Effects of Age on the Elemental Nutrients of Celosia Cultivars
Published online by Cambridge University Press: 03 October 2008
Summary
Studies on the effects of age on the elemental nutrients contained in Celosia argentea cultivars showed that calcium, phosphorus and potassium decreased with age, the highest content of those elements occurring in the leaves between 5 and 7 weeks after sowing. Other elements, notably manganese and magnesium, increased up to 15 weeks after sowing. An anthocyanin-pigmented cultivar contained more iron, sodium and copper than green cultivars. Breeding potentials of the cultivars in terms of elemental nutrients are discussed, and harvesting the leaves of all cultivars 5 to 9 weeks after sowing is recommended.
