Resumo: The aim of this research was to study the relationships between environmental humidity availability and the anatomical characteristics of water conduction and stomatal systems, in five Mexican peach genotypes with different origins (Jalatzingo and Misantla, Veracruz; Temascaltepec, México; Tulancingo, Oaxaca; Sombrerete, Zacatecas), one almond and Nemaguard rootstock. Shoots, leaves and stomata of six months old plants were anatomically characterized by means of 25 characters. The almond tree and the rootstock Nemaguard showed differences in relation to the peaches, which had higher similarity, although they maintained a separation according to their origin. Groups were differentiated by the following characters: stomatal density; width of the leaf upper epidermis; number, frequency and perimeter of xylem vessels; and the index of vulnerability of the leaf central vein, pith, xylem and phloem percentage of the shoot. The conditions of humidity availability of their origin showed strong association with the studied anatomical characteristics, because the environment with more deficit of humidity (Tulancingo and Sombrerete) showed plants with bigger size and smaller frequency of vessels of xylem, as well as low xylem and phloem percentage in shoot, which can be interpreted as resistance adaptations to drought. The area where the occurrence of drought (Jalatzingo) is rare showed the opposite characteristics.

Fueron caracterizados anatómicamente brotes, hojas y estomas de plántulas de seis meses de edad, mediante 25 caracteres. El almendro y el portainjerto Nemaguard presentaron diferencias con respecto a los duraznos, los cuales tuvieron mayor similitud, aunque mantuvieron una separación acorde con su origen. Los caracteres que diferenciaron los grupos fueron: densidad estomática, grosor de la epidermis superior, número, frecuencia y perímetro de vasos, el índice de vulnerabilidad de la nervadura central, y el porcentaje de médula, xilema y floema del brote. Las condiciones de disponibilidad de humedad del origen presentaron fuerte asociación con las características anatómicas estudiadas, debido a que los ambientes con mayor déficit de humedad (Tulancingo y Sombrerete) presentaron mayor tamaño y menor frecuencia de vasos de xilema, así como bajo porcentaje de xilema y floema en brote, lo que puede interpretarse como adaptaciones de resistencia a sequía. La zona donde es rara la ocurrencia de sequía (Jalatzingo) presentó características opuestas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNúñez-Colín, Carlos AlbertoBarrientos-Priego, Alejandro FacundoRodríguez-Pérez, Juan EnriqueNieto-Ángel, Raúl2006-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7129Pesquisa Agropecuaria Brasileira; v.41, n.2, fev. 2006; 233-241Pesquisa Agropecuária Brasileira; v.41, n.2, fev. 2006; 233-2411678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAspahttps://seer.sct.embrapa.br/index.php/pab/article/view/7129/4174info:eu-repo/semantics/openAccess2014-09-25T17:28:37Zoai:ojs.seer.sct.embrapa.br:article/7129Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-25T17:28:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
