Effect of four water regimes on performance of glasshouse-grown nursery apple trees

Abstract

Increasing the frequency of water application to potted nursery apple trees from three-weekly to fortnightly, weekly and daily produced a significant positive effect on six growth indices but had no effect on final shoot number. Three commonly used indices of growth in the field, namely girth increment, total shoot growth and final shoot number, are examined in relation to total dry-weight increment.
