Different treatments were tested in the aloe field and soil in reservoir region of Three Gorges,the result showed:both seedlings and soil disinfected with Ruidumei and nanometer silicon could effectively control aloe seedling diseases;while a contrast experimenta about the effect of nanometer silicon against Ascochyta tini on aloe was studied.

After the colony shape feature observation experiments, the colony growth speed experiments , the spore - producing observation and conidial germination experiments on the parasitic fungus Aschersonia sp.

Comparative studies on the growth of Sphaeropsis sapinea isolates;

Comparative studies on the morphology of Sphaeropsis sapinea spores and mycelia;

Inoculations revealed that the Chinese isolates of Sphaeropsis sapinea were similar to American A isolates in pathogenicity which was much nore aggressive than B isolates.

In this paper, pharmacological and fluorescence ratio photometry was applied to investigate the effect of proton pump activator fusicoccin and inhibitor sodium vanadate on Arabidopsis pollen germination and cytosolic calcium concentration in pollen cells.

In order to verify the role of proton pump in stomatal movement,the effect of its activator(fusicoccin)and inhibitor(sodium vanadate)on stomatal movements and .
