Raceme rachis and pedicels pubescent or puberulent ; bract and bracteole usually borne on distal 1/2 of pedicel.
The activity of catalase in rachis branches of ratooning rice of HMST and LST varieties improved with declining stubble height, whereas a contrary trend was observed for HST ones.
It showed that the vascular bundle system of rachis in wheat changed apparently under water deficit.
Leaves bipinnate,10-25 cm long, usually with2 pairs of pinnae, rachis often ending in a tendril; pinnae with2-4 pairs of leaflets and terminal tendrils; leaflets opposite, oblong or long obovate,3-9 cm long,1.5-4 cm wide, apex obtuse or emarginated, base slightly oblique.
Moreover, it mainly resulted in shortened internode under the rachis internode, with forming good plant shape, and increasing the number of ear bearing tiller, but decreasing the per ear grain number.
Its anthotaxy is spica, and amphimixis flowers is serried inserted on the thick rachis.
Pedicels of spikelet pair equal, as long as rachis internode; upper glume with 0. 5-1 mm mucro.
