“…When starch is heated in water, starch granules will gradually expand, and amylose will continue to be leached, and amylopectin will solubilize, resulting in the production of a paste. To a certain extent, the starch pasting behavior determines rice cooking quality and functionality, since starch is the main component of rice ( 34 ). Rice starch with low amylose exhibited relatively higher swelling power than high-amylose starch, so low amylose content promotes starch gelatinization ( 35 ).…”

Taste quality of rice is the key to its value. However, it is greatly affected by rice types and the environment. It is a complex but necessary factor to accurately evaluate the taste quality of various types of rice in different environments. In this study, 7 different types of rice with different taste values were used as materials, and 12 nitrogen fertilizer treatments were applied to obtain 84 different rice taste values. We used protein content, amylose content, and RVA to evaluate changes in the taste value of rice. Rice with high taste value tended to have higher amylose content, peak viscosity, hold viscosity, final viscosity, and breakdown, as well as lower protein content, pasting temperature, and peak time. Protein and amylose contents affected the taste value of rice by affecting the RVA profiles except for setback. For high and low taste-value rice types, protein content could explain 66.8 and 42.9% of the variation in taste value, respectively. In the case of medium taste-value type, protein content was not enough to evaluate the taste quality of rice. Stickiness could explain 59.6% of the variation in taste value. When the protein content of rice was less than 6.61% or greater than 9.34%, it could be used to reflect the taste quality of rice. When the protein content was in between the two, protein content was not enough to reflect the taste quality of rice. Our results suggested that protein content could better reflect the taste quality change for rice, which provided a theoretical and technical basis for the accurate evaluation of the taste value of various types of rice.

“…At the same time, under the effect of strip deep loosening, the growth of the roots in the lower layer of the soil was promoted. Root bleeding sap is an indicator of root pressure, plant growth potential, and root activity [ 50 ]. Stronger root activity is conducive to the absorption of water and nutrients by the root system and promotes the growth of aboveground plants [ 51 ].…”

Inappropriate spatial distribution of canopy and roots limits further improvements to the grain yield of maize with increased planting density. We explored an integrated management practice called strip deep rotary with staggered planting (SRS) which includes comprehensive technology for both canopy layers and topsoil. Here, field experiments were conducted under two maize cropping systems (spring maize and summer maize) to evaluate the effect of SRS on the spatial distribution of the canopy and roots for maize under high planting density (90,000 plants ha−1) and to determine the physiological factors involved in yield formation. Compared with conventional management practices (no-tillage with single planting, NTS), SRS decreased the LAI of the middle to top layers while improving the light distribution of the middle and lower layers by 72.99% and 84.78%, respectively. Meanwhile, SRS increased the root dry weight density and root sap bleeding by 51.26% and 21.77%, respectively, due to the reduction in soil bulk density by an average of 5.08% in the 0–40 cm soil layer. SRS improved the SPAD in the ear and lower leaves and maximized the LAD, which was conducive to dry matter accumulation (DMA), increasing it by 14.02–24.16% compared to that of NTS. As a result, SRS increased maize grain yield by 6.71–25.44%. These results suggest that strip deep rotary combined with staggered planting noticeably optimized the distribution of light in the canopy and reduced the soil bulk density to promote root vitality and growth, to maintain canopy longevity, and to promote the accumulation of dry matter, which eventually increased the grain yield of the maize under high planting density conditions. Therefore, SRS can be considered a better choice for the sustainable high yield of maize under high-density planting conditions in the NCP and similar areas throughout the world.

“…It is reported that cooking and eating quality of rice can be improved by ratooning, and SBE, SS, and AGP drives the improvement in ratoon rice (Huang, Pan et al, 2020). Starch quality of rice was enhanced through the regulation of SBE, SS, and AGP in grains during the improvement of midseason indica rice in last 80 yr (Zhang et al, 2020). So far only Waxy gene has been found to affect amylose content (Wang et al, 1995) and ALK is related to gelatinization temperature (Gao et al, 2003).…”

In this study, field experiments were conducted in 2 yr with two rice varieties to compare use of light and temperature resources, crop growth characteristics, yield traits, and cooking and eating quality of machine-transplanted rice (Oryza sativa) in rice-wheat (Triticum aestivum) double cropping system among five sowing dates.The results showed that the total growth duration, total cumulative temperature, and total cumulative solar radiation and total biomass production from transplanting to maturity decreased with the delay in sowing date. The first sowing date (22 May) had a 1.8-11.7% higher total biomass production and 0.2-16.7% higher grain yield than the other four sowing dates (29 May, 5 June, 11 June, 18 June) across two cultivars and 2 yr. Early sowing increased leaf aera index at heading and maturity, daily mean temperature, cumulative temperature, use efficiency of cumulative temperature and solar radiation, crop growth rate, leaf area duration, and biomass production during jointing to heading and heading to maturity. Early sowing increased gel consistency, reduced amylose and protein content and increased the taste value of cooked rice. When the sowing date was delayed, rice starch Rapid Viscosity Analyzer (RVA) profile parameter, including the peak viscosity and breakdown value decreased, and the setback value increased. These results suggest that early sowing can improve use of temperature and light resources, crop growth characteristics, starch RVA spectrum characteristics, reduce rice protein content, and consequently increase biomass production, grain yield, and improve cooking and eating quality of machine-transplanted rice in eastern China. INTRODUCTIONRice (Oryza sativa) is the staple food for more than 65% of the population in China and nearly 4 billion people in Asia, where 90% of the rice produced and consumed globally
