的沉著在葉柄和莖尖數(shù)量的增加,從群體中,選擇抗性基因型的增加,氮素或磷素的缺乏不是考慮的一個因素,因?yàn)?,所有基因的生長都是在一個耕作管理下的。例如,基于相關(guān)性分析產(chǎn)量和抗病性、樹聚類和回歸樹分析( CART)、對應(yīng)和多維標(biāo)度( MDS)。 Mundy和 Beresford( 2020) 研究了番茄灰霉病菌對果實(shí)氮利用回歸糖濃度的關(guān)系分析。 MDS根據(jù)病害的嚴(yán)重程度成功地對 Caber Sauvignon品種分批次處理。使用前打的統(tǒng)計方法可以很容易的使研究人員建立預(yù)測變量和所需特征之間的關(guān)系,主要是提高產(chǎn)量和抗病性。 參考文獻(xiàn) Anonymous.
