Comparative studies on growth and physiological reaction of thellungiella salsuginea under nacl and na2so4 stresses 4对盐芥生长和生理胁迫效应的比较
Physiological reactions of cultured cymbidium goeringii to different temperatures and concentrations of cytokinin 不同温度和激素浓度对春兰部分生理活动的影响
Exactly why humor causes this acoustic response - - rather than , sya , sweaty palms or any other physiological reaction - - has been lost in the mists of evolution 幽默为什么会引起这种声学反应,而不是手心出汗或其他什么生理反应,其确切原因在茫茫的进化,过程中迷失了。
In most plants this is achieved by physical barriers preventing entry of pathogens and by physiological reactions to isolate the pathogen and its effects 在大多数植物中,免疫过程就是个体以自然屏障为防御病原体的中心,然后进行生理性的隔离,使病原体的破坏作用被阻断。
The injury is abnormal , but the body ' s reaction , inflammation , is a normal , if complex , physiological reaction , the only one possible in the circumstances of that particular injury 损伤是异常的,而机体的炎症反应却是正常的,即使炎症反应过程十分复杂,在此情形下,导致该生理反应发生的唯一可能也应为损伤所致。
It was important glucoprotein modulating cell functions by combination to idiosyncrasy receptor on cell membrane , which inducing process of cascade signal magnifying , then passing signals into nucleus to induce the modulation of the serial gene expression and viarous physiological reaction , and inhence immunity and antivirus 人-干扰素( hu - - ifn )是人体因病毒感染或其它诱生剂作用等所产生的一类非特异性抗病毒物质,是调节细胞功能的一类重要的糖蛋白。
The physiological reactions vii to hypoxia are most severe in the fulminating altitude hypoxia group , such as tempestuously struggling , twitching , weakly breathing , dull sight , stopping breath in 2 ~ 7min . sinus arrhythmia , nodal arrhythmia , ventricular premature beats and ventricular escape beats can be observed in the fulminating altitude hypoxia group , stopping beat at last . 2 该组大鼠在暴发性缺氧期间出现剧烈挣扎,抽搐,呼吸浅快,目光呆滞以及毛发棘立等行为改变,于2 7min呼吸停止;出现了不同程度的窦性心律不齐、结性心律、室性早搏、室性逸搏等心电图改变,继之出现心率减慢,直至心脏停跳。
This review focuses on morphological and physiological reactions of fruit tree to water stress . leaf area , root growth and microstructure of leaves and roots were investigated . some physiological and biochemical index of fruit tree leaves and roots under water stress , such as variations of stomatal aperture , photosynthesis , photoinhibition , metabolism of lipoxygenase , content of proline , nuclear acid and endogenous phytohormones , were summarized 从水分胁迫对果树叶、根的形态指标及显微结构,叶片气孔行为、光合作用、光抑制、活性氧代谢、脂氧合酶代谢、多胺代谢、脯氨酸、核酸代谢、内源激素变化等生理生化方面综述了近十几年来的研究成果,为全面研究果树抗旱机理及进一步制定抗旱措施奠定理论基础。
The physiological reaction of c . junos under iron stress in field experiments , c . junos manifested itself as tolerant to iron stress . no chlorosis symptom was not found in its leaves when it was grown in a soil with ph 7 . 8 . in contrast , severe chlorosis was found in the control plant p . trifoliata grown under the same soil conditions , and leaf chlorophyll content as an indicator for the degree of fe deficiency in p . trifoliata was much lower than in c . junos 主要的研究结果如下: 1 :铁胁迫下香橙的生理反应研究香橙在田间实验中表现耐缺铁,在ph7 . 8的土壤中生长正常,叶片无任何缺铁症状;但对照植物枳在同样土壤条件下却表现出明显的缺铁症状,作为缺铁程度指标的叶片叶绿素含量极显著低于香橙。
