| Description | Die langgtermyneffek van swart haelnette (20%- beskaduwingseffek) op tafeldruiwe (kultivars Pirobella, Bien Donné, Ronelle en Italia) se botpersentasie, oogvrughaarheid, lootmassa, oesmassa, trosmassa, korrelmassa en - bars, asook suikerkonsentrasie (totale oplosbare vastestowwe), suurkonsentrasie (titreerbare sure) en pH is ondersoek. Haelnette het die hotpersentasie en vrughaarheid betekenisvol verlaag. Reproduktiewe groei in terme van trosmassa en opbrengs onder die haelnette neig om hoër te wees as sonder haelnette, terwyl korrelmassa nie beïnvloed is nie. Korrelbars neig om laer onder haelnette te wees. Die suikerkonsentrasie en pH van die korrels onder die nette was betekenisvol laer, terwyl die suurkonsentrasie hoër was. The long term effect of black hail netting (20% shading) on budding percentage, but fertility, cane mass, yield, bunch mass, berry mass and berry cracking as well as sugar concentration (total soluble solids), acid concentration (titratable acidity) and pH of the berry juice of table grapes (cultivars Pirobella, Bien Donne, Ronelle and Italia) was evaluated. Budding percentage and bud fertility were significantly reduced by hail netting. Reproductive growth in terms of yield and bunch mass seemed to be higher under hail netting compared to direct sunlight, while berry mass was not affected. Berry cracking tended to decrease under hail netting. Berry sugar concentration and pH decreased significantly under hail netting, while the acid concentration increased. | |
