光质 meaning in English
light quality
Examples
- The error caused by the photoperiodic induction changes along with the initiatory and terminative radiation level . and the effect of photosynthetic oscillations should be emphasized in fast measurement of photosynthesis
在诱导期间(光诱导期或光合振荡期)进行光合速率测定造成的误差与叶片光环境变化前后的强度水平及光质有关。 - Inversely , when kt was present in the medium the light induced inhibition was also decreased . it is an independent process of light and kt on inhibition of hypocotyl elongation and they showed multiplication effect on the process
不同光质下可降低kt对下胚轴伸长的抑制效应；反之， kt的存在也降低了不同光质对下胚轴伸长的抑制作用。 - 4 effects of light quality and kt on anthocyanin accumulation 2 - d - old wl grown seedlings were irradiated with continuous wl , rl , fr , bl and uv - b , respectively , for 3 d and the accumulation of anthocyanin was detected
四、光质和kt对花色素苷积累的作用白光、蓝光、紫外光b 、红光和远红光等不同光质处理2天龄白光下生长的幼茧， 3天后测定花色素昔含量。 - 2 effects of light quality and kt on hypocotyl elongation the hypocotyl elongation of 2 - d - old etiolated seedlings was inhibited evidently under continuous light including uv - b , wl , bl , fr and rl . the inhibition effectiveness was uv - b > wl > bl > fr > rl
二、光质和kt对下胚轴伸长的影响不同光质持续照光对2天龄黄化下胚轴伸长有明显的抑制，不同光质对伸长抑制的效应表现为uv - b wl bl fr rl 。 - When the change of radiation environment has instantaneous change , the photosynthetic rate ca n ' t reach the rate that it should be in the changed situation . that is called the photoperiodic induction . usually the time of the photoperiodic induction is from 3 minute to 8 minute
当叶片所处光环境的光强和光质发生瞬时变化后叶片光合速率通常都要经过3 8分钟适应才能达到变化条件下应有的光合速率值。
