Part I.—POLLINATION STUDIES OF SEED PRODUCTION.
Part II.—STRUCTURE AND CHEMICAL NATURE OF THE SEED COAT AND ITS RELATION TO IMPERMEABLE SEEDS OF SWEET CLOVER.
LITERATURE CITED.
The first section dives into the puzzling shortage of sweet‑clover seed despite abundant flowering. Researchers track every step from flower anatomy to pollen germination, testing how timing, weather, and moisture affect fertilization. By observing insects in the field and manipulating blossoms, they uncover which pollinators boost yields and which conditions hinder pod development.
The second part shifts to the seed’s protective coat, probing its microscopic structure and chemical makeup. Detailed lab work compares permeable and impermeable coats, revealing how water absorption—or the lack of it—governs germination potential. The study also experiments with acid treatments, offering practical insights for improving seed viability without revealing the final outcomes.
