ABSTRACT Close mixed-planting is a new concept of mixed cropping that allows greater complementary effects under various stress conditions; in this system, oxygen and/or water transfer occurs through the tightly entangled root system of the two species. We aimed to assess whether rice can alleviate flood stress in soybeans via close mixed-planting. A three-year field experiment and one water culture experiment were conducted to compare the crop performance between single and close mixed-planting under short-term flood (or anoxia) stresses. The survival rates, photosynthetic rates, and biomass production were higher in the mixed soybean than in the single soybean plants. Moreover, as the modified land equivalent ratio under flood stress was always >1, rice exhibited greater complementary effect on soybean against short-term flood stress in an upland field converted from paddy. Thus, rice planted as the partner crop of soybean can alleviate short-term anaerobic stress to enhance soybean growth. Graphical Abstract

ABSTRACT Growth promotion through application of ultrafine bubbles (UFBs) was observed in several crop species grown under suboptimal conditions. In the current study, mitigation of osmotic stress through polyethylene glycol 6000 (PEG6000) was analyzed in soybean seedlings to assess the effects of UFB on plants under soil drought stress. In no-nutrient conditions, growth suppression due to osmotic stress was increasingly mitigated by UFB application as stress intensity increased. Shoot biomass of UFB-treated plants (at all examined PEG6000 concentrations) exceeded to that of the absolute control. Production of superoxide radicals (O2 −) under osmotic stress was 1.5-fold higher than that in the control, whereas that in UFB-treated plant showed a similar level as the absolute control. The reduction of O2 − through treatment with UFB may help mitigate osmotic stress. In conclusion, this study quantitatively showed that UFB was effective in reducing osmotic stress in soybean seedlings.

ABSTRACT C4 plants have higher photosynthetic nitrogen- and water-use efficiencies (PNUE and PWUE) than C3 plants. Some studies on C4 grasses have reported that NADP-malic enzyme (NADP-ME) grasses have higher PNUE than NAD-malic enzyme (NAD-ME) grasses, whereas other studies have suggested that this difference is caused by the traits of phylogenetic lineage. Further extensive studies are required to properly understand the PNUE and PWUE of C4 grasses. We investigated the PNUE and PWUE for 22 grass species of four photosynthetic types [4 NADP-ME, 6 NAD-ME, 6 phosphoenolpyruvate carboxykinase (PCK), and 6 C3 species] grown under two N supply levels. Under the same N level, the three C4 types showed higher photosynthetic rate and lower stomatal conductance and transpiration rate than the C3 type, but these parameters were similar in the C4 types. Although there were no significant differences in leaf mass per area and N content per leaf area among the four types, these traits tended to be somewhat lower in the NADP-ME type than in other types. As a result, PNUE was highest in the NADP-ME type, lowest in the C3 type, and intermediate in the NAD-ME and PCK types. PWUE was much higher in the C4 types than in the C3 type but similar in the C4 types. The N supply level did not greatly affect the trends of PNUE and PWUE. This study suggests that the NAD-ME and PCK grasses have the N-related physiological traits similar to each other but differing from the NADP-ME grasses. GRAPHICAL ABSTRACT

ABSTRACT Different varieties of foxtail millet (Setaria italica (L.) P. Beauv) are grown in Japan; there are several varieties of Mukodamashi, and they are cultivated in more than 10 prefectures. However, while most of Mukodamashi varieties have white grains and waxy endosperms, it is uncertain whether they have the same or different genotypes. In this study, five Mukodamashi varieties, from Gunma, Miyazaki, Ehime, Kochi, and Nara Prefectures, as well as 23 other local varieties of foxtail millet, were examined using simple sequence repeat markers to elucidate their genetic identities. The five Mukodamashi varieties have different genotypes. Therefore, we concluded that different varieties in different areas have been named Mukodamashi. It is possible that local varieties with the same name are actually different varieties, even if they have similar characters. Graphical Abstract

ABSTRACT With increasing annual global coffee consumption, the amount of spent coffee grounds (SCGs) increases. Direct application of SCGs in large agricultural fields can potentially improve soil and control weeds in an environmentally safe manner. However, except for composting, the use of SCGs during cropping has not been implemented thus far because of inhibitory effects on crop growth observed in pot-based studies. We evaluated the effect of a top dressing approach to direct SCG application on crop biomass, soil improvement, and weed control, through double cropping field experiments using wheat and soybean. The field experiments were conducted over six successive cropping seasons in an upland field converted from paddy, and crop and weed biomass as well as soil total carbon and nitrogen were investigated. To avoid growth inhibition, the SCGs were surface broadcasted after crop germination to mimic living mulch. The soil total carbon and nitrogen contents increased significantly under an SCG concentration of 5 kg m−2 or more, approximately 20 months after the first application, whereas SCG application did not significantly affect crop yield except for the first cropping of wheat. In addition, the 10 kg m−2 SCG application reduced the weed biomass by 50% or more during cropping, except for the wheat cropping in the second year. We concluded that top dressing with SCGs after crop germination is an efficient method for sustainable agricultural production, although further detailed studies of SCGs’ effect on the crop growth and soil characteristics are required.

