Through subsequent experiments, the researchers found that jasmonic acid prevents pedicellate spikelets from producing seeds.
In this context, this work evaluated the effect of temperature at microsporogenesis on spikelet sterility of paddy rice, with the aim to identify genotypes tolerant to low temperatures at this growth stage.
Under rainfed condition, significantly phenotypic and genetic positive correlations existed between the Pn at the middle filling stage; Tr, Gs at the early and middle filling stages, spikelet number, grain number per spike and drought resistance index, and the environmental correlations were small, it showed that the correlation variations were mainly caused by genes.
In this model for Cyperaceae, any meristem may have one of these three fates: it may (1) produce indeterminate lateral branches, (2) terminate in a spikelet, or (3) stop the development without forming organs.
Additionally, Fukai, Pantuwan, Jongdee, and Cooper (1999) stated that the maintenance of a high water potential in the plant during pre-flowering is associated with a higher panicle water potential, reducing the delay in flowering and lowered spikelet sterility, which contribute to higher yield.
The test cross nursery was raised and observations were recorded on agronomical traits of interest and also on pollen and spikelet fertility.
Primary pedunculate rays many, dissimilar, all with cluster of 5-15 spikelets at their tips.
Rice straw mulching in aerobic rice improved spikelet production although it only increased the number of empty spikelets (Table 2) while neither varying fertilizer dosages nor SPAD-based fertilizer application had any significant effect on the yield components of aerobic rice (Table 3 and Table 4, respectively).
The researchers developed the higher yielding sorghum by taking advantage of a plant part called a "spikelet" A spikelet is a cluster of florets found in the panicle and is a characteristic of other grasses, such as millet or rye.
In the current study, it was observed that the biomass and filled spikelet was not effected for 5 days of irrigation difference, exceding this time, there would be reduction of the biomass and filled spikelet percentage and also reduce yield.
Cold temperatures during the cultivation of rice can result in chlorosis, incomplete and irregular panicle exertion, and spikelet sterility.
