daylength 中文意思是什麼

daylength 解釋
晝長
  1. Seedlings were treated with different daylengths and with different numbers of photoperiods. the results showed that treatments with short day - lengths promoted its flowering and the critical daylength is 15h

    不同日照長度處理：對畢氏海蓬子植株分別施以每天光照6h ? 16h ，間隔為1h的不同日照長度處理，從而確定其臨界日長； 2
  2. Effects of daylength and temperature on the spike differentiation of winter wheat

    光溫生態因子對冬小麥幼穗分化的影響研究
  3. Plants treated with daylengths not longer than 15h flowered earlier with the shortening of the daylength. plants flowered earliest when treated with 8h light / d

    在8h光照16h黑暗處理條件下，畢氏海蓬子開花所需之臨界光周期數為13 ； 3
  4. All above indicates that short daylength promoted flowering in salicornia bigelovii torr. on the contrary, long daylength inhibited both its floral induction and development of post - flowering

    畢氏海蓬子的花器官發育具有與誘導同樣的光周期要求，均為短日照，屬于kniet分類中的第一種類型。
  5. Both the floral inducti on and the development of flower organ in salicornia bigelovii torr. needed short daylength. the flowering reversion is maybe in relation to the insufficient quality of flowering substances and the flowering habit of salicornia bigelovii torr.

    畢氏海蓬子的成花逆轉現象可能與植株體內開花刺激物數華氏蛤么谷升龍的允用們技寇的研充量和植物的開花習性有關。
  6. The promotion effects is stronger with the increase of number of photoperiods, which suggests that the flowering process in salicornia bigelovii torr. is not a " all or none " process. treated with 13 - 18 photoperiods and then transposed to long - daylength ( 17h light / d ), some of the inflorescences of the plants reversed to vegetative condition, which means flowering reversion occurred ( which belongs to inflorescence reversion type )

    畢氏海蓬子開花的臨界日長為15小時，濟南地區最大晝長在6月23日，為14小時40分，並沒有超過其臨界日長，但處于自然日照條件下的畢氏海蓬子直至7月25日才形成花序，在此之前一直處于營養生長狀態，可能這個階段是成花物質積累的階段，當成花物質數量積累足夠多時，才可促進花序形成和導致開花。
