A kind of fruit-inducing colorant composition

Abstract

A fruit induction coloring agent composition is prepared from, by weight, 1-3 parts of natural abscisic acid, 18-22 parts of isopentennyladenine with the mass content being 0.02%, 9-12 parts of ammonium molybdate, 38-42 parts of citricacide-titanium chelate, 18-22 parts of glycine, 1-3 parts of n-propyl dihydro-jasmonate and 6-10 parts of monopotassium phosphate. The composition does not contain ethephon and has no side effects like threshing and leaf falling; in the fruit swelling stage, fruits quickly swell, the fruits can be quickly colored within one week in the early stage of fruit coloring, the sugar degree is increased, the natural anthocyanin content is increased, the fruits can come into the market 7-10 days earlier, quality of fruits processed by a fruit induction coloring agent is improved, storage and transport performance is improved, photosynthesis can be enhanced, the chlorophyll content is increased, activity of peroxidase is improved, and absorption and transport of plants to nitrogen, phosphorus, potassium and other microelements are promoted.

Description

[0001] Technical field: The present invention relates to a medicament capable of promoting the coloring induced during fruit growth, in particular to a fruit-induced colorant composition. Background technique: [0002] Plant growth regulators are a class of substances that have similar physiological and biological effects to plant hormones. Substances that have been found to regulate plant growth and development are: diethyl diethylhexanoate, forchlorfenuron, sodium nitrophenolate, auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinosteroids, salicyl acid, jasmonic acid, paclobutrazol and polyamines, etc. Plant growth regulators have many uses, which vary by variety and target plant. [0003] At present, the research on the application of fruit coloring mainly focuses on plant growth regulators such as ethephon and abscisic acid. [0004] Ethephon is a high-quality and high-efficiency plant growth regulator, which has the effects of promoting fruit ripening, stim...

Problems solved by technology

Using abscisic acid alone and spraying directly on grapes, apples and other fruits can specifically promote the formation of anthocyanins in the peel and effectively promote coloring. However, it is found that grapes, apples and other fruits color quickly, but the sugar accumulation is relatively low. Slow, resulting in beautiful but not sweet fruits; in addition, abscisic acid is sensitive to light, unstable and easy to decompose during use, such as natural abscisic acid (D-type S-ABA), which will be decomposed or isomerized into L-type abscisic acid ( R-ABA), studies have shown that R-ABA activity is 3 to 5 times weaker than S-ABA activity

Although compounds such as sodium indolebutyrate, brassinolide, and levulinic acid have the function of coloring, they are also likely to cause the early arrival of the fruit's respiratory peak, reduce the subsequent storability, and shorten the shelf life; while colorant fertilizers The coloring effect is not obvious, and it takes a long time for coloring

[0006] In order to improve the quality of the fruit, make the color of the fruit even, bright and sweet, increase the sweetness, prevent fruit threshing, and fruit intolerance to storage, etc., it is necessary to study an easy-to-use, stable effect, long-lasting effect, no threshing, Fruit-inducing colorants with side effects such as defoliation
