Abstract
The aim of the present study is to determine the micro-morphological properties of the leaf surfaces of nine species belonging to the family Chenopodiaceae, using scanning electron microscopy (SEM). Leaf surfaces were noticed to vary considerably with respect to cuticle structural types, stomatal pores position, guard cells cuticular ledges and types of trichomes. Lamellate and lamellate-reticulate cuticular types were recognized. These cuticular folds undergo various patterns, depth and orientation in the various species examined. Sunken, ridged, leveled, raised or depressed stomatal pores were encountered, whereas, the guard cells ledges were poorly or well- developed. In Suaeda vermiculata the stomatal pores are sunken in high longitudinal folds rendering the ledges indistinct. Non-glandular unbranched trichomes were detected in Bassia muricata, and collapsed salt bladders were reported in Atriplex leucoclada. The results showed that the micro-morphological characters of the leaf-surfaces examined are considered to be adaptations in response to arid conditions.
Highlights
Plant surfaces micro- and nano-structures are diverse (Koch et al 2008), and are evolved in response to their interaction with the environment (Barthlott et al 2017)
The leaf surfaces of various members of the family Chenopodiaceae were previously examined by scanning electron microscopes (SEM)
The spread area of herbicidal droplets of Chenopodium album was analyzed by Sanyal et al (2006), whereas the effect of emitted dust particles on the distribution of Atriplex leucoclada was investigated by Oran & Al Zoubi (2016)
Summary
Plant surfaces micro- and nano-structures are diverse (Koch et al 2008), and are evolved in response to their interaction with the environment (Barthlott et al 2017). These diverse surfaces have led to highly adapted functional structures (Koch & Barthlott 2009). The spread area of herbicidal droplets of Chenopodium album was analyzed by Sanyal et al (2006), whereas the effect of emitted dust particles on the distribution of Atriplex leucoclada was investigated by Oran & Al Zoubi (2016)
