Nursery Production in AustraliaLot of nurseries come & go Mainly due to waiting timeOnly two large commercial nurseries Others supplying own needs General fruit tree nurseries
Nurseries & Orchard Rejuvenation• Obviously nurseries will play a big part – Commercial nurseries – Nursery for own use• Rejuvenation – Existing varieties – New varieties from breeding program• I believe anybody propagating the new varieties should require approval – AMS
Nurseries & Orchard Rejuvenation• Based on current methods of propagation nurseries will require a large source of scion wood. – Preferably close to nursery – Trees need to be a few years old at least – Varieties clearly identified – These trees can’t be data trees• Release of Regional Variety Trial scion wood in the late 80’s??????????
Nurseries around the World• Poor nursery stock• Poor orchards trees• Poor performance• Major influence on quality Potting Mix Water quality
Nursery Accreditation• The AMS has no official “Accreditation scheme”• Nursery Industry – N. I. A. S. A.• Strong demand = back yard nurseries Can lead to poor qualityI like the SAMAC system of “affiliated nurseries”
Nursery R & D• Australian industry spend $2m / year on R&D• Zero $ on nursery R & D• Why do the two largest producing countries propagate in complete opposite ways?• Why do we still use H2 rootstock?• Cuttings – Large numbers would be difficult sell. !!!!
Nursery R & D• Why don’t we “mini” graft?• Producing nursery stock is expensive & not very profitable. – Researched Avocadoes, Citrus etc – Most sell at higher price & quicker to grow• Perhaps there is an opportunity for joint R & D between countries!!!!!!!!!
