Effect of pore-size on penetration by sugarcane roots

Abstract

Sugarcane cultivars Co 1148 and CoJ 64 were grown in sand on sieves having average opening of 1000, 500 and 250 ?m. Pore-size of sieves markedly influenced the penetration by sugarcane roots. Only 2.35 and 3.3% roots of Co 1148 and CoJ 64, respectively, could pass through 250 ?m openings.
