文摘

The competition for nitrogen between fruit and leaves at the spur level occurs during the whole season. Fruiting spurs had 50% less leaf area than non-fruiting spurs because they have smaller and less leaves. Defruited spurs significantly improved their survival and return bloom probabilities while compared to fruiting spurs. Defruited spurs were as likely to survive, but less likely to bloom than non-fruiting spurs.
