El propósito de esta investigación fue estudiar las relaciones ambientales de disponibilidad de humedad, con las características anatómicas del sistema de conducción de agua y estomático, en cinco genotipos de duraznos mexicanos con diferentes orígenes (Jalatzingo y Misantla, Veracruz; Temascaltepec, México; Tulancingo, Oaxaca; Sombrerete, Zacatecas), un almendro y el portainjerto Nemaguard. 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. |

A study was carried out using data from 341 FAO-ANDA-ABCAR soil fertility experimental sites in the state of Minas Gerais, Brazil. The main purpose of this study was to provide crop yield information and an economic interpretation of the ability of soil classes to produce net income following fertilizer applications. The soil classes studied were those mapped in the on-going soil survey of the state of Minas Gerais. These objectives were accomplished by: a) selecting the main eash crops in the state; b) grouping experimental sites into soil classes and phases according to Brazilian soil survey criteria; c) estimating yields by soil class for individual crops with and without fertilizer application; d) computing check yield productivity indexes (PI-1) and net income productivity indexes (PI-2) and e) examining the relationships between corn yields with fertilizer and soil analysis values. Fifteen soil classes and 10 different phases of these soil classes were identified on the FAO-ANDA-ABCAR sites. Of the soil classes and phases identified, 206 were on soils with cerrado flora, 79 with tropical forest, 42 with "wet" tropical forest and 14 with "wet" meadow. Soils under cerrado vegetation appeared to be generally different from those under forest environment with respect to their soil test values and yielding ability. Comparisons between soil classes suggested that the level of base saturation (eutrophic, dystrophic) by itself did not provide sufficient information to estimate their yields.
