Abstract
A method that can rapidly relieve the dormancy state of Nanjing linden is characterized in that after the mature fruit shell of Nanjing linden is firstly removed, the seed is treated with the concentrated sulfuric acid for fifteen to thirty minutes and then treated with a gibberellin solution in a density of 200 to 500 mg/L for twelve hours and finally the treated seeds are stacked with the sand for fifty days in the low-temperature condition of zero to five cent degrees. The germination percentage of the Nanjing linden seed released from the dormancy state can reach ninety percentages or above. The present invention can rapidly relieve the dormancy of the seed of Nanjing linden and has low treatment cost, which can promote the rapid germination of the seed, enlarge the breeding of Nanjing linden and meet the requirement of greening and forestation.
Description
One, technical field
The invention belongs to the preceding seed processing technology field of sowing in the production of forestry, be specifically related to the method for a kind of quick releasing tilia miqueliana (Tilia miqueliana) seed dormancy state.
Two, background technology
Lime tree is good afforestation seeds, belongs to one of the world's four big avenue tree plantings, and is important commerical tree species and good nectariferous plant.Tilia miqueliana (Tilia miqueliana) belongs to lime tree and belongs to Tiliaceae, is distributed in Chinese East China, is Chinese endemic tree, once in Jiangsu, Anhui, Jiangxi, Shanghai, zhejiang and other places extensively distributes.Because the artificial destruction of ecotope, the woods in blocks of present natural distribution are seldom, the existing a small amount of woodss in flakes in ground such as east, Zhejiang horizontal stroke, the precious Huashan, Nanjing, Anhui Huang Zangyu.Mainly as greening, Zhejiang Ling Xi, tower head temple remain 200 years living tilia miquelianas in cultivation at home, and tilia miqueliana was also once successfully introduced a fine variety on ground such as Beijing Botanical Garden and Qingdao Kunyu Shan Mountain.Tilia miqueliana happiness humid temperate climate, its adaptive capacity is strong, and the ability drought and barren has improving effect to soil.Tilia miqueliana is in the evolution of long period of time process, and for self species can continue for a long time, prevent natural disaster self species is caused destructive strike, its seed has formed the habit of deep dormancy, and nature resting stage reached more than 2 years.But also just because of this evolution habit of tilia miqueliana, the artificial propagation that has seriously hindered tilia miqueliana utilizes technical progress.
The progress of the problem of afforestation and seedling bound pair tilia miqueliana seed dormancy releasing at present is slow, does not still have the bibliographical information of removing tilia miqueliana seed dormancy method fast.
Three, summary of the invention
The present invention seeks a kind of technical method that can rapid relieving dormant state of nanjing linden seed, reaches to promote seed quick-speed germination, satisfy afforestation and enlarge the purpose of these fine tree species of plantation tilia miqueliana.
Technical solution of the present invention is:
A kind of method of rapid relieving dormant state of nanjing linden seed is characterized in that adopting following processing procedure with after the ripe shell removal of tilia miqueliana:
A. handle seed 15～30min with the concentrated sulfuric acid;
B. be the gibberellin (GA of 200～500mg/L again with concentration
3, down together) and solution-treated 12h;
C. place the long-pending 50d of mixed sand bed under 0～5 ℃ the cryogenic conditions then.
After above process processing, just can remove the tilia miqueliana Seed Dormancy.The tilia miqueliana percentage of seedgermination of breaking dormancy can reach more than 90%.
Four, description of drawings
Fig. 1 is the photo of tilia miqueliana fruit and seed, and the left side is the fruit of band shell, and the right side is the seed behind the removal shell;
Fig. 2 is the relation of concentrated sulfuric acid processing time and germination rate, and abscissa is the processing time of low temperature lamination among the figure, and unit is the sky; Ordinate is a percentage of seedgermination, represents with percentage, is up to about 9%; On behalf of the concentrated sulfuric acid, H15, H30, H45 handle 15min, 30min, 45min respectively.

3Solution; T6, T12, T18 represent the GA with each concentration respectively
3Solution soaking seed 6h, 12h, 18h.
Five, embodiment
Gather ripe tilia miqueliana fruit autumn, dry the back and remove shell, then:
A. use the concentrated sulfuric acid to soak 15～30min; The concentrated sulfuric acid is handled overlong time, can damage seed; Processing time is too short, weak effect, and seed dormancy is difficult to remove.The concentrated sulfuric acid is handled the relation of time and germination rate referring to accompanying drawing 2.
B. be the gibberellin (GA of 200～500mg/L again with concentration
3) solution soaking processing 12h.The relation of Gibberellins solution concentration and germination rate is referring to accompanying drawing 3.
The concentrated sulfuric acid is handled the relation of time, Gibberellins solution concentration, Gibberellins solution soak time and germination rate referring to accompanying drawing 4.
C. the process of surviving the winter of seed under the simulating nature state then placed seed under 0～5 ℃ the cryogenic conditions mixed sand bed long-pending about 50 days.
After above process processing, just can remove tilia miqueliana Seed Dormancy state.The tilia miqueliana percentage of seedgermination of breaking dormancy can reach more than 90%.
The present invention not only can remove the tilia miqueliana Seed Dormancy fast, and processing cost is also very low, has reached the purpose that promotes seed quick-speed germination, the breeding of expansion tilia miqueliana and satisfy the afforestation needs.
