nutrient remobilization efficiency
noun phrasePronunciation: /ˈnuːtriənt ˌriːmoʊbɪləˈzeɪʃən ɪˈfɪʃənsi/
The proportion of nutrient elements relocated from senescing leaves and other organs to reproductive structures or storage tissues before senescence-driven organ abscission. High remobilization efficiency enables plants to maintain productivity under nutrient-limited stress conditions.
Plain English
How effectively plants recycle nutrients from old leaves to seeds and growing parts during nutrient stress.
Etymology & History
Usage
"Legume crops show higher nitrogen remobilization efficiency than cereals, allowing grain filling despite limited soil nitrogen availability."
Style guide notes: Express as percentage values and specify which nutrient element and source/destination organs are measured.

Frequently Asked Questions
Why is nutrient remobilization important under deficiency stress?
It reduces dependence on soil nutrient availability, allowing continued grain/seed production when root uptake is limited by stress.
Which nutrients are most efficiently remobilized in plants?
Nitrogen and phosphorus are typically remobilized at 50-80% rates, while calcium and silicon show lower remobilization percentages.
Why Test Candidates on This?
Important for understanding crop performance under nutrient-limited conditions and breeding for resource-use efficiency.
