The study was an overview by nature and provided only a partial idea of the system of changes of the reproductive system in ewes without taking into account the complex relations between morphology and the function of the reproductive organs 该研究只是通过自然观察而没有考虑生殖器官形态和功能的复杂关系，所以只是对母羊生殖系统变化规律的部分观点。
Male patients will have thick copious purulent milk - like urethral discharge . without effective treatment , the infection may gradually spread to the reproductive organs and cause constriction of the urethra , making urination difficult 小便频密、刺痛；尿道口排出混浊的白色脓液；若不加医治，病菌会蔓延到整个男性生殖器官，做成尿道狭窄，小便困难。
Abstract : leptin , the product of obese gene , may control the development of animals ' puberty , reproductive organs and functions , by acting on hypothalamus or on ovary directly . this paper summarized the mechanisms and effects of leptin on reproduction 摘要肥胖基因的产物- -瘦蛋白可通过下丘脑或直接作用于卵巢,对动物的青春期发育、生殖器官的发育以及性激素的分泌都有重要的调节作用.本文拟对瘦蛋白的作用机制及其对繁殖性能的影响作一综述。
The differentiation of the studied morphological characters shows that the differentiation of vegetative organs is greater than that of reproductive organs and the differentiation of reproductive organs does n ' t reach the notable level , which indicates that the morphological differentiation mainly occurred in the vegetative organs and is caused mainly by environment factors 在所研究的形态性状中，其差异程度表现出：营养器官的变异大于生殖器官的变异，所测量的生殖器官性状的变异均没达到显著水平，这说明形态分化主要表现在营养器官特征上，也说明营养器官受环境影响较大。
7 ) after analyzing the relationship among biomass above ground , height and basal diameter of reed , the regression equation model can be concluded as : w = 7 . 03845 ( d2h ) 0 . 905385 . at the same time , some other models can be got also , such as the seasonal dynamics model of biomass above ground and biomass under ground , the partitioning model of biomass above ground 7 )通过分析得出了芦苇地上生物量与株高和基径间的回归方程模型w一7 . 03845 ( dzh ) ” 05 ， 8 ， 、芦苇地上和地下生物量的季节动态模型、地上生物量在营养器官和生殖器官间的分配模型。
Meanwhile , morphological characteristics of d . glomerata have significant relationships : those with upright and constrictive inflorescences have longer and narrower leaves , stronger stems , longer flag leaves , well - developed stamens and stronger seed reproductive capacity , whereas those with pendulous inflorescence have the opposite characteristics 2 )鸭茅植物形态学特征间存在明显相关性，花序直立、紧缩的鸭茅，叶片窄长，茎秆粗壮，旗叶较长，雄性生殖器官发育良好，结种性能强；而花序下垂、开展的鸭茅则与之相反。
Beyond that , in order to explain why women mother , they tend to rely on vague notions of a girl ' s subsequent identification with her mother , which makes her and not her brother a primary parent , or on an unspecified and uninvestigated innate femaleness in girls , or on logical leaps from lacation or early vaginal sensations to caretaking abilities and commitments 除此之外，为了解释女人何以为母亲，他们基于这样一种模糊的认识，认为女孩紧接其母亲的认同，使她而不是她的兄弟成为原初的母亲；或认为女孩具有不被知晓的天生的女性特质；或从哺乳或生殖器官的感受到照顾的权力义务之间进行逻辑关联。
Therefore , after tasseling whether the nutrient supply is adequate or not will greatly influence the formation of grains , especially for the high - yielding cultivars of which the amounts of accumulative dry matter in reproductive organ account for a wide proportion of the total amount , so it is very important to apply adequate amount of fertilizers in earring stage 因此，抽雄后养分供应是否充足将极大影响籽粒形成，特别是高产品种，生殖器官中干物质积累量占总积累量的很大部分，所以抽雄期充足施肥至关重要。
