The ‘end‐of‐day’ phytochrome control of internode elongation in mustard: kinetics, interaction with the previous fluence rate, and ecological implications

摘要: In the experiments reported here we monitored extension growth of first internode light-grown mustard seedlings in darkness after pulses which provided different Pfr/p. The interactions between Pfr/P and PAR levels at plants were grown, was also investigated as latter had previously been shown to modify extent several responses end-of-day pulses. Finally, compared, over same period darkness, efficacy a reduction end continuous WL with that similar during or hours dark transition
