Other claims from this paper (15)

Observation LAIs of 3.3 and 3.6 with bud load 680−700 gave optimum constant yield over 90 kg per vine in both years.
Observation Those kiwifruit vines had good average fruit weight over 100 g.
Observation Those vines had high fruit quality in both years and good return bloom the following season.
Intervention effect LAI 2.6 reduced yield by 18.5% compared with LAI above 3.1 in the treatment year.

Intervention effect LAI 1.8 significantly decreased fruit soluble solids and reduced subsequent fruiting shoots and fruits per shoot.
Intervention effect LAI 3.1 produced small variations in yield and fruit weight during defoliation year.
Intervention effect LAI 3.1 significantly reduced next-season yield by 14 kg per vine.
Observation At LAI 2.6 nearly all fruits ripened without significant fruit drop.
Observation At LAI 1.8 nearly all fruits ripened without significant fruit drop.
Mechanism Low LAI increased and extended fruit sink strength, restricting vine growth and reserves.
Recommendation The authors recommend LAI above 3.3 and leaf area-fruit ratio above 600 cm2 per fruit for regular growth, yield, fruit quality and return bloom.
