Morpho-physiological features of Stephanotis floribunda inconditions of greenhouse culture

Abstract

Stephanotis floribunda Brongn. is an ornamental pot-plant characterized with intensive growth, profuse flowering, stability in interior conditions. We studied the growth and developmental rhythm of the shoot system of the experimental plant, investigated its biomorphological features, compared the physiological and biochemical characteristics of the assimilating organs of Stephanotis floribunda during the growing season in phases: budding, mass flowering, flowering end, single flowering, slow growth and relative peace. The system of stephanotis shoots is characterized by a plagiotropic growth direction and all its vegetative-generative areas are structurally homogeneous. Due to its ability to take root in each node, the structural unit – metamer – retains autonomy and is able to restore the entire individual. The indicators of the pigment composition throughout the whole observation period indicate the stability of the photosynthetic system, and confirm the significant adaptation potential of Stephanotis floribunda in protected ground conditions.
