这是对经典的和新的、天然的和合成的植物激素和生长调节剂(植物激素)的简短回顾，并强调了它们在植物组织培养中的一些用途。植物激素很少单独起作用，对于大多数过程--至少在器官水平上观察到的过程--这些调节因子中的许多都相互作用，以产生最终效果。讨论了以下物质：(A)经典的植物激素(生长素、细胞分裂素、赤霉素、脱落酸、乙烯和具有类似生物学作用的生长调节物质)。这些类别中的新的、自然存在的物质仍在被发现。与此同时，新的结构相关的化合物也在不断地被合成。也有许多新的但化学上无关的化合物正在产生，它们具有类似激素的活性。更好地了解植物激素的吸收、运输、代谢和作用方式，以及抑制本地植物激素合成、运输和作用的化学物质的出现，增加了我们对这些激素在生长和发育中作用的了解。(B)最近发现的具有植物激素样调节作用的天然生长物质(多胺、低聚糖精、水杨酸酯、茉莉酸酯、甾醇、油菜素类固醇、脱氢二异甘油醇葡萄糖苷、Turgorins、系统素、无关的天然刺激剂和抑制剂)以及肌醇。这些生长活性物质中的许多还没有在体外与生长和组织发育相关的研究。
This is a short review of the classical and new, natural and synthetic plant hormones and growth regulators (phytohormones) and highlights some of their uses in plant tissue culture. Plant hormones rarely act alone, and for most processes— at least those that are observed at the organ level—many of these regulators have interacted in order to produce the final effect. The following substances are discussed: (a) Classical plant hormones (auxins, cytokinins, gibberellins, abscisic acid, ethylene and growth regulatory substances with similar biological effects. New, naturally occurring substances in these categories are still being discovered. At the same time, novel structurally related compounds are constantly being synthesized. There are also many new but chemically unrelated compounds with similar hormone-like activity being produced. A better knowledge of the uptake, transport, metabolism, and mode of action of phytohormones and the appearance of chemicals that inhibit synthesis, transport, and action of the native plant hormones has increased our knowledge of the role of these hormones in growth and development. (b) More recently discovered natural growth substances that have phytohormonal-like regulatory roles (polyamines, oligosaccharins, salicylates, jasmonates, sterols, brassinosteroids, dehydrodiconiferyl alcohol glucosides, turgorins, systemin, unrelated natural stimulators and inhibitors), as well as myoinositol. Many of these growth active substances have not yet been examined in relation to growth and organized developmentin vitro.
