Changes in soluble carbohydrates in yellow lupin seed under prolonged storage
Yellow lupin seeds (Lupinus luteus L. cv. Juno) were stored for 10 years. Their vigour, viability as well as the content and composition of soluble carbohydrates (raffinose family oligosaccharides, galactosyl cyclitols and cyclitols) were investigated in yellow lupin seeds. The dominant soluble carbohydrates were sucrose and raffinose family oligosaccharides, with stachyose being the most abundant. Oligosaccharides levels ranged from 16% (in seeds stored for ten years) to 73% of the total soluble sugars (seeds stored for one year), sucrose content was 52% of the total soluble sugars in seeds stored for ten years and 18% stored for one year. The initial longevity and vigour of the seeds were the main parameters considered in long-term seed storage.
