ABSTRACT Because of inadequate freshwater resources and poor irrigation facilities, salinity drought often co‐occur for rice production in saline lands. The root is the primary most vulnerable organ detecting perceiving stresses soil. Still, little information available on morpho‐physiological characteristics grain yield when subjected to combined salinity‐drought stress. present study was conducted under two levels (NS, non‐salinity treatment; S, treatment) three imposed from jointing...
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,...
Understanding the morphological and physiological traits associated with improved filling efficiency in large-panicle rice varieties is critical to devise strategies for breeding programs cultivation management practices. Information on such traits, however, remains limited. Two high filled-grain percentage (HF) two check low (LF) were field-grown 2012 2013. The number of spikelets per panicle HF LF both exceeded 300, (%) was approximately 90, while that 75 over years. results showed when...
Dense planting could be a feasible method for reducing nitrogen (N) application rates without compromising rice grain yield in northeast and central China. It is still unclear whether reduced N with dense (RNDP) can achieve higher use efficiency (NUE) Jiangsu, east Three japonica inbred (JI) three indica hybrid (IH) cultivars were grown field experiment. Their yield, NUE, related traits compared under two cultivation treatments: conventional high-yielding practice (CHYP) RNDP. JI showed...
Light deficiency is a growing abiotic stress in rice production, however, few studies focus on shading effects grain yield and quality of east China. It also interesting to investigate proper nitrogen (N) application strategy for alleviating loss exposed light stress. A two-year field experiment was conducted explore the (non-shading from heading maturity) panicle N (NDP, decreased rate; NMP, medium NIP, increased rate) treatments yield- quality-related characteristics. Compared with...
The yield potential of japonica/indica hybrids (JIH) has been achieved over 13.5 t ha−1 in large-scale rice fields, and some physiological traits for advantage JIH japonica inbred (JI) indica hybrid (IH) were also identified. To date, little attention paid to morphological JI IH. For this reason, three JIH, JI, IH field-grown at East China (Ningbo, Zhejiang Province) 2015 2016. Compared with IH, had 14.3 20.8% higher grain yield, respectively, attributed its more spikelets per panicle...
Salinity is one of the primary abiotic stresses that cause negative physiological and biochemical changes due to oxidative stress caused by generation reactive oxygen species (ROS). The effect jasmonic acid (JA) as foliar spray humic (HA) soil amendment on growth attributes forage sorghum plants exposed salinity was investigated. Soil treated with NaCl at levels 0, 2, 4 g kg-1 dry (designated S0, S1, S2) 3, 6 HA HA0, HA1, HA2). were sprayed three JA levels, including 5, 10 mM JA. increased...
摘要:
Salinity stress is one of the most prevalent environmental factors that severely affect seed germination, early growth stages, and crop production. The present study was carried out to evaluate protective role β-aminobutyric acid (BABA) in alleviating salt chickpea (Cicer arietinum L.) varieties (Jabel Marra, Porgeg Shendi) under four concentrations NaCl solutions (0, 50, 100, 150 mM NaCl). Three levels 0.25, 0.50 mM) were applied. Germination seedling attributes measured. A high level...
Grain yield was greatly increased during the genetic improvement of japonica inbred rice since 1980s in Jiangsu, east China; thus, an improved plant morphology should be expected, considering that is a decisive factor determining grain yield. Twelve representative released from 1983 to 2013 were grown same fields 2019 and 2020. (p < 0.01) at 63.3 kg ha−1 year−1 across 2 years among cultivars different periods. The associated with spikelets per panicle. Single panicle weight, number...
摘要:
In order to study impacts of planting density mechanical-transplanting rice on lodging resistance and yield, a field experiment was conducted using indica-japonica hybrid Yongyou 2640, 1640 indica Fengliangy- ouxiang 1, Xinliangyou 6380 with six densities (A: 31.7 cm × 30 cm, B: 22.2 30.0 C: 17.1 D: 13.9 E: 11.7 F: 10.6 cm). The experimental results were as follows. With the increasing transplanting density, yield increased firstly decreased then, highest at both for in- dica-japonica Indica...
摘要:
It is widely reported that japonica/indica hybrids (JIH) have superior grain yield over other main varietal groups such as indica (IH) under sufficient resource inputs. To date, little attention has been paid to performance of JIH input-reduced practices, and whether could better IH practices. In this study, three varieties were compared in their related morpho-physiological traits two cultivation modes, i.e., conventional high-yielding method (CHYM) double reductions nitrogen rate planting...
