摘要
随着光照强度的降低,红檵木成熟叶中叶绿素a的含量上升,新叶的叶绿素a含量先上升后下降;叶绿素b含量都呈现先上升后下降的趋势;新叶中类胡萝卜素的含量先上升后下降,成熟叶的类胡萝卜素大体呈上升趋势;成熟叶的叶绿素含量大体上升,而新叶的叶绿素含量则先上升后下降。光照强度降至8000 lx的过程中,a/b值明显下降;花色素苷含量随光照强度的降低而降低。
As photoperiod decreased, the chlorophyll a in the mature leaf content increased, but in the new leaves chlorophyll a content increased fhst , and then decreased; the chlorophyll b content increased first , and then decreased; In the new leaves the kind of anthocyanin content increased first , and then decreased, in the mature leaf , the anthocyanin inereaaed; The mature leaves＇ chlorophyll content increased roughly, but new leaves＇ chlorophyll content increased first , and then decreased. On the process of the photoperiod falls to 80001x, a/b drops obviously; The anthecyanin content decreased along with the strength of illumination decreased.
