| Abstract: | The activities of Mg~(2+)--ATPase and Ca~(2+)--ATPase in leaves of 9 sugarcanegenotypes were closely related to early maturity and high sugar content. It was foundthat Chunnee, an original cultivar (Saccharum sinense), showed the highest enzyme activi-ties, followed by Black Cheribon (S.officinarum). Jinjiang Spontaneous Cane, a wildspecies (S.spontaneum), had the lowest enzyme activity and the lowest sugar contenttoo. The enzyme activities of 5 hybrid cultivars ranged between those of Chunnee andJinjiang Spontaneus Cane, and those of the early cultivars were obviously higher thanthose of the middle-late ones. Fuying 79/8, a cultivar with the highest enzyme activi-ties, was also the earliest. There were detectable activities of Mg~(2+)--ATPase and Ca~(2+)--ATPase in the stalk,leaf blade, leaf sheath and root of young plants of Fuying 79/8 and POJ2878. Butthose in leaves showed the biggest difference between the two genotypes. The activitiesof Mg~(2+)--ATPase and Ca~(2+)--ATPase in the leaf of Fuying 79/8 were 4.7 and 1.7times higher than those of POJ2878, respectively. |
