摘要: Abstract Stem elongation of young plants Capsicum annum L., Dendranthema grandiflora Ramat., Euphorbia pulcherrima Wild & Klotsch, Pelargonium × hortorum L.H. Bailey, Petunia hybrida and Salvia splendens was continuously measured under long-day (LD) short-day (SD) conditions with a high degree resolution, using linear voltage differential transducers greenhouse conditions. A stem rate (SER) during the scotoperiod low SER photoperiod found in Capsicum, . In did not show large differences between photo- while largest photoperiod. There no distinct difference pattern LD compared SD conditions, nor particular which could be connected to photoperiodic requirement plants.
