Distribution of dry matter in reproductive culms of grasses is related to plant morphology and can be described based on phytomers, Our objective was to describe the morphology of the phytomers of reproductive culms of big bluestem (Andropogon gerard

Soybean [ Glycine max (L.) Merr.] breeders can sometimes increase genetic variability in their germplasm through wide crosses with plant introduction (PI) material, and in that way lead to slow progress in developing high-yielding cultivars. A study

Both C 3 and C 4 grasses exhibit similar morphological responses to shade, but they differ in photosynthesis-related responses to shade, such as forage yield and growth rate. Morphological adaptation and reduced photosynthesis under shade may affect

Several studies have compared C 3 and C 4 species for response to water and temperature regimes. Little comparative information exists, however, on growth responses of C 3 and C 4 species to irradiance regime. The objective of this study was to deter

Breeding schemes to improve alfalfa (Medicago sativa L.) forage quality based on total herbage chemical composition can result in altered morphology. Additionally, cell-wall composition of plant parts also may be altered. This study investigated the
