Carpel size, grain filling, and morphology determine individual grain weight in wheat [PDF]

Journal of Experimental Botany, 2015
Individual grain weight is a major yield component in wheat. To provide a comprehensive understanding of grain weight determination, the carpel size at anthesis, grain dry matter accumulation, grain water uptake and loss, grain morphological expansion ...

Extensin-like Protein OsPEX1 Modulates Grain Filling in Rice [PDF]

Plants
Grain filling is a vital factor influencing both rice grain yield and quality, yet its underlying mechanisms remain poorly understood. In this study, we perform a functional analysis of the grain-filling defective mutant pex1 in rice. pex1 plants produce

Extended grain filling has potential to improve yield in grain sorghum. [PDF]

J Exp Bot
Abstract Yield increase in sorghum has been achieved primarily by increasing grain number. Scope exists to increase yield by increasing grain size; however, this has been limited by the negative correlation between grain size and grain number. Extending the duration of the grain-filling period has potential to enable increased grain size

Grain-Filling Rate Improves Physical Grain Quality in Barley Under Heat Stress Conditions During the Grain-Filling Period

Frontiers in Plant Science, 2022
Heat stress is a primary constraint to Australia's barley production. In addition to impacting grain yield, it adversely affects physical grain quality (weight and plumpness) and market value.

Maize grain filling characteristics in China: Response to meteorological factors [PDF]

Heliyon
To investigate the dynamic changes in dry matter accumulation in maize after anthesis, we established a logistic model to describe grain filling characteristics (GFC), and analyzed differences between spring and summer maize, and the influence of ...

Regulation of Rice Grain Quality by Exogenous Kinetin During Grain-Filling Period. [PDF]

Plants (Basel)
Cytokinins (CKs) play important functions in plant growth and development and in response to adversity stress. However, little is known about the role CK plays in rice grain quality. We hypothesized that exogenous cytokinins could improve rice grain quality by regulating physiological traits and genes related to starch synthesis.

The Effects of Photoperiodic Transcription Factor OsPRR37 on Grain Filling and Starch Synthesis During Rice Caryopsis Development [PDF]

Plants
Grain filling governs grain weight formation in rice, while starch biosynthesis during this process critically determines both grain quality and yield.

Assessing effects of temperature driven by sowing dates on the grain filling and kernel weight of corn in the North China Plain [PDF]

Frontiers in Plant Science
IntroductionThe grain filling process is strongly influenced by weather during the reproductive growth stage, but grain filling and yield of corn under various weather conditions resulting from different sowing dates remain uncertain.MethodsA two-year ...

Combining Controlled-Release and Normal Urea Enhances Rice Grain Quality and Starch Properties by Improving Carbohydrate Supply and Grain Filling [PDF]

Plants
Controlled-release nitrogen fertilizers are gaining popularity in rice (Oryza stavia L.) cultivation for their ability to increase yields while reducing environmental impact. Grain filling is essential for both the yield and quality of rice. However, the

Comparative Proteomic Analysis Provides New Insights into Improved Grain-filling in Ratoon Season Rice [PDF]

Rice
Grain-filling of rice spikelets (particularly for the later flowering inferior spikelets) is an important characteristic that affects both quality and yield.
