Summary: The research proposed an image-based strategy and methodology to evaluate oat panicles, obtaining panicle traits through image analysis using MATLAB. The heritability of all panicle traits was high between 0.76 and 0.93, and significant genotypic differences for panicle architecture traits could be detected with a high power of 0.80 using six panicles per replication.

Summary: This study investigated the effects of sink capacity, nitrogen, and dry matter accumulation on rice grain yield through a field experiment. The results showed that a high sink capacity can increase rice yield by increasing nitrogen and dry matter accumulation. Therefore, the T2M1 treatment is a promising approach for improving rice grain yield.

Summary: The frequency of heavy rains is increasing in regions with high annual rainfall due to climate change, affecting crop growth and yields. Moderate defoliation can increase soybean yield, while heavy defoliation decreases growth and yield. A 15% defoliation rate reduces leaf redundancy, improves light transmittance, promotes dry matter translocation to reproductive parts, and ultimately enhances seed yield.

Summary: This study investigated the impact of oat catch crops on mineral nitrogen leaching losses from cool season fodder beet grazing. The results showed that sowing oats can significantly reduce these losses, with the timing of urine application and soil type playing a major role.

Summary: Recent research suggests that modifying leaf-colour traits can improve canopy photosynthesis by allowing light penetration. However, the effects of leaf-colour modification on other growth-related traits and the mechanisms behind the increased photosynthesis remain unclear. This study found that yellow-leaf variants had a greater impact on crop growth and development compared to stay-green variants, but the delayed senescence in yellow-leaf variants contributed to improved photosynthesis.

Summary: This study investigated the effects of nitrogen fertilizer on rice yield, nutrient utilization efficiency, and physiological mechanisms. The results showed that the optimal total nitrogen application rates were 305.5 kg/ha, 307.6 kg/ha, and 298.0 kg/ha for the three varieties, with corresponding yields of 10.3 t/ha, 10.6 t/ha, and 10.2 t/ha, respectively. Leaf photosynthetic rate, non-structural carbohydrate accumulation in stems, root oxidation activity, Z+ZR contents in roots, and NR and GOGAT activity in leaves were positively correlated with yield and nitrogen accumulation. The highest yield of 9.72 t/ha was obtained with a panicle nitrogen application rate of 108 kg/ha.

Summary: Breeding elephant grass for bioenergy purposes involves selecting genotypes with high total dry biomass and adaptability/stability through repeated harvests. Research shows that a minimum of seven harvests is needed for accurate selection of clones, with accuracies of 59% and 72% achieved through two and four harvests, respectively.

Summary: This study evaluated the effect of different doses and application times of the growth regulator trinexapac-ethyl on the industrial quality of white oat grains. The results showed that within a certain range of doses, the application of trinexapac-ethyl does not affect the industrial quality of grains, but at high doses, it reduces the industrial quality of grains.

Summary: A mathematical model is proposed in this study to estimate the dry mass yield of indoor-grown lettuce under different light spectra, taking into consideration the effects of spectral distribution and photon flux density on plant photosynthetic rate and morphology. Experimental data is used to fit models for the modified quantum use efficiency coefficient, and the accuracy of these models is compared. Normalizing the overall spectral distribution leads to a more accurate prediction of the investigated parameter.
