Note: in table, experimental pharmacy is willow antifreezing agent prepared by embodiment 1.
Mid-August, first time sprays willow antifreezing agent.Sprayed 1 time every 15 days later, spray 3 times continuously, application times is 1, only sprays 1 time in mid-August, application times is 2, uses 2 times continuously at mid-August, 8 the end of month, and application times is 3, uses 3 times continuously in mid-August, 8 the end of month, mid-September.After first time sub-zero temperature, measure its chlorophyll fluorescence parameters, often organize mensuration 5 strain, every strain measures 5 blades, and secondary investigation terminal bud survival rate, investigates 30 strains.
3, experimental result and analysis
3.1 experimental result
After first time sub-zero temperature, measure its chlorophyll fluorescence parameters, often organize mensuration 5 strain, every strain measures 5 blades, and measurement result is in table 3.
Next year, Yang Dingya survival rate in investigation silver, 30 strains are investigated in each process, investigation result in table 3, Fig. 1 for after using willow antifreezing agent, the histogram of willow chlorophyll fluorescence parameters change; Fig. 2 for after using willow antifreezing agent, the histogram of willow terminal bud Overwintering Survival Percentage.
Yang Dingya survival rate in table 3 silver
Chlorophyll fluorescence kinetics technology is a technology based on photosynthesis theory, and it can provide abundant information for research spectrum and electron transfer process thereof, is the desirable technique that research plant photosynthesis physiological situation and Chilling stress coerce relation.Chlorophyll fluorescence kinetics technology can obtain the cold tolerance of plant different sites fast, with no damage, and this will provide a new shortcut for plant introduction and acclimatization and the cold resistant qualification of new variety and popularization.When plant is subject to environment stress, its Fv/F
0can show downtrending, fall is larger, shows that plant is coerced more serious, otherwise also can think that fall is less, then plant stress-resistance ability is stronger, therefore Fv/F
0fall can be used as the reliability index evaluating willow freezing tolerance.
After xylophyta survives the winter, as run into serious cold damage, then its terminal bud can not normally be sprouted, therefore terminal bud survival rate be reflection freezing tolerance of plant the most directly, the most reliable index.
Thus, known by table 3, Fig. 1 and Fig. 2, under low temperature stress, in silver, poplar chlorophyll fluorescence parameters shows decline in various degree, and wherein fall is minimum, and namely frost resistance is best, the terminal bud wintering rate of 13 groups is also the highest, and therefore the freezing tolerance of 13 groups is the strongest.
Experiment conclusion
The willow antifreezing agent adopting embodiment 1 to prepare and method of application enhance the freezing tolerance of blade, improve the wintering rate of willow terminal bud, add the adaptive faculty of willow to low temperature stress environment on the whole, filled up the market vacancy.
