The main results are as follows : 1 effects of light quality and kt on cotyledon enlargement 5 - d - old seedlings of arabidopsis wild type and mutants were harvested and the cotyledons were cut to use as excised cotyledon or the whole seedlings were used as intact cotyledon. excised and intact cotyledons were incubated in the medium ( ph 6. 0 ) with or without kt under white light ( wl ), red light ( rl ), far - red light ( fr ) and uv - b at 21 ? ? for some periods of time before cotyledon area were determined by a delta - t area measurement system
主要結果如下：一、光質和ky對于葉擴大的影響白光、紅光、藍光明顯促進5天齡幼苗離體和連體子葉擴大，遠紅光對子葉的擴大效應較弱， uv - b對子葉的擴大有抑制；對突變體的研究表明，紅光下光敏色素b 、遠紅光下光敏色素a 、藍光下隱花色素1對子葉的擴大起主要調節作用。
