caption_attribution_description: English: Nectarine (Prunus persica) fruit development over a 7½ month period, from early winter to midsummer; East Gippsland, Victoria, Australia. Bud formation can be observed on new growth on the plant (early winter) (individual image) Flower buds clearly formed and leaves start to develop (early spring, ≈ 3 months) (individual image). Flowers fully develop and are pollinated by wind or insects (early spring, ≈ 3½ months) (individual image). 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). Fruit is well developed and continues to grow (late spring, ≈ 5½ months) (individual image). Fruit fully ripens to an edible form to encourage spreading of seed contained within by animals (midsummer, ≈ 7½ months) (individual image). Français&#160;: Développement d'une nectarine sur une période de 7,5 mois, du début de l'hiver au milieu de l'été. Est du Gippsland, Victoria (Australie). Formation d'un bourgeon sur une tige de l'année (t0, début de l'hiver). Différentiation de l'aspect des bourgeons floraux et végétatifs (t + 3 mois, début du printemps). Les fleurs sont ouvertes et sont fécondées par le pollen amené vent et les insectes (t + 3,5 mois, début du printemps). Formation des fruits. Le feuillage est pleinement développé et permet la photosynthèse (t + 4 mois, milieu du printemps). Fruit en plein développement (t + 5,5 mois, fin du printemps). Le fruit murit, devenant comestible, ce qui permet de répandre au loin la graine qu'il contient.(t + 7,5 mois, milieu de l'été).
context_page_description: In botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a single shell of hardened endocarp with a seed inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries.
  The definitive characteristic of a drupe is that the hard, "lignified" stone is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes, each individual is termed a drupelet, and may together form an aggregate fruit, although not classifying botanically as a berry. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes.
  Some flowering plants that produce drupes are coffee, jujube, mango, olive, most palms, pistachio, white sapote, cashew, and all members of the genus Prunus, including the almond, apricot, cherry, damson, nectarine, and plum.
  The term drupaceous is applied to a fruit having the structure and texture of a drupe, but which does not precisely fit the definition of a drupe.
context_section_description: In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin; and mesocarp, or flesh) surrounds a single shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside.  These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). 
  The definitive characteristic of a drupe is that the hard, "lignified" stone (or pit, as in a peach) is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit, although not classifying botanically as a berry. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes.
  Some flowering plants that produce drupes are coffee, jujube, mango, olive, most palms (including açaí, date, sabal, coconut and oil palms), pistachio, white sapote, cashew, and all members of the genus Prunus, including the almond, apricot, cherry, damson, nectarine, and plum.
