The contents of gibberellin-like substances in lettuce seeds were determined. In darkness the seeds contain only small amounts of gibberellin-like substances, but upon illumination with near red light there is a sharp increase in the gibberellin content within one hour. It is concluded that lettuce seeds in darkness do not contain the amounts of gibberellin necessary for germination and that under the influence of light these amounts are provided.
测定了生菜种子中类赤霉素物质的含量。在黑暗中,种子仅含有少量类赤霉素物质,但在用近红光照射后,一小时内赤霉素含量急剧增加。得出的结论是,黑暗中的生菜种子不含有萌发所需的赤霉素量,而在光照的影响下会提供这些量。
