雌雄同株

Inflorescences in axillary pairs or solitary, cymes, panicles or spikes, unisexual; male inflorescence often long, flowers clustered on rachis of spikes, dichotomous cymes, or panicles; female glomerules lax or dense on rachis of scorpioid cymes, spikes, or panicles.

花序在腋生成对或单生，聚伞花序，圆锥花序或穗状花序，单性（植株雌雄同株或异株；雄花序通常长，在穗状花序，二歧的聚伞花序，或圆锥花序的轴上的花簇生；雌性团伞花序在蝎尾状聚伞花序、穗状花序或圆锥花序的轴上疏松或紧密。

Herbs perennial, long stoloniferous, glabrous, dioecious or monoecious.

多年生草本，长，无毛，雌雄异株或者雌雄同株。

Inflorescences solitary, axillary, often pedunculate, seated on a receptacle; receptacles at first broadly subcampanulate, soon expanded, of unisexual flowers; male and female inflorescences often separate or sometimes mixed in same receptacle, rarely male ones capitate or cymose without receptacle; involucral bracts in 1 or 2 whorled rows along margin of receptacle.

花序单生，腋生，通常有花序梗，在一花托上坐下；花托最初宽近钟状，不久膨大，单性花（植株雌雄同株或异株；雄和雌花序通常有时分开或在相同花托内混合，很少的雄性头状或没有花托；花托的总苞片1或2轮排在边缘。

Trees or shrubs, deciduous, with latex; monoecious or dioecious. Winter buds with 3-6 bud scales; scales imbricate. Stipules free, sublateral, caducous.

乔木或灌木，落叶，具乳汁；雌雄同株或异株冬芽具3-6芽鳞；鳞片覆瓦状托叶离生，近侧生，早落。

The ethylene release rate was measured in shoot tip of different sex ramie in different time, the budof same node in female and hermaphrodite ramie in second crops and different sex singleinflorescence in hermaphrodite ramie. The result indicated there was closed relationship betweensexual different ramie and ethylene release rate. The female ramie could be induced by highethylene release rate. the ethylene content in ramie plant with female flower is higher than ramieplant with androgynary in stem apex, leaf and flower.

5对不同性别苎麻茎尖乙烯释放速率、不同性别苎麻材料不同节位花芽乙烯释放速率、雌雄同株苎麻的雌花序、雄花序和雌雄混合花序的乙烯释放速率进行测定，同时对外施乙烯抑制剂(AVG和AgNO_3)对苎麻性别的控制进行研究，表明苎麻性别分化与内源乙烯密切相关，高水平乙烯释放速率诱导雌株苎麻或雌花的产生。

According to cytology, biology, oil chemical characteristic and castor-oil plant's physical and chemical properties, it surveys both domestic and international research on the progress and development of castor-oil plant hereditary improvement, hybrid vigour utilization and comprehensive utilization.

研究立足于蓖麻遗传多样性及其植物质能的综合利用潜势，根据蓖麻雌雄同株的细胞学、生物学和油脂化学特性和毒蛋白的物化性质，综述国内外有关蓖麻生物学、遗传育种、杂种优势及综合利用的进展与研发前景。

Inflorescences axillary, glomerules forming spikes or panicles of unisexual flowers (plants dioecious or rarely monoecious); bracts small.

花序腋生，团伞花序形成穗状花序或圆锥花序单性花植株雌雄异株或很少雌雄同株；苞片小。

Inflorescences axillary, sessile, glomerules of unisexual flowers; male glomerules distal; female ones proximal, or sometimes mixed in middle.

花序腋生，无柄，单性花（植雌雄同株或异株；雄性团伞花序上部；雌性的下部，或者有时混合在中部。

Erect shrubs or small trees, dioecious, rarely monoecious; branchlets sometimes spine-tipped, indumentum of simple hairs, often absent.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
