4种植物生长物质及温度胁迫对绿豆黄化幼苗肌醇磷脂代谢的影响

利用放射性标记和薄层层析（TIC）分离发现2,4－D,GA3和6－BA可不同程度地促进肌醇－1,4,5－三磷酸（IP3）水平的增加．在最适浓度下的作用效果是：GA3＞2,4－D＞6－BA．但脱落酸（ABA）没有引起IP3含量的变化．低温（0℃）和高温（35℃）胁迫亦引起IP3含量的增加．2,4－D,GA3,6－BA和温度胁迫的共同处理对IP3含量的增加有协同作用．表明2,4－D,GA3,6－BA和温度胁迫促进绿豆黄化幼苗肌醇磷脂代谢,ABA也许不参与绿豆黄化幼苗肌醇磷脂代谢．

Rapid determination of protein in plant material by flow injection spectrophotometry with trinitrobenzenesulfonic acid

The rapid determination of protein in plant material based on spectrophotometric determination of amino acids in protein hydrolysates with trinitrobenzenesulfonic acid has been adapted to flow injection analysis. With the manifold described, a routine sampling rate of 120 samples/h is possible, though this, as well as sensitivity, can easily be varied. The method was calibrated against the Kjeldahl method and a good correlation was obtained between the two methods over a wide range of protein values for beans.     

The Kissinger law and isokinetic effect: Part II. Experimental analysis

On the basis of copper sulphate pentahydrate thermal dissociation, for analyzed reactions I to IV, 6 thermokinetic equations was discussed. Arrhenius law parameters were determined and the isokinetic effect (IE) and Kissinger law appearing was analyzed. It was found that only dependence resulting from isokinetic effect, in the form k _m=q/T _m, relates to the suitable thermokinetic Eq. (2) and Kissinger law in modified form (14). The confirmation was made that the possibility of determining the averaged activation energy from thermokinetic equations using suitable correction coefficients exists.This revised version was published online in November 2005 with corrections to the Cover Date.
