多效唑在农业、植物组织培养中的应用及其作为逆境改良剂的潜力综述

收到11/9/2021;PAClObutRAzOl (Pbz)是一种植物生长调节剂，是三唑类化合物的一种，可以阻止生长发育激素(赤霉素)的生物合成。Pbz还被用于减少冠层体积和增加许多作物的开花强度。PBZ可以缩短株高，增加茎粗和叶片数量。Pbz还可用于控制开花和坐果。PBZ效率是植物组织培养中最重要的抑制物质之一，它可以减缓植物的生长，减少继代培养的数量。此外，Pbz已被广泛应用于体外抑制生长和诱导开花。另一方面，大量研究证实了Pbz对植物对不同非生物/生物胁迫的耐受性/抗性的促进作用。但不同环境区室中Pbz的生态毒理学研究还有待进一步深入。此外，在生物胁迫下，Pbz对高温干旱或干旱盐胁迫下栽培植物的影响还有待进一步研究。
