Abstract Abiotic stresses, including cold and drought, negatively affect maize ( Zea mays L.) seed field emergence later yield quality. In order to reveal the molecular mechanism of resistance abiotic stress at germination, global transcriptome high- vigour variety Zhongdi175 exposed cold- drought- was analyzed by RNA-seq. comparison between control different stressed sample, 12,299 differentially expressed genes (DEGs) were detected, which 9605 7837 DEGs identified under stress,...

Abstract Crop performance is seriously affected by high salt concentrations in soils. To develop improved seed pre-sowing treatment technologies, it crucial to improve the tolerance of germination. Here, we isolated and identified strain Bacillus sp. MGW9 developed biostimulant MGW9. The effects biopriming with maize ( Zea mays L.) under saline conditions were studied. results show that has characteristics such as tolerance, nitrogen fixation, phosphorus dissolution, indole-3-acetic acid...

In recent years, the sweet potato cultivar Jishu 25 has exhibited good characteristics for starch processing in northern China. The storage root dry matter yields of this can exceed one ton per mu (1/15 a hectare) at nitrogen (N) rates 60–90 kg ha-1 based on soil nutrient content. However, effect N fertilizer physicochemical properties starches isolated from not been reported. order to evaluate these effects, three different rates, 0 (control, N0), 75 (N1), and 150 (N2), were selected field...

The effect of canola (Brassica napus L.) seed germination under illuminated and dark environments on the total concentration composition tocopherols phytosterols in seedlings extracted oil were investigated. During first 10 days germination, a decrease gamma-tocopherol was offset by an increase alpha-tocopherol, indicating interconversion these isomers. From day to 20 illumination, there net alpha-tocopherol suggesting synthesis new tocopherols, whereas no dark. Tocopherols mainly...

Abstract Three maize cultivars with different endosperm types (flint, semiflint, and dent cultivars) were studied to characterize vitreous flour properties compared those of floury from the same kernels. Vitreous had higher amylose protein contents, lower starch content, percentage large granule, bigger mean diameter iodine capacity, trough viscosity final setback, swelling power, peak breakdown, time pasting temperature than counterpart flour. X‐ray diffraction analysis indicated typical...

The morphogenesis of crops is critical to their yield performance. COP1 (constitutively photomorphogenic1) one the core regulators in plant and has been deeply studied Arabidopsis thaliana. However, function maize still unclear. Here, we found that mesocotyl lengths zmcop1 loss-of-function mutants were shorter than those wild-type B73 darkness, while lines with ZmCOP1 overexpression longer B104. height was both short- long-day photoperiods. Using transcriptome RNA sequencing technology,...

Grain texture is an important trait in corn ( Zea mays L.) grain quality, influencing shipping and processing characteristics, susceptibility to insects, flour cooking properties. The objective of this study was evaluate anatomical physiological factors affecting for three types differing endosperm (Dent with floury‐textured endosperm, popcorn sweet vitreous‐textured endosperm). cell number size, diameter starch granules the distribution protein bodies during development were determined....

The root quality of sweet potato cultivated during the summer season is poor in northern China; thus, this study was conducted to determine whether could be improved through mulching with plastic film (MPF). effect MPF on starch and its composition, activity synthesis enzymes, other quality-related parameters were investigated two purple flesh cultivars, Jishu 18 Ayamurasaki (Aya). results indicated that dry matter, anthocyanin content, adenosine triphosphate (ATP), content higher both...

Abstract Low planting density and irrational nitrogen (N) fertilization are two common practices in conventional cropping of smallholder maize production Huanghuaihai region China. A 2-year field experiment was carried out to study the effects N application on phenology, dry matter accumulation, profit, yield, uptake efficiency indices. The experiments included three levels (120 kg ha −1 , N1; 180 N2; 240 N3) densities (60,000 plants D1; 75,000 D2; 90,000 D3). Increasing input delayed...

As a rare, endemic, important, and salt-sensitive medicinal plant species in China, Cynanchum bungei Decne seeds were treated to germinate with distilled water (control) or NaCl solutions the presence absence of nitric oxide (NO) donor sodium nitroprusside (SNP) investigate effects exogenous NO on seed germination, seedling growth, antioxidant enzyme activities under salt stress. Sixty m significantly inhibited germination growth C. . Exogenous SNP alleviated stress dose-dependent manner, as...

Cynanchum bungei Decne is a rare, endemic, and important medicinal plant species in China. Seed germination early seedling growth of large seeds (greater than 7 mm) small (smaller were investigated at three temperatures (15, 20, 25 °C) both continuous light alternating light/dark photoperiods to determine seed propagation requirements. Photoperiod significantly affected growth. Germination 12:12-h photoperiod performed better light. Temperature had significant effect on index (GI), vigor...

The effect of germination and growth under illuminated dark environments on canola seed reserves was investigated. Depletion proteins lipids in whole seedlings their top (leaf/cotyledons) bottom parts (stem/roots/seed coat) independent light, whereas the protein solubility increased at a faster rate an environment than dark. A rapid increase free fatty acids but net decrease dry matter content grown observed. due to photosynthetic biomass accumulation.

Abstract Crop performance is seriously affected by high salt concentrations in soils. To develop more new seed pre-sowing treatment technologies it crucial to improve the tolerance of germination. Here we isolated and identified strain Bacillus sp . MGW9 developed biostimulant (SB-MGW9) strain. Effect biopriming with SB-MGW9 maize ( Zea mays L.) under saline condition were studied. The results showed that has characteristics tolerance, nitrogen fixation, phosphorus dissolution,...

In recent years, fuel-powered multi-rotor unmanned aerial vehicles (UAV) have been increasingly applied in high-stalk crops, because of their stronger rotor wind field. More and more attention has paid to UAV application performance crops. Maize is a kind typical crops it also one the main food its planting area ranks third inChina, second only wheat rice. this study, field test was conducted investigate maize crop protection UAVs droplets deposition effect on different canopies leaf...
