作者周燕（2019）在《烯效唑对主干结果形核桃生长及果实品质的影响》一文中研究指出：本试验以温‘185’主干结果形核桃为研究材料,于2017年和2018年连续重复两年对核桃进行单株叶片喷施烯效唑处理,试验设置4个不同浓度的烯效唑,分别为150mg/L、200mg/L、250mg/L和300mg/L,以清水为对照试验。研究其对主干结果形核桃生长、光合、荧光、叶片及果实品质的影响,分析各处理间差异性,并利用主成分分析法对结果进行综合评价,以探索烯效唑使用的最佳浓度,树形构建提供科学依据,为主干形核桃的栽培、提高品质和增产提供理论依据。本试验研究主要结果如下:（1）喷施烯效唑处理后对核桃结果枝径粗和节间长均产生了一定的影响,处理均能不同程度的增加核桃结果枝径粗,缩短节间长度;其中250mg/L的烯效唑对核桃结果枝径粗增加了37.57%,150mg/L的烯效唑对节间长度的抑制效果最佳,较对照缩短了39.77%。（2）烯效唑对核桃芽和坐果率具有不同程度的影响,对枝条芽密度、芽的雌雄比和坐果率均有提高,其中200mg/L对核桃芽密度增加较明显,比对照增加了41.07%,达到显著性差异;300mg/L能提高22.73%的雌花芽与雄花芽的比值;对核桃坐果率具有提升效果,但均未表现显著性差异水平。（3）烯效唑处理均对核桃叶绿素含量和光合特性指标有不同程度的提升,核桃净光合速率（Pn）、胞间CO2浓度（Ci）、气孔导度（Gs）、蒸腾速率（Tr）和气孔限制值（Ls）均在250mg/L烯效唑处理下提升效果最佳,净光合速率提高了38.01%,蒸腾速率提高了37.05%;瞬时水分利用率在烯效唑处理浓度为200mg/L时达到最大值,较对照提高了83.38%。（4）烯效唑对核桃荧光参数Fv/Fm、Yeild、qP和ETR均有不同程度的降低,但均未达到显著性差异;在200mg/L处理下核桃qN值显著低于对照;Fo和Fm在均250mg/L烯效唑处理后达到最大值,但都未出现显著性差异。（5）烯效唑对核桃叶片解刨结构各指标均有不同程度的影响,250mg/L核桃上表皮和下表皮厚度提升效果最佳,200mg/L对栅栏组织厚度增加最明显,较对照提高了16.50%,海绵组织在300mg/L处理下增加效果最佳,较对照试验提高了67.50%;烯效唑处理具有抑制气孔发育的作用,导致气孔密度降低,在250mg/L处理对气孔密度抑制达到最大。150mg/L能显著增大核桃叶片的干物质比,提高了17.39%;200mg/L处理对叶片细胞结构紧密度提升效果最佳,较对照提高了38.29%;300mg/L处理下核桃叶片叶面积和细胞结构松弛度达到最大值。（6）烯效唑对核桃叶片碳、氮相关代谢酶具有不同程度的提高效果,300mg/L烯效唑处理对硝酸还原酶活性提升了41.73%;250mg/L烯效唑除处理对蔗糖合成酶和谷氨酸脱氢酶活性提升最大,分别提高了61.65%和81.89%;200mg/L烯效唑对蔗糖磷酸合成酶活性提升提高了58.73%。（7）烯效唑对核桃果实三径（横径、纵径、侧径）和果形指数的影响均未达到显著差异,300mg/L烯效唑处理对核桃果实缝合线紧密度提升效果最佳,提高了53.95%,极显著高对照;200mg/L处理均对核桃果实单果重、仁重和出仁率的增加效果最佳,出仁率提高了11.07%;250 mg/L处理能够极显著的增加核桃单位产量,单位产量提高了14.61%。250mg/L烯效唑对果实可溶性总糖和还原糖含量提升效果最佳,150mg/L能够显著降低纤维素含量;200mg/L处理后蛋白质含量提升了10.07%,250mg/L处理后脂肪含量提升效果最好,提高了5.05%,还降了低单宁含量,但均未达到显著性差异;300mg/L对碘价含量提升效果最佳。