摘要随着全球咖啡年消费量的增加，废咖啡渣的数量也在增加。SCG在大型农田中的直接应用有可能以环境安全的方式改善土壤和控制杂草。然而，除了堆肥之外，由于在基于盆栽的研究中观察到的对作物生长的抑制作用，迄今为止尚未在种植期间使用SCG。我们通过小麦和大豆的双季田间试验，评估了直接施用SCG的追肥方法对作物生物量、土壤改良和杂草控制的影响。在一块由稻田转为旱地的连续六个种植季节进行了田间试验，研究了作物和杂草的生物量以及土壤总碳和总氮。为了避免生长抑制，SCG在作物发芽后进行表面广播，以模拟活的覆盖物。在第一次施用SCG浓度为5 kg m−2或更高的情况下，土壤总碳和氮含量显著增加，大约在第一次种植小麦后20个月，而施用SCG对作物产量没有显著影响。此外，除第二年种植小麦外，施用10 kg m−2 SCG可使杂草生物量在种植期间减少50%或更多。我们得出的结论是，作物发芽后用SCG追肥是可持续农业生产的有效方法，尽管还需要进一步详细研究SCG对作物生长和土壤特性的影响。图形摘要

ABSTRACT Understanding the yield potential and yield-determining factors of recent high-yielding cultivars is essential for further increasing rice yield. In this study, a cross-locational field experiment was conducted across 3 years using ‘Hokuriku 193ʹ (H193), a high-yielding cultivar, at four sites including one in Nagano Prefecture, which is the highest-yielding region in Japan. The highest mean yields of 3 years, 1214 g m−2 for brown rice grains and 1586 g m−2 for rough grains, were recorded at the Nagano site. The yields from the 17 environments were strongly correlated with spikelet number per square meter while percentage of filled grain was relatively stable, suggesting that sink capacity is the primary determining factor for grain yield of H193. The climatic factors for high spikelet number at the Nagano site can be explained by the high cumulative radiation before heading associated with longer duration until heading by low night temperature. In addition, a large increase in shoot dry weight during grain filling (ΔW) and high radiation use efficiency (ΔW/rad) at the Nagano site could satisfy large source demand by the large sink size. The high ΔW/rad at the Nagano site associated with low night temperature. This study demonstrated high yield potential of H193 and revealed an environment that achieves extra-high yields in H193, which provided insight to attain further increase in rice yield.

摘要了解近期高产品种的产量潜力和产量决定因素对进一步提高水稻产量至关重要。在这项研究中，使用高产品种“Hokuriku 193”（H193）在四个地点进行了为期3年的跨地点田间试验，其中一个地点位于日本产量最高的长野县。长野地区记录了3年来的最高平均产量，糙米产量为1214 g m−2，粗粮产量为1586 g m−2。17个环境的产量与每平方米小穗数呈强相关，而灌浆粒率相对稳定，表明库容量是H193籽粒产量的主要决定因素。长野地区小穗数高的气候因素可以解释为抽穗前的高累积辐射与夜间低温下抽穗前的较长持续时间有关。此外，长野地区灌浆期间茎干重（ΔW）的大幅增加和高辐射利用效率（ΔW/rad）可以通过大水槽尺寸来满足大源需求。长野现场的高ΔW/rad与夜间低温有关。这项研究证明了H193的高产潜力，并揭示了H193实现超高产的环境，为进一步提高水稻产量提供了见解。图形摘要

ABSTRACT Breeding of common beans (Phaseolus vulgaris L.) shows restrictions in the genetic advance because of the effect of the environment. Therefore, the behavior of the yield components of genotypes varies according to the crop’s environment. The genotype x environment interaction can cause genotypes with high yields in one location not to behave in the same way in other localities, which limits the recommendation of cultivars for different environments. The objective of this research was to evaluate agronomic traits in new improved bean cultivars in high tropic environments, as well as to determine which cultivars show phenotypic stability for yield. Multi-environment tests were carried out during 2016 and 2017 in two regions of the department of Cundinamarca, in Colombia. Significant differences were found for the genotype x environment interaction and highly significant differences for the evaluation environments and genotypes. The greatest variation was attributed to genetic effects, followed by environmental effects and the genotype x environment interaction. The first two principal components for grain yield showed 88.86% of the variation of the genotype x environment interaction. Cultivars Serrania and Sutagao, of climbing growth habit, were identified as stable and with high yield potential, so they can be considered as a commercial alternative for bean growers.

