Taking two peanut varieties Huayu 17 and Tangke 8 as test objects, a soil column culture experiment was conducted in a rainproof tank to study the peanut root morphological development and physiological characteristics at late growth stages under moderate drought and well-watered conditions. Tanke 8 had more developed root system and higher yield and(More)
IR-online detector, React IRTM 4000, was used to monitor the synthesis of N,N-diphenyl urea from urea and aniline. The concentration changes of the reaction components were obtained according to the characteristic IR absorbance changes of the reactants (urea and aniline) at 1 420 and 1 270 cm(-1) respectively, the intermediate product (monophenylurea) at 1(More)
BACKGROUND Multivariate models with a combination of variables can predict disease more accurately than a single variable employed alone. We developed a logistic regression model with a combination of variables and evaluated its ability to predict lung cancer. MATERIAL AND METHODS The exhaled breath from 57 patients with lung cancer and 72 healthy controls(More)
A total of two hundred peanut varieties (lines) were exposed to different salt concentrations under pot cultivation, to evaluate salinity tolerance by indices such as emergence, morphology and biomass accumulation from emergence to seedling stage. The results showed that, as the salinity concentration increased, the emergence time was prolonged, plant(More)
