Effect of mycorrhizal inoculation and phosphorus fertiliser on the growth of hardwood cuttings of kiwifruit (Actinidia deliciosacv. Hayward) in containers

摘要

Kiwifruit (Actinidia deliciosa(A. Chev) C. F. Liang et A. R. Ferguson var.deliciosacv. Hayward), hardwood cuttings were grown in peatpumice mix amended with 3 rates of phosphorus (P) fertiliser and 5 rates of mycorrhizal inoculum for 130 days in a heated glasshouse. P fertiliser increased shoot length and weight by up to 170 and 145 respectively. Mycorrhizal inoculation increased shoot length and weight by 294 and 265 respectively, with no significant interaction between inoculation and fertiliser. Optimum plant growth was achieved with 1000 g superphosphate and 50 litres mycorrhizal inoculum per m3 of potting mix.
