“…In general water deficit treatment significantly reduced hulling %, milling %, head rice %, amylose content %, gelatinization temperature and grain shape. These results confirm that reported by Rayee et al, (2021). The interaction between genotypes, environments (normal and water deficit conditions) and seasons are shown in Table 7.…”

Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station during 2019 and 2020 growing seasons, to evaluate 21 rice genotypes (18 new promising lines and three commercial check varieties) for grain yield, yield components and quality characters under normal and water deficit conditions. Moreover, eight stress tolerance indices were calculated based on grain yield under water deficit and normal conditions to differentiate the water deficit tolerant genotypes from sensitive ones. The results showed that the variances due to years, environments, genotypes and their interactions were significant for most studied traits. All mean values of the studied traits decreased under water deficit stress condition compared to those under normal condition. The earliest genotypes were L4, L15 and L12 under normal condition. Whereas under stress condition L11,Giza 179 and Sakha 107 were the earliest ones. The most desirable mean values towards dwarfness were recorded by the lines L1 and L9. While, L13 and L2 had the highest mean values towards tallness. Moreover, Line 2 recorded the most desirable estimates for grain quality characters across all environments. The lines L14, L12 and L3 gave the highest grain yield and stress tolerance index (STI), while L6 displayed the lowest grain yield and STI. Moreover, the results indicated that harmonic mean (HM) and yield index (YI) indices gave similar ranks for these lines which considered as water deficit tolerant genotypes. Accordingly, these lines could be used in breeding programs to transmit tolerance genes to commercial cultivars for reduced irrigation.

“…Ample evidence found that the qualitative characters of white rice were closely related to gel consistency, chalkiness rice rate, contents of protein, total starch, and amylose contents [4]. Subsequent results discovered that compare to the control group (83.1 ± 2.4 mm), HNW could increase the gel consistency to 91.4 ± 3.4 mm (Figure 5A), a relatively perfect support for higher quality of eaten rice [34]. Strikingly, the chalkiness rate of rice was obviously decreased by HNW (Figure 5B).…”

How to use environmentally friendly technology to enhance rice field and grain quality is a challenge for the scientific community. Here, we showed that the application of molecular hydrogen in the form of hydrogen nanobubble water could increase the length, width, and thickness of brown/rough rice and white rice, as well as 1000-grain weight, compared to the irrigation with ditch water. The above results were well matched with the transcriptional profiles of representative genes related to high yield, including up-regulation of heterotrimeric G protein β-subunit gene (RGB1) for cellular proliferation, Grain size 5 (GS5) for grain width, Small grain 1 (SMG1) for grain length and width, Grain weight 8 (GW8) for grain width and weight, and down-regulation of negatively correlated gene Grain size 3 (GS3) for grain length. Meanwhile, although total starch content in white rice is not altered by HNW, the content of amylose was decreased by 31.6%, which was parallel to the changes in the transcripts of the amylose metabolism genes. In particular, cadmium accumulation in white rice was significantly reduced, reaching 52% of the control group. This phenomenon was correlated well with the differential expression of transporter genes responsible for Cd entering plants, including down-regulated Natural resistance-associated macrophage protein (Nramp5), Heavy metal transporting ATPase (HMA2 and HMA3), and Iron-regulated transporters (IRT1), and for decreasing Cd accumulation in grain, including down-regulated Low cadmium (LCD). This study clearly showed that the application of molecular hydrogen might be used as an effective approach to increase field and grain quality of rice.

“…The final grain yield at 14% of the moisture was then calculated based on the weight and the determined moisture. The gel consistency of the rice grains was determined according to the method illustrated by Rayee et al (2021). The grain protein content was calculated by multiplying grain N content with 5.95 (Yasui and Tsutsumi, 1982).…”

This study aimed to evaluate the effects of sowing density and iron (Fe) coated seeds on rice grain yield, grain quality, and soil properties in saline soils in Phuoc Long district, Bac Lieu province, Vietnam. Experimental treatments include: (T1) Intact dry seed (50 kg seed/ha); (T2) Hydro-primed seed (120 kg seed/ha); (T3) Hydro-primed seed (50 kg seed/ha); (T4) Hydro-primed then sprouted seed (50 kg seed/ha); (T5) Fe-coated dry seed (50 kg seed/ha); (T6) Fe-coated hydro-primed seed (120 kg seed/ha); (T7) Fe-coated hydro-primed seed (50 kg seed/ha); (T8) Fe-coated hydro-primed seed which was sprouted before sowing (50 kg seed/ha); (T9) Hydro-primed then sprouted seed (120 kg seed/ha); (T10) Transplanting (50 kg seed/ha). The results indicated that applying Fe-coated seeds significantly increased tiller number at 45 and 60 DAS compared to free-Fe-coated seeds and transplanting treatments. There was no significant difference in tiller number among treatments at harvest stage. The plant height, yield, amylose, protein contents, gel consistency, soil pH, Eh, and Fe content in soil solution among the treatments did not differ significantly. This study demonstrated that reducing seed rate, broadcasting dry seeds, and coating seeds with Fe could reduce production cost while plant growth, yield and grain quality are maintained.
