This study tested the hypothesis that interaction between polyamines and ethylene may mediate effects of soil drying on grain filling rice (Oryza sativa L.). Two cultivars were pot grown. Three treatments, well-watered, moderate (MD), severe (SD), imposed from 8 d post-anthesis until maturity. The endosperm cell division rate, grain-filling weight earlier flowering superior spikelets showed no significant differences among three treatments. However, those later inferior significantly...
Applying organic fertilizer coupled with chemical has been widely adopted to improve crop productivity and quality develop sustainable agriculture. However, little information is available about the effects of on grain rice (Oryza sativa L.), especially nutritional starch quality. In present study, high yielding 'super' cultivars were grown in field three cultivation practices, including zero nitrogen application (0N), local practice (T1) T1 treatment additional (T2).Application...
Summary In wheat stems, the levels of fructan‐dominated water‐soluble carbohydrates ( WSC ) do not always correlate well with grain yield. Field drought experiments were carried out to further explain this lack correlation. Wheat Triticum aestivum varieties, Westonia, Kauz and c . 20 genetically diverse double haploid DH lines derived from them investigated. Substantial genotypic differences in fructan remobilization found 1‐ FEH w3 gene was shown be major contributor stem process based on...
The use of nitrogen (N)-efficient rice (Oryza sativa L.) varieties could reduce excessive N input without sacrificing yields. However, the plant traits associated with N-efficient have not been fully defined or comprehensively explored. Here, three japonica (NEVs) and N-inefficient (NIVs) were grown in a paddy field under omission (0 N, 0 kg ha–1) normal (NN, 180 200 ha−1) treatments. Results showed that NEVs exhibited higher grain yield efficiency (NUE) than NIVs both treatments, due to...
Brassinosteroids (BRs) are a new group of plant hormones and play important roles in growth development. However, little information is available if BRs could regulate spikelet development rice (Oryza sativa L.) especially under soil-drying conditions. This study investigated whether how mediate the effect on differentiation degeneration rice. A cultivar was field-grown exposed to three soil moisture treatments during panicle development, that is, well-watered (WW), moderate (MD) severe...
Alternate wetting and moderate soil drying irrigation (WMD) has been widely adopted in rice ( Oryza sativa L.) production for saving water increasing grain yield. However, limited information is available about the effect of WMD on quality. The main purpose this study was to evaluate characteristics quality response WMD. Two varieties, Yangdao 6 (YD6, indica ) Hanyou 8 (HY8, japonica ), were grown field, with two management treatments, well‐watered (WW) from 10 d after transplanting...
Abstract Hybrid rice ( Oryza sativa L.) varieties usually need more N application to produce a higher grain yield and exhibit lower use efficiency (NUE) than inbreds. However, little information is available about the mechanism underlying an indica – japonica variety with high NUE under low rates. This study investigated this issue. The hybrid Yongyou 2640 (Y‐2640) inbred Lianjing 7 (L‐7) were grown in paddy field at rates of 0 200 kg ha −1 . results showed that internal (grain yield/total...
Abstract This study tested the hypothesis that brassinosteroids (BRs) mediate moderate soil‐drying (MD) to alleviate spikelet degeneration under high temperature (HT) stress during meiosis of rice ( Oryza sativa L.). A cultivar was pot‐grown and subjected normal (NT) HT treatments meiosis, two irrigation regimes including well‐watered (WW) MD were imposed plants simultaneously. The effectively alleviated yield loss mainly via improving root activity canopy panicle traits higher...
Abstract High temperatures (HT) and drought are two major factors restricting wheat growth in the early stages. This study investigated role of glutathione (GSH) amendment (0.0, 0.5, 1.0, 2.0 mM) to soil mitigating adverse effect HT (33 °C, with 25 °C as a control), water regimes (60% field capacity their combinations. decreased length, project area, surface volume, forks root, while had reverse effect. Shoot leaf relative content, shoot root dry matter were significantly by drought,...
摘要:
Aligning leaf nitrogen (N) distribution to match the light gradient is crucial for maximizing canopy dry matter production (DMP) and improving N utilization efficiency. However, relationship between of root-derived cytokinins in rice leaves, along with its impact on DMP underlying mechanisms, remains poorly understood. A two-year field experiment was conducted using two japonica N-efficient varieties (NEVs) N-inefficient (NIVs) under four different rates (0, 90, 180 360 kg ha−1). These...
Abstract The plant steroid hormones brassinosteroids (BRs) play pivotal roles in modulating flower and fruit production. Nitrogen (N) is a key factor affecting rice ( Oryza sativa L.) We hypothesized that BRs would respond to N application rates at spikelet differentiation (SD) regulate degeneration rice. Three cultivars were field‐grown treated with five SD. Plant contents, antioxidant capacity, energy status observed during meiosis young panicles, their relationships evaluated. In all the...
This study investigated whether and how brassinosteroids (BRs) mediate the effect of soil-drying during meiosis on spikelet degeneration in rice (Oryza sativa L.). A field-grown cultivar was exposed to three soil moisture treatments meiosis: well-watered (WW), moderate (MD) severe (SD). Compared with WW treatment, MD treatment enhanced BRs biosynthesis, reduced degeneration, increased grain yield. The SD had opposite effects. Changes levels adenosine triphosphate (ATP), energy charge,...
