Acid and neutral in sugarcane milled were purified sixfold by precipitation with (NH4) 2SO4) at 20-40% saturation and 73-fold by Sephadex G-200 chromatography. Two major elution peaks on Sephadex, A1 and N1, corresponding to the isoenzymes... Read more.MS (University of the Philippines Los Baños)"In Vitro Inhibition of Sugarcance Invertase"
Acid and neutral invertases in sugarcane milled juice were purified six fold by precipitation with (NH4)2SO4 at 20=40% saturation and 73-fold by Sephadex G-200 chromatography. Two major elution peaks on Sephadex, A1 and N1 corresponding to... Read more.MS (University of the Philippines Los Baños)"Influence of Herbicides on Sclerotium Damping-Off in Tomato."
Laboratoty and greenhouse experiments were conducted to determine the effect of herbicides on damping-off in tomato. Treatments with napropamide (2.0 kg/ha), butralin (1.5 kg/ha) and napromide plus butralin combination (1 + 1 kg/ha) on...
