Leaf-area ratio in relation to yield in sugarcane
1987
Singh, S. | Rao, P.N.G. (Sugarcane Breeding Inst., Coimbatore (India))
A 3-year experiment showed that leaf-area ratio declined steadily with age of 6 varieties of sugarcane. Low-yielding 'Co 1148' and 'CoJ 64' had higher leaf-area ratio than the high-yielding 'Co 419', 'Co 740' and 'Co 7219'. At formative, elongation and maturity stages of crop, the leaf-ratio showed negative and significant correlation with cane yield and the relationship was highly consistent over the years. The leaf-area ratio would be used as an index for yield potential in sugarcane
