A clear correlation was found between the growth of mutant forms of pea plants and the light intensity: With an increase in the latter the growth of the plants was inhibited and the rate of photosynthesis increased. The inhibitory action of light on stem growth affected not only tall pea plants, but also dwarf forms. A definite link was observed between the genetic apparatus and the balance of endogenous phytohormones and inhibitors. The content of bound forms of gibberellins was directly related to the growth intensity--the content of these substances was highest in the tall Torsdag pea plant, it was lower in the semidwarf K-29, and it was very low in the dwarf K-202. The content of quercetin glucosylcoumarate was lowest in Torsdag pea plants, in dwarf mutants the greater the amount of this compound the shorter the stem. The genetically determined ratio of phytohormones and inhibitors in the original tall and dwarf forms of pea plants is retained under all illumination conditions at various intensities.
随着光照强度的增加，植株生长受到抑制，光合作用速率提高。光照对茎生长的抑制作用不仅影响高茎豌豆植株，也影响矮化植株。在遗传机制与内源植物激素和抑制剂的平衡之间观察到了明确的联系。赤霉素结合形式的含量与生长强度直接相关——这些物质的含量在高茎托尔施达格豌豆植株中最高，在半矮化的K - 29中较低，而在矮化的K - 202中非常低。槲皮素葡萄糖基香豆酸酯的含量在托尔施达格豌豆植株中最低，在矮化突变体中，这种化合物的含量越高，茎越短。在不同强度的所有光照条件下，豌豆植株原始高茎和矮化形式中由基因决定的植物激素和抑制剂比例保持不变。
