The Effects of High-temperature Stress on the Component of the Phloem Exudates of Flag Leaf and Peduncle of Winter Wheat

doi:10.3321/j.issn:1000-7091.2003.03.004

Abstract

Abstract: This study, focus on the component changes of phloem exudates from peduncle and flag leaf of winter wheat under high-temperature stress. The result showed that the high-temperature stress can decrease the content of solubility sugar in the phloem exudates from peduncle and flag leaf, decrease the amino acid content in the phloem exudates from peduncle while increase it in the phloem exudates from the flag leaf. The component of amino acid in the phloem exudates from peduncle and flag leaf also have significantly changes.

Key words: High-temperature stress, Flag leaf, Peduncle, Phloem exudates, Amino acid
