香菇Lentinula edodes质地是影响其食味品质和货架期的一系列重要品质指标。本研究首次基于质构仪质地多面分析法（TPA）,结合传统感官评级对ZX6（浙香6号）和Lsm9两个香菇亲本及其2个杂交菌株（L1*11和L4*6）子实体的不同部位（菌柄P1、菌盖顶部P2、菌盖中心P3和菌盖侧边P4）的7个质地指标和2个传统的感官评级（菌盖紧实度和菌柄紧实度）进行评价。相关性分析显示传统感官紧实度评级可以与6个质地指标存在显著相关性,说明TPA方法可取代并量化传统方法,不同取样部位的相关性分析显示菌盖中心取样部位（P2）在7个参数中与其他菌盖部位具有最大范围的相关性,这与主成分分析结果基本一致,说明P2可最大程度代表菌盖的质地情况。此外,显著正相关存在于硬度1、粘附性、硬度2、弹性、胶黏性和咀嚼性6个指数间。从品种和遗传角度而言,ZX6除了内聚性较低以外,其他参数均高于Lsm9。杂交菌株L4*6在硬度1、硬度2、弹性、胶黏性和咀嚼性5个指数与低值亲本Lsm9无显著差异,说明Lsm9决定上述指标的遗传变异在杂交F1菌株L4*6存在一定程度的显性遗传,L1*11在硬度1、硬度2和胶黏性方面显著低于双亲,存在“超亲现象”。本研究为后续香菇子实体质构分析提供了科学和精细的方法依据,同时也为遗传学分析提供基础。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});//可视化图谱$(document).ready(function(){if($("#showArticle_knowledgeMap") && $("#showArticle_knowledgeMap").length && $("#showArticle_knowledgeMap").length>0){jQuery.getJSON("/Jwxb/CN/lexeme/existsCnctstInArticle.do?articleID="+$("#articleId").val(), null, function(json){if(json.result){$("#showArticle_knowledgeMap").show();}});}});$(document).ready(function(){var metaDataStr = $.trim($("#article_metaJson").val());if(metaDataStr!=''){eval("window.metaData="+metaDataStr);}if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
