Abstract
Cottonseed exposed to a temperature of 5[degree] during hydration are killed, or the subsequent germination performance of surviving seed is seriously inhibited. Exposure to chilling for periods as short as 30 min. reduces germination speed and induces root abnormalities, while chilling for 12 hr. may kill all seed. Sensitivity to chilling persists during the initial 2 -4 hr. of hydration. Seeds imbibed 4 hr. at 31 [degree], then dried, retain immunity to chilling. An irreversible event that is blocked or disrupted by chilling apparently occurs during early seed hydration.This publication has 6 references indexed in Scilit:
