栽培在不足光照条件下的番茄,直接在花序上外用(艹卡)腺嘌呤(BA)与赤霉素(GA)以促进其发育,这两种化合物在控制花序发育上有后效,BA的作用首先发挥,而GA仅跟随在BA作用之后。GA_(4+7)在与BA混合时,较GA_3促进花序发育更为有效得多,测定花序中碳水化物含量表明,在生长物质处理期,可溶糖类及淀粉水平暂时增加。研究不同植物部分之间的干物质分配表明,生长物质改变植物体内同化物质的分配模式,在以其上幼叶为代价的情形下,对花序是有利的。番茄栽培于不足光照条件下,花序的发育因限于花序局步施用生长物质而大为加强,BA和GA_3同时施用特别有效。因此,应用这些化学品实际上是有效的。特别在冬季,通常由于光照条件不足,花序发育不全。
Tomatoes grown under deficient light conditions were topically applied with adenosine (BA) and gibberellin (GA) on their inflorescences to promote their development. Both of these compounds had post-treatment effects on controlling inflorescence development, and BA The role played first, while GA only followed BA’s role. GA 4 (4 + 7) was more effective than GA 3 in accelerating inflorescence development when mixed with BA. The determination of carbohydrate content in inflorescence showed that the soluble sugars and starch temporarily increased during the growth phase. Studying dry matter partitioning between different plant parts suggests that the growth pattern alters the pattern of assimilation of the assimilation material in the plant and is beneficial to the inflorescence at the expense of its young leaves. Tomato cultivated in the condition of insufficient light, the development of inflorescence was greatly strengthened because of the inflorescences applied to the growth material, and the simultaneous application of BA and GA_3 was particularly effective. Therefore, the application of these chemicals is actually effective. Especially in winter, inflorescences are usually underdeveloped due to insufficient light conditions.
