(1) SFE could elevate the activity of invertase in vivo during the periods of flowering and pod - filling .

(2) The activity of invertase is negatively correlated with sucrose content and the correlation between phosphorylase activity and sucrose content is positive.

(3) Variations of peroxidase, sucrose invertase and urease activity in soil from Eucalyptus coppice forest, Eucalyptus newly planted forest, shrub grassland and masson pine forest have been investigated.

(4) The activity of Soil urease, acidphosphotase and invertase weakened with increase of soil depth.

(5) It is very interesting that soil invertase is activated and its activity is enhanced at low concentration of dimehypo, and then is inhibited at high concentrations.

(6) Invertase can exist as active monomer ( light invertase ) or as an aggregated active form ( heavy invertase ).

(7) Invertase plays an important role during the sucrose metabolism in higher plant.

(8) Effect of ethanol concentration on the soil invertase activity and effect of different substrate(saccharose) concentrations on the relationship between invertase activity and ethanol were studied.

(9) The highest urease and invertase activities were observed at jointing stage, while the highest acid phosphatase activity at the huge bellbottom period.

(10) Meanwhile, it was subclassed into plant vacuolar invertase by phylogenetic relation analysis.

(11) It is suggested that a new member of citrus acid invertase gene family was obtained.

(12) Red Globe grape was used to study the effect of 6BA and zeatin on sugar accumulation and invertase activities.
