The hardwood is produced by which of the following trees?
Hardwood vs. Softwood: A Botanical Distinction
In botany and woodworking, timber is classified into two main categories: hardwood and softwood. This classification is based on the tree's botanical reproduction, not its actual hardness or softness.
- Hardwoods come from deciduous trees—those that have broad leaves and typically lose them in the winter (e.g., Oak, Teak, Shisham).
- Softwoods come from coniferous trees (gymnosperms)—those that have needles and cones and are typically evergreen (e.g., Pine, Fir, Deodar).
📝 Detailed Analysis of the Options
(a) Chir, (b) Kail, and (c) Pine
These are all types of coniferous trees. Chir and Kail are species of Pine trees found in the Himalayas. As conifers, they all produce softwood. Softwoods are generally lighter, less dense, and less expensive than hardwoods, commonly used for general construction, paper pulp, and millwork.
(d) Shishum
This is the correct answer. Shisham (also known as Sheesham or Indian Rosewood) is a deciduous tree, and therefore it produces hardwood. Shisham wood is known for being very hard, heavy, and durable with a distinct grain. Its properties make it highly valued for high-quality furniture, cabinetry, and decorative items. It has a high compressive strength (around 90 kg/cm²) and density (around 800 kg/m³ at 12% moisture).
📊 Hardwood vs. Softwood at a Glance
| Feature | Hardwood | Softwood |
|---|---|---|
| Source Tree | Deciduous (broad-leaved) | Coniferous (needle-leaved) |
| Examples | Shisham, Teak, Oak, Sal | Pine, Chir, Kail, Deodar, Fir |
| General Density | Higher | Lower |
| Common Uses | High-quality furniture, flooring, heavy construction | General construction, doors, windows, paper |
💡 Study Tips
- Hardwood = Broadleaf: Remember that hardwoods come from trees with broad leaves that they usually shed in winter.
- Softwood = Needles & Cones: Softwoods come from evergreen trees with needles and cones, like Christmas trees.
- Know Your Local Trees: Familiarize yourself with common Indian timbers. Shisham, Sal, and Teak are classic examples of hardwoods, while Deodar, Pine, Chir, and Kail are common softwoods.
