Structural organization of leaf for introduced species of Kalanchoe in protected ground conditions

Abstract

The investigation of morphological and anatomical structure of leaves for some species of section Bryophyllum have discovered the character of adaptability to the aride growth conditions. The original specialization in structure of leaves is distinguished for Kalanchoe beauverdii Hamet and K. tubiflora (Harvey) Hamet. The formation of almost cylindric photosynthetic elements of these species originates on different morphological bases. The bifacial leaf phylloids of K. tubiflora are analogous to linear bifacial and equifacial leaves of K. beauverdii. The nonstandard inverting development of specialized photosynthetic mesophill is observed in anatomical structure of leaf for these species. Such type of the leaf organization is an attribute of the most specialized types of succulent leaves.
