单词 long-day plant
释义

long-day plant


long-day plant

[′lȯŋ ¦dā ‚plant] (botany) A plant that flowers in response to a long photoperiod.

long-day plant


long-day plant

one that requires a day length exceeding a certain minimum value for the induction of flowering to take place. In fact, the term is somewhat misleading in that such plants (e.g. lettuce, clover) are really sensitive to periods of darkness rather than daylight, requiring a night length of no more than a maximum duration, i.e. these are short-night plants. Compare SHORT-DAY PLANT, DAY-NEUTRAL PLANT. see PHYTOCHROME.
