The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of cucurbit physiology and bitterness.
Step 2: Detailed Explanation:
The bitter principles in cucurbits (cucurbitacins) are due to the phenomenon called Metaxis.
Metaxis is a phenomenon where:
- One part of a plant shows different characteristics from another.
- It is a type of somatic mutation.
- In cucurbits, it leads to bitterness due to cucurbitacin synthesis.
Other terms:
- Luxriance (A): Not a standard horticultural term.
- Metaxania (B): Not a standard term.
- Metalaxis (D): Not a standard term.
Cucurbitacins are:
- Triterpenoid compounds.
- Responsible for bitterness.
- Toxic in high concentrations.
- Protect plants from herbivores.
Thus, metaxis is the phenomenon causing bitterness in cucurbits.
Step 3: Final Answer:
Thus, the bitter principles of cucurbits is due to the phenomenon metaxis, which corresponds to option (C).
