English: Nectarine (Prunus persica) fruit development over a 7½ month period, from early winter to midsummer; East Gippsland, Victoria, Australia.
  1. Bud formation can be observed on new growth on the plant (early winter) ( individual image)
  2. Flower buds clearly formed and leaves start to develop (early spring, ≈ 3 months) ( individual image).
  3. Flowers fully develop and are pollinated by wind or insects (early spring, ≈ 3½ months) ( individual image).
  4. If successfully pollinated, flowers die back and incipient fruit can be observed; leaves have quickly grown to provide tree with food and energy from photosynthesis (mid-spring, ≈ 4 months) ( individual image).
  5. Fruit is well developed and continues to grow (late spring, ≈ 5½ months) ( individual image).
  6. Fruit fully ripens to an edible form to encourage spreading of seed contained within by animals (midsummer, ≈ 7½ months) ( individual image).
