The role of seed coats in seed viability.

From: The Botanical Review | Date: October 1, 1994| Author: | Copyright information

The seed coat is the seed's primary defense against adverse environmental conditions. A hard seed coat protects the seed not only from mechanical stress but also from microorganism invasion and from temperature and humidity fluctuations during storage. Phenolic compounds in the seed coat contribute to seed hardness and inhibition of microorganism growth. During germination, the seed coat protects the seed from hydration stress and electrolyte leakage.

II. Introduction

Seeds are fundamentally important to people, not only because they constitute the chief method of plant propagation, but ...
