Architecture of paleas and lemmas dominates seed shattering trait in naked oat (Avena nuda)

Abstract Seed shattering in naked oat ( Avena nuda ) is a severe problem, resulting significant yield losses. In the present study, seed-shattering rates were characterized set of 177 cultivars and lines. Eight with different studied several morphological physiological traits that may be related to seed at developmental stages. Three types paleas, viz. boat type, defect type flaky identified dough stage, proportion boat-type paleas found positively correlate shattering. following scaling-up study on lemmas 32 rates, length, width thickness investigated, ratio bottom/medium both showed high association tolerance oat. These indicate architecture has particularly obvious correlation More intriguingly, unique zigzag pattern cell wall was lemma tissues oat, which increase toughness strength help retention.
