研究了干旱胁迫条件下,凤尾竹、孝顺竹、四季竹等3种观赏竹叶片的游离脯氨酸含量、可溶性糖含量,超氧岐化酶(SOD)以及过氧化氢酶(CAT)的活性变化。结果表明:随着干旱胁迫时间的延长,3个竹种叶片脯氨酸含量呈增加趋势,叶片可溶性糖含量呈先升后降趋势,而叶片超氧岐化酶( SOD)以及过氧化氢酶( CAT)活性总体上均呈下降趋势。根据4项生理指标,采用模糊隶属函数法对其抗旱性进行综合评价,抗旱能力强弱顺序为:四季竹>凤尾竹>孝顺竹。
研究瞭榦旱脅迫條件下,鳳尾竹、孝順竹、四季竹等3種觀賞竹葉片的遊離脯氨痠含量、可溶性糖含量,超氧岐化酶(SOD)以及過氧化氫酶(CAT)的活性變化。結果錶明:隨著榦旱脅迫時間的延長,3箇竹種葉片脯氨痠含量呈增加趨勢,葉片可溶性糖含量呈先升後降趨勢,而葉片超氧岐化酶( SOD)以及過氧化氫酶( CAT)活性總體上均呈下降趨勢。根據4項生理指標,採用模糊隸屬函數法對其抗旱性進行綜閤評價,抗旱能力彊弱順序為:四季竹>鳳尾竹>孝順竹。
연구료간한협박조건하,봉미죽、효순죽、사계죽등3충관상죽협편적유리포안산함량、가용성당함량,초양기화매(SOD)이급과양화경매(CAT)적활성변화。결과표명:수착간한협박시간적연장,3개죽충협편포안산함량정증가추세,협편가용성당함량정선승후강추세,이협편초양기화매( SOD)이급과양화경매( CAT)활성총체상균정하강추세。근거4항생리지표,채용모호대속함수법대기항한성진행종합평개,항한능력강약순서위:사계죽>봉미죽>효순죽。
The contents of free proline , soluble sugar and SOD activity , CAT activity of three bamboo leaves ( B.multiplex cv.Fernleaf,B.multiplex (Lour.) Raeuschelex J,S.tootsik (Sieb.) Makino ) were studied under natural drought stress condi-tions.The results showed that free proline contents of bamboo leaves increased ,the soluble sugar content increased at first and then decreased ,SOD activity and CAT activity decreased with the prolongation of the stress time.The method of obscure mathematics was used to evaluate their drought resistance ability comprehensively based on physiological and biochemical indexes .The ability of drought resistance indicated that S.tootsik ( Sieb.) Makino>B.multiplex cv.Fernleaf>B.multiplex ( Lour.) Raeuschelex J accord-ing to the results of fuzzy administering function.
