Problems solved by technology

However, complex cultivation and management measures are not easy to be mastered by the masses, and plant growth regulators such as spraying ethephon often cause the peak of fruit respiration to come earlier, reduce the post-harvest storability of fruits, and shorten the shelf life

example 3

[0018] Example 3. In mid-January, 2005, strawberries in the white ripening period (the variety is 'Fengxiang') were picked from Fujiabian Orchard in Lishui, Nanjing, and the fruit was smeared with different concentrations of GNT, and then directly placed in a light intensity of about 180 μmol m -2 ·s -1 In the ecological incubator, the light was continuously illuminated for 24 hours. The results showed that the anthocyanin content of dark-treated strawberry was 1.27nmol / gFW, and that of light-treated fruit was 1.49nmol / gFW, and there was no significant difference. The anthocyanin contents of fruits treated with 5.5-22 mg / L GNT increased to 3.15, 3.86 and 5.96 nmol / gFW, which were significantly higher than the light control without GNT treatment (Table 3).

[0019] Example 4. In mid-June, 2005, nectarine (No. 5 Zhongyou) fruit was smeared with different concentrations of GNT, and then placed in a light intensity of about 180 μmol m -2 ·s -1 In the ecological incubator, the l...

example 5

[0020] Example 5. In June 2005, the extremely early-maturing apple Tianhuangkui was used as the material to study the effect of 11-33mg / L GNT on the synthesis of anthocyanins in the pericarp. The results showed that the anthocyanin content of the apple pericarp preserved in the dark was 4.92nmol / cm 2 , while under weak light (60μmol·m -2 ·s -1 ) The anthocyanin content of the lower pericarp is 5.75nmol / cm 2 , if pre-treated with 11-33mg / L GNT, it rises to 6.3-6.61nmol / cm 2 , 10-15% higher than the light control. In weaker light (160μmol·m -2 ·s -1 ), the light control fruit is 5.83nmol / cm 2 , while GNT treated fruit was 6.42-7.26nmol / cm 2 , which is 10-25% higher than the light control (Table 5), indicating that GNT has a significant promoting effect on the synthesis of anthocyanins in extremely early ripening apples. After the treatment of GNT, the colored parts such as red stripes and red slices appeared in the fruit.

example 6

[0021] Example 6. In June 2005, plums were used as materials, and the fruit was soaked with different concentrations of GNT for 3-5 seconds, placed in 160μmol·m -2 ·s -1Under light conditions, the anthocyanin content of the pericarp was analyzed after 48 hours, and it was found that the light control pericarp was 3.15nmol / cm 2 , while the 11-33mg / L GNT treatment fruits were 3.54, 3.60 and 3.68nmol / cm 2 , about 12% more than the control (Table 6).

Abstract

The invention relates to a new method for promoting the fruit coloring, private for fruit coloring. Spraying 10-40mg/l cytisoside containing 0.1% broad adhesive on the fruit surface, and one time is ok before the fruit matures, or immersing the fruit with 10-40mg/l cytisoside containing 0.1% broad adhesive for 3-5 s after harvesting the fruit, drying in the dark and keep for 12 h, then exposing the fruit to the artificial light source or sunlight for 3-5 days for coloring. The method can be used for coloring fruit such as apple, pear, peach, plum, apricot, grape and strawberry which cultivated with bag covered or without bag covered. The method is simple, high effective, fast and safe, improves the fruit coloring degree and apparent quality.

Description

1. Technical field [0001] The invention relates to a new method for promoting fruit coloring, which is specially used for promoting plant fruit coloring. 2. Technical Background [0002] Genistein (GNT) is a plant isoflavone substance extracted from soybeans that has a mild estrogenic effect on animals, also known as 5,7,4'-trihydroxyisoflavone or genistein Genistein or genistein, its full chemical name is 4′, 5, 7-Trihydroxyisoflavone 5, 7-dihydroxy-3(4-hydroxyphenyl)-4H-1-benzopy-ran-4-one, and its chemical structure is as follows: [0003] [0004] Genistein Chemical Structural Formula [0005] People developed and utilized GNT, which was first used to supplement estrogen deficiency in menopausal women and relieve menopausal symptoms, such as "Mrs. Oral Liquid". In recent years, people have found that it not only has the effect of removing cell peroxidation products and preventing osteoporosis in menopausal women, but also has the functions of anti-cancer, anti-cance...
