Storage and postharvest quality of apples following application of paclobutrazol to trees.

ABSTRACT :

 

Braeburn and Oregon Spur Delicious/MM.106 apple trees growing under an ultra-high density planting system at Lincoln University Horticultural Research Area were treated with paclobutrazol as a soil drench. The first application was made at 0 and 250 mg paclobutrazol/tree in 1989 and was followed with further applications in 1990 and 1993. Fruit quality and storage potential were assessed 3 years after the first application and one year after the second application. Data on quality variables such as fruit weight, fruit colour, fruit length:diameter ratio, flesh firmness, total soluble solids and storage disorders were collected following different times of harvest and storage for the years 1993 and 1994. Storage was in a controlled environment at 10 deg C for up to 80 days, by which time fruits were showing major quality reductions. The advantages of preharvest paclobutrazol application to improve quality variables and storage potential for apples is discussed.
