    Pneumatic Method to Measure Plant Xylem Embolism
    气动法检测植物木质部栓塞
    作者:  Paulo R. L. Bittencourt, Luciano PereiraRafael S. Oliveira, 日期: 10/20/2018, 浏览量: 5578, Q&A: 0
    Embolism, the formation of air bubbles in the plant water transport system, has a major impact on plant water relations. Embolism formation in the water transport system of plants disrupts plant water transport capacity, impairing plant functioning ...
    Protocol to Test the Effect of Sorbitol in vitro on Hybrid Larch (Larix x eurolepis Henry) Emblings
    体外检测山梨醇对杂种落叶松(Larix x eurolepis Henry)胚形成的实验方案
    作者:  Bettina JohstMaría del Carmen Dacasa Rüdinger, 日期: 07/20/2018, 浏览量: 4226, Q&A: 0
    This protocol presents a method to test the effect of sorbitol in vitro on hybrid larch plants derived from somatic embryogenesis. We have tested four different media variants, one control variant without sorbitol and three variants of ...

    使用DMSO增加膜蕨类的膜通透性
    作者:  Marcelo Garcés, 日期: 06/20/2018, 浏览量: 4255, Q&A: 0
    Cell membrane prevents the entrance of extra molecules (e.g., transcription and translation inhibitors) into the cell. For studying the physiological effects of transcription and translation inhibitors on Hymenophyllum caudiculatum ...
    Slow and Fast Desiccation of Single-cell Thick Fronds of Filmy Ferns
    膜蕨类植物单细胞厚叶状体的缓慢及快速干燥
    作者:  Marcelo Garcés, 日期: 06/05/2018, 浏览量: 4440, Q&A: 0
    Filmy ferns can desiccate and recover after rehydration to resume photosynthesis. Slow and fast desiccation rates were compared in filmy fern fronds to determine whether structural or physiological differences may occur between desiccation rates. ...
    水稻组织脯氨酸含量的测定
    Measurment of Proline Content in Rice Tissue
    作者:  都浩, 游均熊立仲, 日期: 04/27/2018, 浏览量: 3354, Q&A: 0
    实验原理:水稻在非生物逆境条件下,体内脯氨酸(proline)含量显著增加。可用磺基水杨酸提取水稻组织中脯氨酸,然后用酸性茚三酮加热处理后,溶液即成红色,再用甲苯萃取使色素全部转移至萃取液中。色素的深浅即表示脯氨酸含量的高低。在520 ...
    水稻叶片中丙二醛(MDA)含量的测定
    Determination of Malondialdehyde (MDA) Content in Rice Leaves
    作者:  都浩, 王妮丽熊立仲, 日期: 04/27/2018, 浏览量: 5941, Q&A: 0
    实验原理:水稻器官衰老或在非生物逆境条件下,膜脂发生过氧化作用,丙二醛(malondialdehyde)是其产物之一,通常利用它作为膜脂过氧化指标。MDA在高温及酸性条件下与TBA反应形成有色物,在532 nm波长处有最大吸收值,600 nm波长处有最小吸收值。 ...
    水稻叶片相对含水量测定
    Determination of Relative Rice Leaf Water Content
    作者:  都浩, 郭子龙熊立仲, 日期: 04/27/2018, 浏览量: 5775, Q&A: 0
    实验原理:水稻叶片在非生物逆境胁迫条件下,叶片含水量有着较大的差异。
    实验目的:通过叶片相对含水量的不同,检测水稻在非生物逆境下保持水分的能力,相对含水量越高,则水稻抗失水能力越强。
