| Abstract:
Flesh firmness and percentage total soluble solids of kiwifruit at harvest, and after cold storage were compared for three 'Hayward' selections on different rootstocks four and five years after grafting. There were significant scion and rootstock effects (P ≤ 0.05) on fruit firmness and total soluble solids at harvest. 'Hayward' fruit from own-root vines had lower percentage sugar at harvest and after cold storage than fruit from most rootstocks. 'Hayward' 'C' fruit on clonal rootstocks of two genotypes was firmer after 15 weeks cold storage than fruit on five other rootstocks. Vine yield was not associated with fruit firmness at harvest and after cold storage. | |
