DENDROLOGY

Detailed explanation-1: -Axile type of placentation is seen in lemon and tomato. In this type of placentation, the ovary is partitioned into two or more chambers by septa. The placenta is formed in the central region where all the septa intersect or meet and therefore an axle column bearing ovules is formed.

Detailed explanation-2: -Definition. A type of ovule arrangement in which the ovules arise from placental tissue derived from the apices of the septa of a locule. In this type of placentation the apices of the septa are fused or in very close proximity to one another.

Detailed explanation-3: -Lemon shows axile placentation where the ovary is sectioned by radial spokes with placentas in separate locules.
