dc.descriptionDrought stress was imposed on 2 cassava cv. (M Col 22 and M Mex 59) at Santander de Quilichao (Colombia), by withholding rainfall from field plots (plastic covers were placed over the soil surface) for 10 wk, commencing when crops were 12 wk old. The plants were then allowed to recuperate until the expt was terminated at 10 mo. Harvests were taken at intervals through the growth cycle and were supplemented with measurements of fine root distribution, leaf production and senescence, soil and plant water status, and stomatal response. As a result of the stress, the late-developing cv. M Mex 59 actually improved its yield at 10 mo over the controls. An explanation for the behavior of both cv. is sought in the relative effects of water shortage on DM production and allocation, canopy dynamics and internal plant water relations. (AS)
dc.descriptionSe impuso estres de sequia en 2 cv. de yuca (M Col 22 y M Mex 59) mediante el impedimento de lluvias en las parcelas (se colocaron cobertores plasticos sobre la superficie del suelo) durante 10 semanas en Santander de Quilichao (Colombia), comenzando cuando los cultivos tenian 12 semanas; luego se permitio la recuperacion de las plantas, hasta que se finalizo el experimento a los 10 meses. Las cosechas se efectuaron con intervalos a traves del ciclo de crecimiento, y se suplementaron con mediciones de la distribucion de las raices mas finas, la produccion foliar y la senescencia, el status del agua del suelo de la planta y la respuesta estomatal. Como resultado del estres, el cv. de desarrollo tardio M Mex 59 mejoro su rendimiento sobre los testigos a los 10 meses. Se busca una explicacion del comportamiento de los 2 cv. en cuanto a los efectos relativos de la escasez de agua sobre la produccion y distribucion de la MS, la dinamica de la parte aerea y las ralaciones internas del agua de la planta.
