Which of the following is shade demander species in tropical deciduous forest?
Show Hint
Kusum (Schleichera oleosa) requires overhead protection (shade) in its early sapling stages to survive, making it a prominent shade demander in dry mixed deciduous forests.

- Schleichera oleosa
- Gmelina arborea
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Fishes and forest tree species are classified based on their tolerance to light during different stages of their life cycles into light demanders, shade bearers, and shade demanders.
Step 2: Detailed Explanation:
- Dalbergia sissoo (Sissoo) is a pioneer species and a strong light demander; it cannot grow under a dense canopy.
- Gmelina arborea (Gamhar) is also a strong light demander requiring full sunlight for optimal growth.
- Dalbergia latifolia (Rosewood) is a moderate light demander to shade bearer.
- Schleichera oleosa (Kusum) is a classic shade-demanding species in its youth. Young seedlings and saplings grow best under the canopy shade of existing deciduous forests, which protects them from dry, scorching solar radiation and moisture stress.
Step 3: Final Answer:
Schleichera oleosa is classified as a shade-demanding species in tropical deciduous forests.
