Experiment results showed that Imazalil(500g/L) emulsifiable concentuates(EC) had a significant role in inhibiting Penicillium italicum Wehmer and Penicillium digitatum Saec on orange. The EC_(50) of Imazalil on P.italicum and P.digitatum was 0.0136mg/kg and 0.0129mg/kg respectively.
1. 242 samples of satsuma mandarin (Citrus unshiu Marc), tangerine (C. reticulata Blanc), sweet orange (C. sinensis Osb.) and pummelo (C. grandis Osb.) were randomly collected from ten counties of Hubei, Hunan, and Jiangxi.
When excited with UV light ( λ =254 nm), Y 4Al 2O 9:Eu 3+ exhibits the orange emission band at λ =590 nm due to the 5 D 0→ 7 F 1 transition and the red emission band at λ =610 nm due to the 5 D 0→ 7 F 2 transition.
In a range of pH5.0～6.2,Cr(Ⅵ) can react with TPY to form a orange product in HAc-NaAc medium. Maximum absorbance is at 367 nm with molar absorptivity of 1.72×10 5L·(mol·cm) -1 .Beer’s law is obeyed in the range of 1.3～76 μg Cr(Ⅵ)/L.
In the presence of Mn(Ⅱ) and Tween-80,V(V) reacts with DAOBM to form an orange product in a buffer solution of H3PO4 (1+10). Maximum absorbance is at 490 nm with molar absorptivity of 1.55×106L·mol-1,cm-1.Beer's law is obeyed in the range of 0.1-0.9μgV/25ml.
The photocatalytic degradation of methyl orange (MO) in aqueous solution under 365 nm irradiation on TiO2 and Ag/TiO2 thin films was investigated.
Effects of arbuscular mycorrhizal fungi on leaf solutes and root absorption areas of trifoliate orange seedlings under water str
The effects of the arbuscular mycorrhizal (AM) fungus Glomus mosseae on plant growth, leaf solutes and root absorption area of trifoliate orange (Poncirus trifoliata (L.) Raf.) seedlings were studied in potted culture under water stress conditions.
mosseae inoculation on trifoliate orange seedlings under 20% and 16% soil water content were more significant than under 12% soil water content.
