| dc.description | The time-course for induction of growth, sucrose, and enzyme changes by Polaris (N,N-bis [phosphonomethyl] glycine), a commercial sugarcane ripener marketed by Monsanto Agricultural Products Company, was studied with early-juvenile sugarcane propagated by sand culture. The ripener was administered as an aqueous foliar spray containing 3000 p/m active ingredient. Plant samples were harvested just prior to treatment and from 8 h to 10 days thereafter. Acid invertase was significantly repressed within 24 hand sucrose increased in both leaf and expanding stem tissue within 48 h. The enzymes trehalase and ATP-ase declined in expanding stem tissue by the fourth and tenth day, respectively. Soluble protein was significantly repressed from the seventh day onward. Significant growth repression was first recorded at 7 days. The time-course of Polaris action is discussed in the context of spatially- and biochemically-discrete tasks to be performed within an early-juvenile model. | en-US |
| dc.description | El tiempo que Polaris (N, N-bis [fosfonometil] glicina) toma para la inducción de cambios en el crecimiento, la sacarosa y los enzimas se examinó en plantitas de caña de azúcar sembradas en arena. El compuesto comercial madurativo se aplicó en una aspersión foliar acuosa que contenía 3,000 p.p.m. del ingrediente activo. Muestras de las plantas se cosecharon inmediatamente antes de la aplicación y de 8 horas a 10 días más tarde. La invertasa ácida disminuyó significativamente dentro de 24 horas y la sacarosa aumentó tanto en las hojas como en las cañas inmaturas dentro de 48 horas. Los enzimas trehalasa y ATP-asa, y la proteína soluble fueron restringidos en las cañas inmaturas a partir del cuarto día. Una restricción significativa en crecimiento se obtuvo al séptimo día. La rapidez de acción de Polaris se discute dentro del contexto de discretas funciones bioquímicas y espaciales que pueden tener lugar en una planta joven tomada como un sistema modelo. | es-ES |
