Abstract

The papaya (Carica papaya L.) is an economically important crop in Mexico and Latin America. The nursery phase plays a primary role in the production process, at this stage, it is susceptible to pests and diseases. The use of biofertilizers based on entomopathogenic fungi (EF) is an alternative to produce healthy and quality seedlings, through biological agriculture. The objective was to evaluate the ability of Beauveria brongniartii and Purpureocilium lilacinum to colonize tissues, promote emergence and improve the plant quality of two papaya genotypes in nursery. An experiment with factorial design A×B was established [A = papaya genotype (hybrid '“Intenzza” and var. “Maradol”) and B = inoculation of B. brongniartii (Bb), P. lilacinum (Pl) and without microorganism]. Emergence percentage (EP), Plant Height (PH), Stem Diameter (SD), Fresh Biomass (FB) and Dry Biomass (DB), endophytism, Lignification Index (LIGI) and Dickson Quality (DQI) were quantified. EP increased (6%, P = 0.0043) with Bb inoculation. Both EF increased the PH (P = 0.00001) by 0.38 (Bb) and 0.37 cm (Pl), and the ST (P = 0.00001) by 0.24 (Bb) and 0.23 mm (Pl), respectively. Aerial and root FB (P = 0.0003) increased with Bb and Pl by 0.16 and 0.1 g, and 0.17 and 0.1 g, respectively. LIGI (P = 0.0128) and QDI (P = 0.0433) were higher with Bb. Both EF colonized different plant tissues. Bb inoculation promoted seed emergence, both EF were able to colonize endophytically different organs of the plant and favored its quality.

两种基因型番木瓜(Carica papaya L.)接种昆虫致病真菌后的出苗、生长和植株品质

番木瓜（Carica木瓜L.）是墨西哥和拉丁美洲的一种重要经济作物。苗圃阶段在生产过程中起着主要作用，在这个阶段，它容易受到病虫害的影响。使用基于昆虫病原真菌（EF）的生物肥料是通过生物农业生产健康优质幼苗的一种替代方法。目的评价白僵菌（Beauveria brongniartii）和紫丁香紫丁香（Purpureocillium laveninum）对两个木瓜基因型在苗圃中定植组织、促进出苗和提高植株质量的能力。建立了一个因子设计A×B的实验[A=番木瓜基因型（“Intentza”和变种“Maradol”的杂交种），B=接种B.brongniartii（Bb）、P.laveninum（Pl）和无微生物]。对出苗率（EP）、株高（PH）、茎径（SD）、新鲜生物量（FB）和干生物量（DB）、内生菌、木质化指数（LIGI）和Dickson质量（DQI）进行了定量。接种Bb后EP增加（6%，P=0.0043）。EF均使PH（P=0.0001）分别增加0.38（Bb）和0.37 cm（Pl），ST（P=0.00001）分别增加0.24（Bb）和0.23 mm（P1）。地上部和根部FB（P=0.0003）随Bb和Pl的增加分别增加0.16和0.1g，以及0.17和0.1g。LIGI（P=0.0128）和QDI（P=0.0433）随Bb的增加而增加。Bb接种促进了种子的出苗，两种EF都能定殖植物内生的不同器官，有利于其品质。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
