| 释义 | Definition of aril in English:arilnoun ˈarɪlˈerəlBotany An extra seed covering, typically coloured and hairy or fleshy, e.g. the red fleshy cup around a yew seed.  Example sentencesExamples  Seeds from the fruits were collected and viable seeds were distinguished by the colour of the aril (red, as opposed to dark brown for aborted seeds). The fruits, about 6 cm in length, are red or yellow, and, when ripe, split to expose three shining black seeds surrounded by fleshy arils. But the fruit's clusters of arils - or seeds surrounded by a juicy sac - are protected by sections of white, pithy membrane. What are commonly thought of as spices today are a collection of seeds, berries, flowers, fruits, kernels, roots, rhizomes, leaves, arils, barks and saps that are used in cooking and food preparation. The frail, brown shell is marked with longitudinal ridges, sometimes having a whitish aril (seed coat) fixed to one end.
 Derivatives   adjectiveBotany  The migrant bird Tersina viridis utilizes arillate seeds of the Asian tree Michelia champaca. Example sentencesExamples  It was not possible to compare the removal and predation rates between arillate and non-arillate seeds due to the fast removal of the aril by invertebrates such as harvestmen, grasshoppers and especially ants. Experimental results with another bird-dispersed tree bearing arillate seeds, Clusia criuva, have further demonstrated that ant-induced seed movements can markedly affect seedling establishment in the Atlantic rainforest. In an arillate fruit, the aril is a fleshy outgrowth of the seed's own outer covering.
Origin   Mid 18th century: from modern Latin arillus, of unknown origin; perhaps related to medieval Latin arilli 'dried grape stones'.Definition of aril in US English:arilnounˈerəlBotany An extra seed-covering, typically colored and hairy or fleshy, e.g., the red fleshy cup around a yew seed.
