02) based on Pn at early filling stage, the flowering period, plant height, spikelet number, sterile spikelets, 1000 grain weight, harvest index and grain yield per plot (Table 5).
After several branches are produced, the IM switches and generates axillary meristems that produce one spikelet (spikelet meristem, SM), which is a determinate meristem.
The spikelet sterility showed a tendency of negative correlation with grain yield among the most productive genotypes, G1 and G2, when they were subjected to water stress (Table 4).
The anthers from each spikelet were smeared in a drop of 1% I2-KI solution on a glass slide separately and observed under compound microscope.
Despite higher spikelet production, straw mulching did not improve the grain filling in aerobic rice.
We developed the productive sorghum line by inducing a mutation of sorghum plants that allowed infertile spikelets to grow and produce seed," says Xin.
It was observed that the biomass and filled spikelet is not effected for 5 days of irrigation difference, exceding that time, it would reduce the biomass and filled spikelet percentage and also reduce yield.
The reduction in spikelet production under reduced water supply might be due to the abortion of spikelets in the secondary rachis branch, as documented by Kato et al.
9-1 mm wide, 3-5-veined, densely pilose in the spaces between the veins, veins glabrous, the hairs clavate, brown, with bulbous apices that are truncate or slightly rounded; sterile lemma slightly shorter than the spikelet, leaving free the apex of the fertile floret, 5-veined, the veins unequally spaced, sometimes the outer ones reduced, densely pilose in the spaces between the veins, the hairs clavate, brown, with bulbous apices that are truncate or slightly rounded; sterile palea minute; lodicules fused; fertile lemma, 2.
We excluded from the analysis both the first pair of spikelets (due to its variability) and the terminal sessile spikelet (because of the truncation) of each floriferous branch (Nagahama, 2012).
