Abstract
The invention discloses a method for raising seedlings of redrlowered loropetalum. According to the method, based on the after-ripening characteristic of seeds of redrlowered loropetalum, seeds to be sown are stored by using sand at a variable and low temperature before sowing. The method for raising seedlings of redrlowered loropetalum, which is provided by the invention, is used to reduce germination time and increase rate of emergence.
Description
Technical field
The invention belongs to the field of plant breeding technology, in particular to a rubrum seed breeding methods.
Background technology
Rubrum (Loropetalum? Chinense? Var.rubrum) is rubrum (Loropetalum? Chinense) variant of its leaves safflower brilliant, colorful, its outstanding ornamental characteristics, strong adaptability, resistance, resistance to cutting , easy maintenance, made for the area south of the Yangtze River and has a rich garden uses one of the major leafed plants.Production rubrum propagation method is mainly cuttings, breeding mainly dependent Nutrition selection, coupled with the accelerated process of intensification of production in recent years, rubrum genetic diversity gradually by a few genotypes alternative, which rubrum genetic improvement and Germplasm is extremely unfavorable.Through sexual hybridization, seed multiplication can achieve genetic recombination, changing populations gene and genotype frequencies, can be separated from the fine filter out more new variant, but because production of the seed germination characteristics rubrum poorly understood, with not the Tibetan sand or sand reservoir with ordinary room temperature thermostat treated seed sowing method, seed germination and emergence rate is low and needs a long time, limiting its through sexual hybridization, seedling selection methods such as genetic improvement and germplasm application.
Summary of the invention
The present invention aims to overcome the existing rubrum seed breeding technology in the germination rate, germination rate is low and the problem of long incubation time, provides a rubrum seed breeding methods.
In order to achieve the above object, technical scheme provided by the invention is:
The rubrum seedling seed, comprising the steps of:
(A) in the form of early October harvest ripe rubrum fruit, dried 2 to 3 days after threshing, seed collection stand;
(2) threshing seed and moistening river sand were mixed in 1: 2 by volume～1: 3, preferably, seed mixed with moistening river sand in 1: 3 by volume, and it is for use from sealing plastic sack to pack into;
(3) packed seed is carried out variable temperature storage, wherein, the variable temperature storage step is:
A, with packed seed in 18 ℃ or 10 ℃ storage 10 days down;
B, will be through the seed of steps A storage 3～5 ℃ of storages 10 days down;
Twice of C, repeating step A and B;
D, will change 3～5 ℃ of storages down over to through the seed that step C handles;
It is moistening that duration of storage remains the grains of sand;
(4) variable temperature storage is after about 40 days, and seed is cut successively, at this moment can take out seed and carry out drilling or spill and broadcast; Broadcast the back and cover thin soil and hide seed, use withered grass (prune get off from turfgrass broken grass) to cover again, prevent to water and wash away seed and play heat insulation effect; After planting water permeable; Weather condition is regulated temperature and light intensity with the method for adding a cover plastic film and sunshade net during according to sowing, and suitable temperature is 15-25 ℃, and intensity of illumination is 150～600 μ molm
-2S
-1Under the condition, about about 12 days, cotyledon was unearthed successively.
Compared with prior art, beneficial effect of the present invention is presented as:
The method according to the present invention rubrum seedling seed ripening characteristics with, the use of variable-temperature, low-temperature method of treating Sand rubrum sowing seed treatment, the application of the present invention rubrum seed breeding methods can significantly shorten Seed germination time (autumn takes time about 10-13 days, sowing takes time about 11-14 days), increased seedling emergence (autumn> 90%, spring> 70%)
Embodiment
Below in conjunction with embodiment the present invention is further described.
Embodiment 1:
Form in early October harvest ripe rubrum fruit, dried 2 to 3 days after threshing, seed collection stand; would threshing seeds with moist sand mix ratio of 1:3 by volume, into self-sealing plastic bag stand ; the seed bags were stored at 18 ℃ for 10 days, and then the seed storage under 3 ~ 5 ℃ 10 days, repeat the previous two steps for storage, and then transferred to the ambient temperature of the seed 3 ~ 5 ℃ under the conditions of storage , always keep the sand moist during storage; 40 days later, after another break seeds, remove the seeds for sowing, sowing seeds after covering thin soil cover, and then hay (grass clippings from the lawn of grass clippings) cover to prevent water washed away the seed and from the insulation effect, irrigated after sowing, according to the weather conditions at planting time stamped with plastic film and shade net methods adjust the temperature and light intensity (optimum temperature 15-25 ℃, light intensity 150 ~ 600μmol · m

The nursery effect comparative trial of embodiment 3 seedling-cultivating method of the present invention and prior art
The nursery effect comparative trial and the effect of seedling-cultivating method of the present invention and prior art are as shown in table 1:
Test group 1 seedling method of the present invention; test group 2-4 nursery the prior art method as a control; access all the seeds in the test group for the same number of sampled seeds rubrum.
Table 1
Can find out from table 1; When using the planting seed of hiding or handling with the husky Tibetan of common normal temperature constant temperature method without sand, seed sprouting and the ratio of emerging lower (being lower than 15%), and need time long; Autumn sowing needs about 100-120 of time days, and spring sowing needs about 40-45 of time days.Sprout the time (autumn sowing needs about 10-13 of time days, and spring sowing needs about 11-14 of time days) and can shorten seed greatly, improve emergence rate (autumn sowing＞90% sows in spring＞70%) with this method.
