Nutrient Remobilization Capacity
nounPronunciation: /ˈnjuːtriənt ˌriːmoʊbɪləˈzeɪʃən kəˈpæsɪti/
The physiological efficiency with which plants relocate essential nutrients from mature or senescent tissues to developing organs during periods of nutrient limitation or stress. This process involves degradation of proteins and compartmentalization changes to maximize nutrient availability for critical growth functions.
Plain English
The plant's ability to move nutrients from old tissues to new growth when nutrient availability is limited.
Etymology & History
Usage
"High nutrient remobilization capacity enables crop varieties to maintain grain filling despite soil nutrient depletion."
Style guide notes: Specify which nutrients are being remobilized and which tissues serve as source and sink in detailed analyses.

Frequently Asked Questions
How do plants remobilize nutrients during stress?
By breaking down proteins in mature leaves and translocating released nutrients through phloem to developing tissues.
Why is remobilization important in agriculture?
It allows crops to maintain productivity and seed filling despite limited soil nutrient availability, reducing fertilizer dependence.
Why Test Candidates on This?
Essential for crop improvement programs focusing on nutrient-use efficiency and stress resilience under limited input conditions.