ABSTRACT To understand the effect of heat stress on morphology and physiology of the cotton, eight cotton genotypes with their 15F1 hybrids (five lines, three testers) were grown in the field conditions under randomized complete block design (RCBD) with two treatments i.e. normal and high-temperature stresses with two replications followed by split-plot arrangement. Data were collected for biochemical and yield-related parameters. Mean values of all studied traits were reduced significantly under high-temperature stress whilst the mean value of lint%, catalase activity, total soluble proteins, peroxidase, and carotenoids were increased under high-temperature. Under both conditions, the number of bolls, boll weight, seed cotton yield, lint index, seed mass per boll, hydrogen peroxide content, catalase activity, total soluble proteins, carotenoids, and chlorophyll contents had high heritability values along with high genetic advance percent mean which revealed, these traits were controlled by additive gene action. The lint%, seed index, short fiber index, fiber strength, fiber fineness, upper half mean length and peroxidase activity had high heritability with moderate genetic advance under heat stress conditions which showed, these traits were controlled by non-additive gene action. Under both temperature conditions, FH-458, IUB-65, CRS-2, and FH-313 were good general combiners for physicochemical and yield-related traits. The cross combination of IUB-013× CRS-2 and FH-458× FH-313 were good specific combiner for plant height and seed cotton yield whilst for fiber quality and biochemical traits, the best specific combiners were VH-329× FH-313 and IUB-013× CRS-2. These identified parents and cross combinations might be used for improving already present commercial varieties under high-temperature stress.

The cross combination of IUB-013× CRS-2 and FH-458× FH-313 were good specific combiner for plant height and seed cotton yield whilst for fiber quality and biochemical traits, the best specific combiners were VH-329× FH-313 and IUB-013× CRS-2. These identified parents and cross combinations might be used for improving already present commercial varieties under high-temperature stress.","PeriodicalId":20259,"journal":{"name":"Plant Production Science","volume":"25 1","pages":"105 - 119"},"PeriodicalIF":2.5,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43456817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Water deficiency is the main bottleneck in potato production in many regions worldwide. The generation of higher tuber yields per unit of water is a key goal for both agronomists and potato growers. In this study, we found that under moderate deficit irrigation (DI; 50% relative water content (RWC)) at the seedling stage of potato growth, the leaf area index (LAI) and dry matter accumulation were lower than control; however, they caught up with and surpassed the control at later developmental stages with a normal water supply, and a higher yield was ultimately achieved. The LAI and total dry weight under severe water stress (35% RWC) also surpassed the control at harvest; however, the final yield remained low, due to the low distribution of dry matter into the tubers. Abscisic acid (ABA) increased under DI conditions at the seedling stage, while gibberellin (GA1 and GA3) levels decreased. Moreover, endogenous ABA increased as plant development proceeded from seedling stage to tuber initiation stage, regardless of water stress. Exogenous ABA application promoted dry matter accumulation and distribution into the tubers. Therefore, it may be that ABA, as a major signaling molecule, mediates water stress to regulate tuber sink capacity at early development period. Through a feedback regulation stronger source capacity was stimulated by sink enhancement mediated by moderate water stress at the seedling stage, reached a higher tuber yield finally by reestablishment of sink-source relationship.

ABSTRACT Previous research into the effects of ultrafine bubbles (UFB) on plant growth have been contradictory. To facilitate the resolution of these contradictions, the aim of the present study was to clarify the interspecific differences in growth responses among cereal/leguminous species under different levels of UFB concentrations. Seedlings of six species were grown hydroponically with three different UFB concentrations and two levels of plant nutrition to evaluate biomass and elongation growth. UFB growth promotion under zero-nutrition occurred in all species. Interspecific differences were noted in response to differing UFB concentration levels. Rice and soybean had higher above-ground biomass production at both low and high concentrations. Conversely, other crops exhibited promoted growth at only one of the concentrations. Negative effects occurred in full nutrient conditions except for root elongation. This study demonstrated that growth-promoting effects with UFB depended on the crop species being tested and the concentration of UFB used. Graphical abstract
