Abstract
The invention discloses a composition capable of improving stress resistance of hybrid liriodendron body embryo seedlings and realizing a promoting effect. The composition is prepared from 5 to 10 parts of wheat germ agglutinin, 5 to 10 parts of peanut agglutinin, 5 to 10 parts of sodium lignosulphonate, 5 to 10 parts of high-dispersion silicic acid, 10 to 20 parts of sodium dodecyl sulfonate and70 to 140 parts of kaolin. According to the composition disclosed by the invention, massive experiments are conducted for screening; the wheat germ agglutinin and the peanut agglutinin of which the weight ratio is 1 to 1 are creatively adopted as main active ingredients and matched with the sodium lignosulphonate, the high-dispersion silicic acid, the sodium dodecyl sulfonate and the kaolin with optimal use amounts. Experimental results show that the composition provided by the invention has the beneficial effects that the resistance of the hybrid liriodendron body embryo seedlings to adversetemperature environments of 4 DEG C low temperature and 40 DEG C high temperature is remarkably enhanced, and the drought resistance of the hybrid liriodendron body embryo seedlings can be obviously improved. The composition disclosed by the invention has the advantages of scientificity and reasonability in component matching, greenness, environmental protection, low toxicity and important practical application value.
Description
technical field [0001] The invention relates to an agricultural preparation, in particular to a composition capable of improving stress resistance and growth-promoting effect of somatic embryo seedlings of Liriodendron chinensis and application thereof. Background technique [0002] Liriodendron is a broad-leaved tree widely distributed in southern my country. Its fast-growing, high-quality materials, and high industrial value make it an important timber tree species. The hybrid bred by crossbreeding Chinese mandarin tree and North American Liriodendron as parents Liriodendron has the advantages of straight trunk and rapid growth. In order to further expand the popularization and application of Liriodendron hybridum, it is necessary to carry out biological research on the response of Liriodendron hybridum to extreme temperature stress. [0003] One of the early events in plant response to temperature stress is the excessive accumulation of reactive oxygen species. Excessive...
