查询词典 monoecious

Generally dioecious figs have greater adaptive capacity than monoecious ones and can exist in higher seasonal environment.

Herbs, shrubs, or small trees, sometimes monoecious or dioecious.

草本，灌木，或者小乔木，有时雌雄同株或者雌雄异株。

Dioecious monoecious, reproductive structures axillary, solitary. Pollen cones pedicellate, globose, with overlapping bracts at base; microsporophylls 6-14, shield-shaped, each with 4-9 radially arranged pollen sacs. Seed-bearing structures subsessile, with several overlapping bracts basically. Ovule erected, entrusted with disc-like embryophore. After fertilization, embryophore developed into fleshy, cup-like and red aril.

雌雄异株，球花单生于叶腋，有短柄；雄球花圆球形，基部覆瓦状排列的苞片，雄蕊6-14枚，盾状，花药4-9丝，辐射状排列；雌球花几乎无柄，基部有多数覆瓦状排列的苞片，胚珠直立，基部托以圆盘状的珠托，受精后珠托发育成肉质、杯状、红色的假种皮。

Large trees, often buttressed, not epiphytic; monoecious or some species dioecious.

Recent results indicate that （1） Oryzeae is monophyletic and falls into two main clades corresponding to the traditionally recognized subtribes;（2） Close affinities of the monoecious genera are not supported, suggesting the multiple origins of unisexual florets;（3） Previous recognition of three monotypic genera （Hydrochloa, Porteresia and Prosphytochloa） is not justified;（4） Based on dating using molecular clock approach, it is estimated that Oryza and Leersia branched off from the remaining genera of Oryzeae -20 million years ago, and separated from each other -14 MYA.

目前已有的研究结果表明：稻族是单系类群，可分为两个主要分支，相当于传统的两个亚族（Zizaniinae和Oryzinae），但稻族单性花小穗是多次起源的，不宜作为划分亚族的依据；一些单型属（Hydrochloa、Porteresia和Prosphytochloa）的建立得不到分子证据的支持；根据分子钟原理估计稻族两个主要分支的分歧时间在大约2000万年前，而稻属和近缘属假稻属Leersia的分歧时间为1400万年：稻属内主要类群的分歧时间在900万年前左右。

Monoecious or dioecious. Winter bud scales many, in several whorls; outer scales imbricate, usually short and broad; inner scales longer than outer ones, ligulate to straplike.
