| The efficiency of sugar production in leaf tissue collected from canes of 2 varieties growing in nutrient solution containing different levels of Si was studied as well as the effect of Si in vitro on the activity of cane and yeast invertase and cane tyrosinase. Si deficiency decreased the rate of photosynthesis in symptom-free leaf tissue of cane whose older leaves were showing Si-deficiency symptoms. This effect was also obtained in completely symptomless Si-deficient cane growing under a Perspex roof. It would appear, therefore, that the lower efficiency of photosynthesis of Si-deficient leaves was not connected with the appearance of symptoms, i.e., degradative changes in leaf tissue. It was probably related to some other unknown function of Si in plant metabolism. The inhibition of invertase activity by Si in vitro was shown to be uniquely due to pH changes in the incubation medium brought about by the addition of sodium silicate. Si had no effect on cane and yeast invertase or cane tyrosinase activity in vitro. | |
