Development in Michelia Champaca
Pollination
Fertilization and Embryo development
Ovary develops into fruit and ovule develops into seed
Fruits dispersed and seeds grow in a suitable condition
Similarity
A large evergreen tree when grow in forest Usually small tree (6m) we can find
around us Known for its strongly fragrant flower Contain many kind of volatile oil in its
flower Perfect but incomplete flower (no sepals) Dicot plant
Netlike vein Floral part in multiples of 5
Differences
Light yellow when young, turning dark orange in maturity.
Zygomorphic simple flower (bilateral symmetry)
Remain white in young and maturity.

Fruit
1. Fruiting (follicles) is free. 2. Basally united to the axis or
shortly stalked. 3. 3-20 laxly that are arranged in a
6-9 cm long cluster. 4. Fruit is flat tened ovoid to slightly
spherical size 1.5-3.5 cm x 1-2.5 cm.
5. Partially woody, pale brown with white warts con taining 2-6 seeds.
6. Their fruits are about 30 in a cluster, each with a 3 mm long and densely hairy stalk.
7. The fruiting spike is compact.
Types of Fruits
Fruits are classified according to the arrangement from which they derive.
Michelia champaca is aggregate fruit. Each carpel develops into fleshy globule
that contains one of several seeds. Collection of follicles developing from one
flower
Seed
Seed is ovoid and red-brown and in open fruit it is hanging on little thin cord that is attached to the placenta.
The seeds are brown with a pinkish fleshy aril. The seeds, 1-2 is brown when old ,polished
and various angled. The plant doesn't require pruning and has
naturally full and bushy shape. Seedlings start to bloom within 2-3 years
