常見例句Occurrence, development, and mechanism of planthopper insecticide resistance are discussed, along with proliferation of the resistant biotypes. 對(duì)褐飛虱抗藥性的形成和發(fā)展及其抗藥性機(jī)理等方面進(jìn)行了綜述，并對(duì)該蟲的再猖獗進(jìn)行了探討。Briselden AM, Hiller SL. Longitudial study of the biotypes of Gardnerella vaginalis. J Clin Microbiol 1990;28:2761. 吳愛武;陳艷珍.;陰道加德納菌生物型與細(xì)菌性陰道病的關(guān)系RESULTS Eleven biotypes,18 antibioticgrams,9 serotypes and 18 plasmidgrams were detected in the 97 strains. 結(jié)果97株菌分11個(gè)生物型，18個(gè)抗菌譜型，9個(gè)血清型與18個(gè)質(zhì)粒譜型，但分型率高低不一。The result of such combined effects of the genetic system and the environment is strong homozygosity of the biotypes found by the author. 遺傳系統(tǒng)和環(huán)境的這種聯(lián)合效應(yīng)的結(jié)果，使作者看到了生物型的強(qiáng)純合性。The only disadvantage is that it may trigger the selection of new biotypes that are able to attack the resistance cultivars. 唯一不利之處是可能促進(jìn)新生物型的選擇，危害抗蟲品種。In this paper, 37 biotypes of citrus plants are studied by means of numerical taxonomic methods on the basis of their 123 characters. 本文對(duì)柑桔類植物的37個(gè)種或類型,在122個(gè)性狀的基礎(chǔ)上進(jìn)行了數(shù)量分類學(xué)研究。 返回 biotypes
