Effects of enhanced ultraviolet - b radiation on soluble protein and nucleic acid in rice leaves 辐射增强对水稻蛋白质及核酸的影响研究
Effects of enhanced ultraviolet - b radiation on diurnal changes of photosynthesis and water use efficiency in luffa cylindrica 辐射对丝瓜光合作用日变化及水分利用效率的影响
1 ) under the enhanced ultraviolet - b radiation , the wheat seedlings shown the decreased height and leaf area , accumulation of screening pigments and " root - bending " 结果表明: ( 1 )经增强uv - b辐射后,小麦明显表现出植株矮化、叶片卷曲、颜色加深,并产生“翘根” (胚根向上弯曲)现象。
Under the condition of the enhanced ultraviolet - b radiation , the phenomenon of abnormal mitosis was first discovered , such as the three - bundle > four - bundle and six - bundle division of the chromosome when the cell is in anaphase 并在uv - b诱导的小麦根尖细胞中,首次发现染色体在有丝分裂的后期到末期,分成3束、 4束和6束等异常分裂新类型。
