- W1497996306 abstract "R E S U M E N El periodo de vegetacion activa durante el ano 1970 comprendio cuatro ciclos completos (hasta plena floracion) mas un quinto ciclo en que las plantas no pasaron del estado vegetativo. La duracion de los tres ciclos intermedios fue inferior en el cultivar Du Puits. Las curvas de crecimiento tuvieron la clasica forma sigmoide. En los tres ciclos completos estudiados, las producciones medias diarias maximas, en ambos cultivares, se dieron en la fase de gemacion floral, aunque el de Aragon la alcanzo en el segundo ciclo (179,7 Kg. s.s./ha.) y el Du Puits en el tercero (163,2 Kg. s.s./ha.) El incremento marginal, en cambio, fue maximo en la fase vegetativa del segundo ciclo de la alfalfa Aragon (247,8 Kg. de s.s./ha.) y en la fase de gemacion del tercer ciclo de la Du Puits (220,5 Kg. de s.s./ha.). S U M M A RY From each of five plots with Latin square design 5x5 cuttings have been succesively taken at 20-30 cm. and 30-40 cm. height, pre-bud, early flower and full flower stages through the growing season from March to October. During this time both cultivars completed four cycles of vegetation (full flower). The plants of both cultivars did not reach the flower stage after the fourth cycle. Du Puits cultivar reached the flower stage about 8 days before than Aragon cultivar during the 2nd, 3rd and 4th cycles studied. Mean daily yields (total D. M./number of days) were maximum in both cultivars at bud stage (179,7 Kg/D. M./Ha.) at 2nd cycle the Aragon cultivar (163,2 Kg/D. M./Ha.) but at the 3rd cycle the Du Puits cultivar. The mean daily marginal increase of D. M. between one and the following cut (D. M. produced/ n.° of days) reached a maximum at the pre-bud stage of the 2nd cycle in the Aragon cultivar (247,8 Kg/D. M./Ha.) and at the full bud stage of the 3rd cycle in Du Puits cultivar (220,5 Kg/D. M./Ha.). The growth curves were always of the typical sigmoide type." @default.
