Embodiment 11：
The present embodiment uses the wheat in the jointing stage obtained cold-resistant derivant in 1-10 of the embodiment of the present invention to carry out
Sprinkling is handled, influence of the research wheat cold-resistant derivant to wheat leaf blade physical signs.
Specific experiment is：Condition of culture of the selection in the jointing stage is consistent, the uniform field pipe of growing way plants wheat 60 and manages (pipe
A diameter of 20cm, pipe range 60cm, often 10 plants of wheats of pipe), it is divided into 12 groups (every group 5 is managed)；The pipe of 1-10 groups is planted respectively
The wheat cold-resistant derivant that wheat leaf blade sprinkling 1-10 of the embodiment of the present invention is prepared, wheat leaf is planted to the 11st, 12 group of pipe
Piece sprays clear water, wherein, the standard of sprinkling is：Blade is set to moisten completely, but liquid does not flow down；By the pipe of 1-11 groups after 12h
Plant wheat move into phjytotron carry out low temperature induction processing, low temperature induction processing terminate after by 1-11 groups pipe cultivation wheat again
Move to field growing.12nd group of pipe, which planted after wheat leaf blade sprayed clear water to be still grown in the field, (records two days highest temperatures as 23
DEG C, the lowest temperature is 5 DEG C, 12.7 DEG C of temperature on average).After 1-11 groups pipe cultivation wheat moves to field growing 12 hours, take respectively
The most upper expansion leaf of 1-12 group wheats plants wheat as control using the 12nd group of pipe, determines 1-12 groups respectively as research object
Pipe plants the content of MDA in the most upper expansion leaf blade of wheat, soluble sugar, soluble protein and proline, and it the results are shown in Table 1.
Wherein, the process of the low temperature induction processing is：The temperature of phjytotron is reduced to 0 with 2 DEG C/h speed
DEG C, and temperature is maintained into 0 DEG C of 48h, the temperature of phjytotron is then increased to by outdoor temperature with 2 DEG C/h speed.
In this experiment, mda content is determined using thiobarbituricacidα- method side, and soluble sugar content uses anthrone colorimetric
Method is determined, and soluble protein content is determined using Coomassie brilliant G-250 method, and proline content is surveyed using acid ninhydrine method
It is fixed.
MDA is one of product of Lipid peroxidation metabolism, the size of the big I reaction film degree of injury of its content, therefore
The content of MDA is a common counter in plant senescence physiology and Resistance Physiology research.As shown in Table 1, in this experiment
The content of MDA significantly raises in 11 groups of wheat leaf blades, and sprays in the 1-10 group wheat leaf blades of cold-resistant derivant the third two
The content of aldehyde differs smaller with the 12nd group of wheat, it can be seen that low temperature can be relieved by spraying cold-resistant derivant of the present invention
Coerce the injury to wheat leaf blade cell membrane.
Soluble sugar, soluble protein and proline are the osmotic adjustments of Chinese medicine in plant cell, to improving plant
Total metabolism it is horizontal, to maintain plant osmosis regulating power to have the function that important, under the conditions of low temperature stress, the 11st group in this experiment
The content of soluble sugar, soluble protein and proline is relatively low in wheat leaf blade, differs larger with the 12nd group；And sprayed cold-resistant
The content of soluble sugar, soluble protein and proline is higher in the 1-10 group wheat leaf blades of derivant, with the 12nd group of wheat
Difference is smaller, it is possible thereby to illustrate that soluble sugar in wheat leaf blade, soluble protein can be improved by spraying cold-resistant derivant of the present invention
With the content of proline, the metaboilic level and osmotic adjustment ability of wheat can be improved to a certain extent, so as to improve itself
Resist the influence of extraneous low temperature.
Influence of the wheat cold-resistant conditioning agent of table 1 to wheat seedlings blade indices
Embodiment 12：Influence of the cold-resistant derivant to wheat yield
The present embodiment uses the wheat in the jointing stage obtained cold-resistant derivant in 1-10 of the embodiment of the present invention to carry out
Sprinkling is handled, influence of the research wheat cold-resistant derivant to wheat yield.
Specific experiment is：Condition of culture of the selection in the jointing stage is consistent, the uniform field pipe of growing way plants wheat 60 and manages (pipe
A diameter of 20cm, pipe range 60cm, often 10 plants of wheats of pipe), it is divided into 12 groups (every group 5 is managed)；The pipe of 1-10 groups is planted respectively
The wheat cold-resistant derivant that wheat leaf blade sprinkling 1-10 of the embodiment of the present invention is prepared, wheat leaf is planted to the 11st, 12 group of pipe
Piece sprays clear water, wherein, the standard of sprinkling is：Blade is set to moisten completely, but liquid does not flow down；By the pipe of 1-11 groups after 12h
Plant wheat move into phjytotron carry out low temperature induction processing, low temperature induction processing terminate after by 1-11 groups pipe cultivation wheat again
Move to field growing.12nd group of pipe plants wheat leaf blade and sprayed the latter disposed upright of clear water in field growing.Treat that 1-12 groups wheat is given birth to
It is long to after the maturity period, investigating 1-12 groups pipe cultivation wheat single-strain tassel number, grain number per spike, mass of 1000 kernel and the every yield of pipe wheat respectively,
Using the 12nd group as control, count different cold-resistant derivants influences on wheat yield and its constituent element, and it the results are shown in Table 2.
Wherein, the process of the low temperature induction processing is：The temperature of phjytotron is reduced to 0 with 2 DEG C/h speed
DEG C, and temperature is maintained into 0 DEG C of 48h, the temperature of phjytotron is then increased to by outdoor temperature with 2 DEG C/h speed.
As shown in Table 2, do not spray cold-resistant derivant low-temperature treatment the 11st group of pipe plant the single-strain tassel number of wheat, grain number per spike,
The 12nd group of mass of 1000 kernel and often pipe yield more low-temperature treatment reduces by 1.2,14.8,8.9g and 31.3g respectively, and sprays
The 1-10 groups of cold-resistant derivant only reduce by 0.4,5.2,5.3g and 15.1g compared with the 12nd group.Sprayed cold-resistant induction
The 1-10 groups of agent have certain protective effect compared with the 11st group, it is average increase respectively 0.8,9.7,4.4g and
16.2g.It can be seen that cold-resistant derivant of the present invention mainly increases the yield of wheat by increasing mature spike number and grain number per spike.
Influence of the wheat cold-resistant derivant of table 2 to wheat yield
