Abstract
The invention discloses a method for improving the storage quality of autumn pears by using methyl jasmonate, which comprises the following operation steps: spraying the golden autumn pear fruits by using a methyl jasmonate solution of 10 mmol/L for 3 times respectively on the 10 th day, the 20 th day and the 30 th day before the golden autumn pear is harvested; after spraying, properly airing, and then bagging; selecting autumn pear fruits with consistent maturity and size and no mechanical injury or pest after harvesting, storing at room temperature, and regularly observing the V of the autumn pear fruitsCChange in weight loss rate and good fruit rate. The invention discovers that spraying methyl jasmonate solution of 10 mmol/L before picking can delay V in the storage processCThe content reduction, the weight loss rate increase and the rotting rate reduction are realized, so that the storage quality of the autumn pear fruits is improved, and a new method is provided for searching for a healthy and environment-friendly autumn pear preservative.
Description
Technical Field
The invention relates to application of methyl jasmonate in improving the storage quality of autumn pears, belonging to the technical field of fresh-keeping and storage of agricultural products.
Background
The fruit of the Jinqiu pear is larger than other fruits of the genus of the pear, the appearance color is ruddy, the edible quality is good, the Jinqiu pear is one of the most valuable varieties for planting the southern pears and has the reputation of southern pear king, however, the Jinqiu pear is easy to have various plant diseases and insect pests in long-time storage and transportation to cause the quality reduction of the fruit, such as appearance quality reduction, good fruit rate reduction, vitamin content reduction and the like.
Most fruit growers have inappropriate cultivation management technology for autumn pears, mostly adopt chemical agents to prevent and control plant diseases and insect pests, commonly use Bordeaux mixture, mancozeb, carbendazim, chlorothalonil and the like, and the chemical agents generally cause the fruits to generate resistance to the chemical agents and have chemical agent residues.
Disclosure of Invention
The invention aims to provide a method for improving the storage quality of autumn pears by using methyl jasmonate, and provides a new method for preventing the autumn pears from being corroded and preserving the autumn pears.
In order to achieve the purpose of the invention, the technical scheme of the invention comprises the following operation steps:
(1) spraying the golden autumn pear fruits by using a methyl jasmonate solution of 10 mmol/L for 3 times respectively on the 10 th day, the 20 th day and the 30 th day before the golden autumn pear is harvested;
(2) after spraying, properly airing, and then bagging;
(3) and storing after harvesting.
Test for improving the storage quality of autumn pears by methyl jasmonate:
selecting autumn pear fruits sprayed with methyl jasmonate solution, selecting autumn pear fruits sprayed with clear water as a control experiment, selecting the ripe degree and the size of the autumn pear fruits to be consistent after harvesting, cleaning the autumn pear fruits, airing, filling the autumn pear fruits into a fresh-keeping bag, ventilating a jack, storing at the temperature of 25 +/-2 ℃, and regularly observing the V of the autumn pear fruitsCChange in weight loss rate and good fruit rate.
Compared with the prior art, the invention has the beneficial effects that:
the application creatively discovers that spraying a methyl jasmonate solution of 10 mmol/L before picking can delay V in the storage processCThe content reduction and the weight loss rate increase, the good fruit rate and the rotting rate are improved, the storage quality of the autumn pear fruits is improved, and a new method is provided for searching for a healthy and environment-friendly autumn pear preservative.

FIG. 3 shows the effect of pre-harvest methyl jasmonate treatment on the fruit yield of autumn pears.
Detailed Description
The implementation place is as follows: guizhou province, Taijiang county, Taiwan town, four-step bridge golden autumn pear planting field.
Selecting 50 golden autumn pear plants with the same tree vigor and load capacity for testing. Spraying 10 mmol/L methyl jasmonate solution on single fruit every 10 days (27 days in 7 months, 6 days in 8 months and 16 days in 8 months in 2019) before picking for 3 times; when the methyl jasmonate solution is prepared, 0.05 percent of Tween80 is added to ensure that the solution is fully contacted with fruits, the fruits are properly dried after being sprayed, the fruits are preferably prevented from dripping, single-fruit bagging is carried out by utilizing a double-layer outer yellow inner black paper bag, the clear water spraying is used as a control experiment, and the size of the black paper bag is 160 mm multiplied by 198 mm.
And 8, 8 and 26 days in 2019, and harvesting autumn pear fruits. After harvesting, the fruits were stacked in plastic baskets with plastic foam cushions placed at the bottom and transported back to the laboratory. The golden autumn pear fruits with uniform appearance, namely, uniform maturity and size and no mechanical injury or pest and disease damage are selected for testing. The effect of improving the storage quality of the autumn pears by methyl jasmonate is observed.
Test for improving the storage quality of autumn pears by methyl jasmonate:
cleaning autumn pear, air drying, packaging into fresh-keeping bag, ventilating at jack, storing at room temperature of 25 + -2 deg.C, and periodically measuring VCWeight loss rate and good fruit rate.
The test results refer to fig. 1, 2, and 3.
Experiments show that the autumn pears sprayed with 10 mmol/L methyl jasmonate solution before picking are stored for 0 day, 4 days, 8 days, 12 days, 16 days, 20 days, 24 days and 28 days after picking, and compared with control treatment, the average V isCThe content is increased by 1.55 mg/100g, 0.48 mg/100g, 1.72 mg/100g, 1.91 mg/100g, 2.21 mg/100g, 2.08 mg/100g, 2.46 mg/100g and 1.8 mg/100g respectively. Day 4, 8, 12, 16, 20, 24, 28, compared to control treatment,the weight loss rate is respectively reduced by 0.42%, 0.58%, 0.55%, 2.01%, 2.99%, 3.28% and 3.34%. On the 47 th day, the fruit yield is improved by 22.22% compared with the control.
V can be delayed by methyl jasmonate treatment before harvestCThe content is reduced, the weight loss rate is increased, the good fruit rate is improved, and the rotting rate is reduced.
