Description
Technical Field
The invention belongs to the technical field of plant cultivation, and relates to a method for inhibiting axillary buds of glutinous rice cake litchis from being light and application thereof.
Background
Glutinous rice cake litchi is used as a high-quality main cultivation variety in south China and is mainly widely planted in Guangdong, guangxi, hainan provinces and the like in China. Because of good flavor and nutrition, the beverage is popular among the public. However, the phenomenon of the glutinous rice cake litchi of the size of year is serious due to the influence of the growth and development characteristics and bad weather of the glutinous rice cake litchi, and the high-quality sustainable development of the glutinous rice cake litchi is greatly restricted. The reason is closely related to the fact that the branches of the fruiting parent branches of the glutinous rice cake litchis are too many and the branches are weak. The glutinous rice cake litchi is subjected to shoot pulling for many times within one year, and when new shoots are pulled and light, axillary buds are pulled and light too much, so that multi-branch fruiting parent branches are formed, and further the flower quality, the fruit growth and development and the mature quality are affected. In addition, branches are more likely to cause diseases and insect pests caused by tree body depression, so that the management and production cost is greatly increased. How to culture the strong fruiting parent branch with less branches is an important countermeasure for solving the problem of 'size and year' of the glutinous rice cake litchi.
At present, in the cultivation and production of the glutinous rice cake, the thickness of the fruiting parent branch is often improved through tip killing, root breaking, girdling and shaping pruning, the quality of the fruiting parent branch of the glutinous rice cake litchi can be improved to a certain extent by applying the technologies, but the axillary bud is not well inhibited from being extracted and generated, and the axillary bud can still be extracted to form a branch to form a multi-branch fruiting parent branch; in addition, the current technology has large labor capacity, greatly increases management and production cost, and is not sustainable with the situations of 'labor waste and difficulty' as the population ages.
Plant hormone has a very complex network structure in the process of regulating axillary bud extraction, and early reports mainly focus on auxins and cytokinins. Strigolactone is a generic term for some natural strigolols and their artificially synthesized analogues or derivatives. The earliest strigolactone was Strigol (Strigol), isolated from the rhizosphere secretion of cotton, a non-host plant of strigola, by Crook in 1966, and was able to induce seed germination in strigola, broomrape, etc., and was subsequently found in other plants such as corn, sorghum, millet. Synthetic strigol analogs were reported by Johnson et al in 1976, as having GR (germination releaser) series such as GR24, GR7, GR3, etc. The GR24 activity is highest, and is the most common strigolactone compound used by scientific researchers at home and abroad at present.
However, no research report on inhibiting the axillary bud of the glutinous rice cake litchi by strigolactone is provided at present, and a method for inhibiting the axillary bud of the glutinous rice cake litchi is provided, so that a new efficient and labor-saving way for improving the fruit quality in agricultural production is provided.

Detailed Description
The following disclosure provides many different embodiments, or examples, for implementing different aspects of the invention.
The invention aims to overcome at least one defect of the prior art and provides a method for inhibiting axillary bud light emission of glutinous rice cake litchi and application thereof.
The technical scheme adopted by the invention is as follows:
the invention provides a method for inhibiting axillary buds of glutinous rice cake litchi, which is to treat glutinous rice cake litchi plants exogenously by strigolactone solution.
Strigolactone is a generic term for natural strigolols and synthetic analogues. The compound has the same structural framework and is formed by connecting hexakispentakis-pentacyclic lactone with gamma-butenolide through enol ether linkage. The strigolactone adopted by the invention is an artificially synthesized analogue GR24 of strigolactone, and the molecular formula is C 17 H 14 O 5 Is a chemical substance which is artificially synthesized on the basis of taking strigolactone Strigol as a framework.
The molar concentration of strigolactone in strigolactone solution adopted by the invention is 20 mu M, and the invention also comprises the following components in volume ratio: 0.08% Tween-20,0.3% acetone, and the balance being water.
The treatment part of the glutinous rice cake litchi is axillary buds, the dosage of strigolactone solution is 19.5-20.5 mu L/plant, the axillary buds are dripped and treated 1-2 weeks before the terminal buds of the glutinous rice cake litchi plant sprout, and the glutinous rice cake litchi plant is treated 1 time per day.
Examples
(1) Configuration of GR24 mother solution: 5mg of the artificially synthesized strigolactone analogue GR24 was accurately weighed, and 0.3% acetone and 1676. Mu.L of pure water were added to dissolve to 10mM of mother liquor, which was stored in a refrigerator at-20 ℃. The mother liquor was diluted to 20. Mu. MGR24 working solution at the time of use.
(2) GR24 treatment: according to the treatment position diagram of FIG. 1, 3 lines of glutinous rice cake litchi with similar growth vigor are randomly selected one week before the terminal buds of glutinous rice cake sprout, and 0.08% Tween-20 and 20 mu M GR24 working solution after dilution are added.
Comparative example
Comparative example pure water containing 0.08% Tween-20 and 0.3% acetone was used as a control group, and the treatment was carried out 1 time per day using a disposable head dropper for 7d, and the treatment was carried out in a working solution amount of 20. Mu.L for each treatment, in order to suspend the liquid droplets on the axillary buds.
Experimental results
The effect of the post-treatment (1, 5,7, 14 d) is shown in FIG. 2. The exogenous GR24 treatment obviously inhibits the germination of the axillary buds of the glutinous rice cake after 5d treatment compared with the Control (Control); after treatment for 7d, the control axillary buds had begun to light, whereas the GR24 treated axillary buds had only the initial swelling. After 14d, the control glutinous rice cake axillary buds had been completely extracted as lateral branches, while the GR24 treated axillary buds still showed enlarged status.
Axillary bud extraction rate statistics after GR24 treatment: after GR24 treatment and control treatment, the three-dimensional culture of 3 'glutinous rice cake' litchis was counted from time nodes of 0d, 3d, 5d, 7d and 9d of day of treatment. As shown in FIG. 3, quantitative analysis showed that the axillary bud extraction rate of the 7d control group 'nuomici' reached 80%, while the extraction rate after GR24 treatment was only 15%.
In conclusion, the GR24 reagent is dripped on the external source of the glutinous rice cake litchi, so that the axillary buds of the glutinous rice cake litchi can be effectively inhibited from being extracted, and the aging is inhibited for half a month.
The above description of the present invention is further illustrated in detail and should not be taken as limiting the practice of the present invention. It is within the scope of the present invention for those skilled in the art to make simple deductions or substitutions without departing from the concept of the present invention.
