摘  要:
可可是世界三大饮料作物之一,可可种子为顽拗性种子,含水量低于某一相对高的临界含水量时,其种子就会丧失活力。为探讨可可种子的贮藏方法,研究分析了果实处理方法、温度、时间对可可种子发芽及幼苗生长的影响。结果表明:可可种子经过4℃处理后便丧失了发芽力,室温25℃条件下果壳不破开,放置30 d后可可种子仍有近50%的发芽率;清洗可可种子果肉后短时间放置,可以提升种子的发芽势,并且能促进幼苗前期生长。

摘  要:
Cocoa is one of the three biggest worldwide beverage crops. Cocoa seeds are recalcitrant,which have to maintain high water content to keep their vitality. In order to investigate storage method of cocoa seeds, we analyze various treatments on seeds germination and seedling growth, including the fruit treatment, temperature and time. Our results indicated that cacao seeds lost germination ability after 4℃treatment, almost 50% treatment seeds could germinate when placed 30 days with unbroken pod husk in room temperature 25℃. In the short phase, cleaning cacao seed pulp could enhance the germination potential and promote early seedling growth.
