Research Areas

Peach (Prunus persica L. Batch)

Aims

  • Collection, evaluation and reservation of peach cultivars and rootstocks.
  • Improvement of peach cultivars and rootstocks.
  • Frost protection, nutrition- fertilization, pruning, thinning.
  • Propagation.
  • Organize and participate in peach tree growing training.

Main Results

  • Many peach cultivars and rootstocks have been evaluated for morphological and chemical characteristics (color, soluble solids, total acids, total phenols, anthocyanins, carotenoids and ascorbic acid contents, total antioxidant capacity and browning potential), yield, nutritional needs, resistance to frost, diseases and insects.
  • New improved clingstone cultivars were created such as PI-Α37, PI.-ΙΒ42, PI.-Ε45 and PI.-Α39, which have been realised for cultivation in Greece.
  • New improved late maturing peach and nectarine cultivars were created such as PI.-14, PI-73, PI.–314 and PI.–ΒΠ., which have been realised for cultivation in Greece.
  • New improved rootstocks were created such as PI-PR204/84 and PI.-ΚΙΔ2. They have good replanting characteristics, since cultivars grafted on those rootstocks gave better fruit quality characteristics, compared to the widely used GF 677.
  • Many methods for frost protection have been evaluated. The application of GA3 and molasses gave good protection.
  • The technology of Integrated Fruit Production system was studied with emphasis on finding best cultivars, appropriate fertilization, irrigation, pruning and thinning.
  • Many research papers in international and Greek journals were published.
