Embodiments of the present disclosure describe diapocarotenoid plant growth regulators represented by formula (I): R-A-R (I) or a precursor, salt, solvate, stereoisomer or polymorph thereof; wherein R is a monovalent carbonyl moiety selected from the group consisting of aldehydes, ethers, diethers, carboxylic acids, alcohols, and ester carboxylates and A is a bivalent polyene represented by the bivalent moiety -(CRa=CRb)x- wherein x is the number of double bonds in polyene moiety A, and Ra and Rb are, independently, hydrogen, a hydrocarbon, or an alkoxy group, and composition of the diapocarotenoid plant growth regulators in an agronomically acceptable carrier. Methods of regulating plant growth including promoting root development, increasing nutrient uptake, enhancing resistance to abiotic stress factors, invigorating plant growth, increasing plant yield, and increasing plant biomass by applying at least one diapocarotenoid plant growth regulator to a seed, plant propagation material, plant or plant growth medium are also described.
本公开的实施例描述了由公式(I)表示的二缩醛类胡萝卜素植物生长调节剂:R-A-R(I)或其前体,盐,溶剂,立体异构体或多形体;其中R是单价羰基基团,所选自醛,醚,二醚,羧酸,醇和酯羧酸酯的群体,而A是由双价多烯表示的双价基团,该双价基团由-(CRa=CRb)x-表示,其中x是多烯基团A中双键的数量,而Ra和Rb是独立的氢,烃基或烷氧基。将二缩醛类胡萝卜素植物生长调节剂与农学上可接受的载体混合的组合物也被描述。还描述了通过将至少一种二缩醛类胡萝卜素植物生长调节剂施用于种子,植物繁殖材料,植物或植物生长介质来调节植物生长的方法,包括促进根系发育,增加养分吸收,增强对非生物胁迫因素的抵抗力,激发植物生长,增加植物产量和增加植物生物质。
