Effect of plant growth regulators on sugarcane production in Taiwan

Effect of plant growth regulators on sugarcane production in Taiwan. Yang, Pai Chun (Agron. Head Agron. Dep., Taiwan Sugar Res. Inst., TSC, Tainan, Taiwan). FFTC Book Ser., 34(Plant Growth Regul. Agric.), 114-26 (English) 1986. CODEN: FBSEDX. ISSN: 0253-9616. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Application of Cycocel [999-81-5] (10 kg a.i./ha), IBA [133-32-4] (100-200 ppm) and Ethrel [16672-87-0] (1000 ppm) on cane stubble during the winter season induced ratoon shoots and tillers at an early growth stage, resulting in increase of ratoon untreated yield by 3-12% vs. the untreated check. Spraying of GA3 [77-06-5] at 100-200 ppm during the cool season resulted in a significant increase in joint length and wt. of cane stalks, with a greater response in stalk elongation in younger cane. There was no substantial difference in cane quality for GA3-treated cane if harvested 3 mo after treatment. Sugarcane flowering was effectively controlled by application of CMU [150-68-5] at 5.6 kg/ha or Reglone [85-00-7] at 0.75/ha during late August and early Sept., resulting in a sugar yield increase in the late milling season. Three applications of GA3 (100 pm) in August to Oct. also prevented sugarcane flowering. Aerial applications of Polaris [2439-99-8] (4.5 kg/ha), Embark [53780-34-0] (2.3 L/ha), and Ethrel [16672-87-0] (2 L/ha) 6-10 wk prior to harvest consistently increased sucrose [57-50-1] in sugarcane.In this experiment, several chemicals are used like 85-00-7 and 999-81-5 In large-scale field trials, the cane treated with these ripeners had increases of about 8-10% in available sugar. There was no adverse effect on stalk d., stalk height and cane yield of the succeeding ratoon. .

Glyphosine inhibits maize leaf phosphoenolpyruvate carboxylase

Glyphosine inhibits maize leaf phosphoenolpyruvate carboxylase. Podesta, Florencio E.; Gonzalez, Daniel H.; Andreo, Carlos S. (Cent. Estud. Fotosinteticos Bioquim., Univ. Nacl. Rosario, Rosario 2000, Argent.Several reagents with their cas registry numbers 9067-77-0 and 56-40-6 are used here.). Plant Cell Physiol., 28(2), 375-8 (English) 1987. CODEN: PCPHA5. ISSN: 0032-0781. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Glyphosine [2439-99-8] inhibited maize leaf phosphoenolpyruvate carboxylase [9067-77-0] competitively with respect to phosphoenolpyruvate [138-08-9]. The inhibition was dependent on glyphosine concn. and pH. Glycine [56-40-6], but not glucose-6-phosphate [56-73-5], protected the enzyme from the effect of glyphosine. A related compd., glyphosate [1071-83-6], produced little or no inhibition. Phosphoenolpyruvate carboxylase could be one of the targets of glyphosine action, causing growth inhibition as previously reported. .
