According to the statistical test,all of these three kinds of models fitted the experimental data quite well,and statistical analysis showed that the linear model was the best,whether the remnant food in stomach was expressed by wet weight or dry weight. When the remnant food in stomach was expressed by wet weight,the model was Y=92.93-3.33 t(R2=0.94,P<0.001);
Experiment results show that the optimum extraction parameters are:36% volume fraction of ethanol,2.0% dry weight of cellulase,liquid to solid ratio of 52∶1,pH 5.5,enzyme digestion temperature of 50 ℃ and extraction time of 5 h. Under such conditions the leaching rate of total flavones is up to 7.144%.
The results indicated that the optimum concentration of NdCl3 was 20～40mg/L,which can promote the growth of planlets(such as the number and length of roots,leaves and the planlet height) and increase the dry weight of planlet and chlorophyll content.
Seed weight per mu has extreme signficantly positive correlation with total dry weight of plants (r=0.955~**,n=8) and appears to be linear relation with dry weight of plants, and the regression equation is Y=-144.59+0.73x.
It was indicated by the results that under the stress of 150 mmol/L NaCl,the seedling emergence percentage and the dry weight of plant at 2 leaf stage were decreased significantly in the seed soaking treatments with 1 0～3 0 mg/L DPC and 20～60 mmol/L CaCl 2,hence seedling growth was retarded But 0 5 mg/L DPC and 10 mmol/L CaCl 2 didnt have the effect.
结果表明 ,在 15 0 mm ol/ L Na Cl胁迫下 ,除 0 .5 mg/ L DPC和 10 mm ol/ L Ca Cl2 浸种处理以外 ,1.0～ 3.0mg/ L DPC和 2 0～ 6 0 m mol/ L Ca Cl2 浸种均显著降低棉花发芽势、出苗率和二叶期棉苗干物重 ;
Results: According to CHD the incidence of hypotension is 16.30%, the incidence of cramps is 14.13%, to PHD the hypotensim incidence is 4.34%, the cramp incidence is 3.98%, the hypertension incidence during and after CHD treatment is decreased 39.97% and estimated dry weight (EDW) is also decreased after PHD treatment.
Dry weight of roots and total amount of salvianic acid A and protocatechuic aldehyde of Salvia miltiorrhiza supplied with mix of rape cake and inorganic fertilizer(N 1.25 g,P 0.99 g,K 1.46 g)were the highest.
The treatment N_0P_(125)K_(37.5) was the best for foliage-usage forest cultivation with total biomass dry weight of 438 g, root biomass dry weight of 192 g, stem and branch biomass dry weight of 159 g, leaf biomass dry weight of 88 g, which were respectively (83.42%)、60.10%、98.13% and 113.44% higher than that of non-fertilizing treatment.
mosseae increased plant height, stem diameter, leaf area, shoot dry weight, root dry weight and plant dry weight, when the soil water content was 20%, 16% and 12%.
When the concentration of Cd in the soil was 10 mg/kg and the concentration of As was 50 mg/kg, the highest growing height of the plant was up to 35.9 cm and the dry weight of the shoots was up to 2.2 g/pot, respectively.
The content of glucose in tomato fruits of cv.Ukrainskii teplichnyi increased from 3.62 to 11.24% per unit dry weight.
The yields of superoxide dismutase and ajmaline were 180 mg/kg biomass and 16.5 g/kg dry weight, respectively.
zonarus), whereas the corresponding consumption levels for cocultures ofMycelia sterilia and Trichoderma reesei equaled 70 and 45%, respectively (total loss of dry weight ranged from 55 to 60%).
