Chlorin iron (iii) chelate with plant growth regulating activity and its application as plant growth regulator

Abstract

The invention discloses dihydroporphin (III) chelates having plant growth regulating activity and use thereof as plant growth regulators. The respective structures of the chelates are shown below. In the structures, R may be H, Na, K, CH3 or C2H5, and X may be Cl, OCOCH3 or OH. The dihydroporphin (III) chelates are formed by chelating pyropheophorbide, purpurin and dihydroporphin serving as main ligands and different acid radicals and hydroxy radicals as axial ligands (X) with trivalent ions of iron serving as a transitional metal. The dihydroporphin (III) chelates serving as plant growth regulators are safe, nontoxic and insusceptible to accumulation of residue; the activity of the dihydroporphin (III) chelates are high and the effect of the dihydroporphin (III) chelates are remarkable; and the dihydroporphin (III) chelates can improve the chlorophyll content in plants, promote rooting, and increase germination rate, resistance and yield.

Description

technical field [0001] The invention relates to a plant hormone, in particular to a safe and efficient chlorinated iron (III) chelate (structural compound) with plant growth regulating activity, and the chlorinated iron (III) chelate III) Application of chelates in the preparation of plant growth regulators. Background technique [0002] In the process of plant growth, trace physiologically active substances play an important role in the growth of plants, just like sunlight, temperature, water and other nutrients. These trace active substances have a special effect on regulating the growth and development of plants. Various endogenous trace active substances are often called plant hormones, such as auxin, gibberellin, cytokinin, etc., while non-endogenous external active substances are called plant growth regulators. Most of the currently used plant growth regulators are artificially synthesized compounds. In recent years, some products have been found to have varying degre...

Chinese patent ZL200610097240 discloses a known porphyrin structural extract hemin (Hemin, also known as porphyrin iron, hematoporphyrin, hemin, heme) derived from animals as a plant growth regulator application, heme has excellent plant growth regulating activity, but limited by the source of animal extracts, high cost, poor solubility (almost insoluble in water), photothermal instability, and easy decomposition of products, these unfavorable special properties increase The technical difficulty of the practical application and promotion of heme

In fact, there are no reports about chlorophyllase inhibitors and their related application research.
