interior oven dry of 25 ℃ of drying boxes or directly carries out follow-up pill processing.
Embodiment 3
Take by weighing the selected scarlet sage seed of 10 grams, 431 gram PEG 20000 are dissolved in 1 kg of water, be configured to the solution of osmotic potential for-2.0Mpa; Pour into then in the container that diameter is 50cm; Highly be 1cm, on solution, placing one deck diameter then is the semipermeable membrane of 50cm, above 10 gram pansy scarlet sage seeds evenly are placed in; Cover lid was 20 ℃ of condition held 7 days.Cause the back that finishes and take out seed storage completion sowing in two weeks under 4 ℃ of conditions.
Seed in the foregoing description is taken out 200 carry out indoor germination experiment, germinate to measure and undertaken by GB, each handles 50 seeds, four repetitions, and 3 days statistics germination vigoies, 7 days statistics germination rates, the result is following:
Germination effect measuring in the seed chamber
