Morphometric variations in caryopses and seedlings of two grass species growing under contrasting habitats.

摘要: Urochondra setulosa grows in marine conditions, while Sporobolus indicus near fresh water and sometimes also close to moist places along roadside areas. Both species belong the same tribe family. The two grass growing under different habitats showed characteristic variations their morphometric traits of caryopsis seedlings. U. salty area had features, e.g. leaf culm with salt deposition, rigid blade pointed tip, S. glabrous nodes internodes. Morphometric analysis caryopses both very similar without prominent differences length, breadth thickness. But light microscopy scanning electron microscopic (SEM) studies variations. Under microscopy, features like colour, shape compression among species. SEM revealed a reticulate type pattern sculpturing on dorsal ventral surfaces, whereas anticlinal periclinal walls were elevated folded walls, non undulating walls. In conclusion, each individual ecotype evolves some morphological thrive well particular environment. studied hereby, grown habitats, remarkable differentiations characters, thus indicating that play major role plant growth.
