[R] Apium graveolens L. (Apiaceae).
Fr: Céleri; Ge: Knollensellerie; Sp: Apio; It: Sedano; Pt: Aipo.
- Biennial plant with small white, yellow or greenish flowers arranged in an umbel (*) . It may be found in the wild state in salt marshes around the Mediterranean Sea.
- France is the principal European producer.
- Several varieties are distinguished: turnip-rooted celery (A. g. rapaceum Millière), whose root is fleshy and is consumed raw or cooked; branched celery (A. g. secalinum),where the well developed leaves and petioles are consumed; and little celery (A. g. secalinum), cut and used as seasoning.
- It is sown in spring and transplanted when there are 2 or 3 leaves. It is often tied. Harvesting is spread out.
- Diseases: the most serious diseases are those caused by septoria, present in all regions, and phoma diseases, whose damage to turnip-rooted celery occurs essentially in the north.
- Principal European pests: the most serious pests are the carrot fly (Psila rosae) and the (Philophylla heraclei) which damage the roots and the leaves.
The stem nematode (Ditylenchus dipsaci) and the two-spotted spider mite (Tetranychus urticae) cause deformation and discoloration of the leaves; Liriomyza strigata (Dip., Agromyzidae), and the American serpentine leaf miner (L. trifolii) form tunnels between the two epidermal layers in the leaves.
Root-knot nematodes (Meloidogyne ) cause the formation of galls on the root system.
