Physiological mechanism underlying spikelet degeneration in rice [PDF]
Journal of Integrative Agriculture, 2018 The phenomenon of degenerated spikelets is very common in cereals, and considered as a serious physiological defect and a main constraint to grain production.

Effects of Non-Structural Carbohydrates on Spikelet Differentiation in Rice [PDF]
Plant Production Science, 2001 Spikelet number per unit area is a strong determinant of rice yield, and spikelet differentiation must be promoted to increase spikelet number. Nitrogen has been considered to be the most critical factor in promoting spikelet differentiation and the role

Response of Spikelet Number per Panicle in Rice Cultivars to Three Transplanting Densities [PDF]
Plant Production Science, 2010 Spikelet number per panicle (SPP), differentiated spikelet number per panicle (D-SPP), and preflowering aborted spikelet number per panicle (A-SPP) were examined in five rice cultivars at three planting densities (HD; high, MD; medium, LD; low planting ...

Transcriptome analysis reveals the role of jasmonate in regulating maize spikelet opening and seed set under high temperature stress [PDF]
Frontiers in Plant ScienceIntroductionMaize is a crucial cereal crop, yet it is highly susceptible to heat stress, which considerably limits its grain yield. The opening of spikelets is a critical prerequisite for pollen shedding.

Initiation and Development of Spikelets and Florets in Wheat as Influenced by Shading and Nitrogen Supply at the Spikelet Phase [PDF]
Plant Production Science, 2001 The spike of the main culm in winter wheat was examined by scanning electron microscopy from the double ridge to 6 days after the terminal spikelet stage to quantitatively evaluate the effects of shading and nitrogen supply at the spikelet phase on the ...

MULTI-FLORET SPIKELET 4 (MFS4) Regulates Spikelet Development and Grain Size in Rice
Rice Science, 2021 In rice, the spikelet is the basic unit of inflorescence, and its development is important for determining the grain yield and quality. We reported a rice spikelet mutant multi-floret spikelet 4 (mfs4) which resulted in the production of extra floral ...

Optimized nitrogen application increases rice yield by improving the quality of tillers
Plant Production Science, 2022 The quantity and quality of tillers determine the yield of rice. In order to explore how optimized nitrogen fertilizer application (OFA) increases rice yield by affecting tiller growth, a pot experiment with three nitrogen treatments was performed on the

The Streptochaeta Genome and the Evolution of the Grasses
Frontiers in Plant Science, 2021 In this work, we sequenced and annotated the genome of Streptochaeta angustifolia, one of two genera in the grass subfamily Anomochlooideae, a lineage sister to all other grasses. The final assembly size is over 99% of the estimated genome size.

Journal of Experimental Botany, 2021 Abstract The potential to increase barley grain yield lies in the indeterminate nature of its inflorescence meristem, which produces spikelets, the basic reproductive unit in grasses that are linked to reproductive success. During early reproductive growth, barley spikes pass through the maximum yield potential—a stage after which no new
