Abstract
Abstract Changes in soluble sugars in cauliflower seeds were followed during 50 h of imbibition in relation to desiccation tolerance. Sucrose and stachyose contents decreased, and glucose and fructose accumulated. This occurred in radicles first and subsequently in hypocotyls and cotyledons. Loss of desiccation tolerance in the various seed parts coincided with an increase in glucose and fructose and the complete loss of stachyose, but sucrose content, the major sugar, was still high. Drying imbibed seeds over silica gel did not evoke resynthesis of stachyose, but did increase sucrose and decrease glucose and fructose contents. Seeds primed in solutions of 30% polyethylene glycol for 10 days showed a loss of stachyose, while sucrose remained high and glucose and fructose contents were still very low. Redrying of primed seeds did not change the sugar contents. The primed seeds were still tolerant of desiccation. We conclude that stachyose is not a prerequisite for desiccation tolerance, but that sucrose may be. We suggest that glucose and fructose may be involved in desiccation damage.
