Protein Complex as Indicator of Seed Recalcitrance | Biomedgrid llc

Late stage of seed ripening and storage compounds accumulation is accompanied with maturation drying, seeds become desiccation tolerant, and may survive for a long time in the dry state. These seeds are named orthodox. However, part of species, especially originated from tropics, produces so-called recalcitrant seeds. Recalcitrant seeds do not dry at the end of maturation, they have high moisture content and active metabolism; recalcitrant seeds remain desiccation sensitive. Seed recalcitrance is often found in moist, warm climatic zones, without seasonal changing [1,2]. In tropical rainforests seed recalcitrance and fast germination of moist seeds gives preference to a species [3]. But recalcitrant seeds are not storable for a long time, and it is a problem for agriculture. Predicting of seed storage behavior is very important for seed preservation, seed banks, for developing an ex-situ conservation strategy. Different tests have been developed for estimation of seed desiccation tolerance or sensitivity
