Abstract

fetched live from OpenAlex

This chapter focuses on the physiological processes of vegetables that determine changes in both perceptible quality and nutrient and functional constituents. The storage potential of vegetables depends upon their structure, developmental stage, the respiration rate at harvest and the subsequent physiology. There are essentially three subgroups of vegetables, with different postharvest physiologies and therefore storage requirements: leaves, stems, flower buds and inflorescences; fruit-vegetables; and biennial vegetables. The chapter tabulates the differing vegetable types and their respiratory characteristics. Beyond basal metabolism (respiration), there are other unique physiological characteristics of specific vegetables that result in differing considerations in postharvest handling. The chapter also discusses all these considerations. Phytohormones are a fundamental component of plant growth and development. Bulb vegetables such as onion show differing patterns of change for all the major classes of phytohormones. Ethylene has been the most studied phytohormone in fruit ripening.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
