Se utilizó un diseño experimental aleatorizado (DCA), con 4 tratamientos y 3 repeticiones para un total de 12 unidades experimentales. Los tratamientos fueron: turba (T1) (testigo), vermicomposta (T2), vermicomposta + composta de bagazo de maguey mezcalero (T3) y composta de bagazo de maguey mezcalero (T4). Los sustratos evaluados presentaron partículas entre 0.25 y 2 mm. La densidad real en las compostas variaron de 1.82 a 1.91, la porosidad del aire osciló de 24-13.33%. Las plántulas cultivadas en vermicomposta + bagazo de maguey (50:50 v:v) (T3) y en bagazo de maguey mezcalero, presentaron la mayor altura (12.29 y 13.07 cm respectivamente) y el mayor diámetro de tallo. Las plántulas cultivadas en vermicomposta obtuvieron el mayor número ...

En el invernadero del Laboratorio de Suelos del CIIDIR- Unidad Oaxaca, en 2009, se realizó un experimento bifactorial con arreglo combinatorio con cuatro repeticiones y distribución de tratamientos en bloques aleatorizados completos. Los factores experimentales y sus niveles fueron: factor A: plántulas de maguey propagadas por hijuelos vegetativos (HI) y por bulbilos florales (BU); factor B: seis inóculos de consorcios nativos de HMA provenientes del distrito de Tlacolula, Oaxaca (CN1 a CN6), control positivo Glomus intraradices (GI) y control absoluto sin inocular (CON). Las variables de respuesta fueron: altura de la planta, área foliar por planta, longitud y distribución de raíces y biomasa a la cosecha (pesos fresco y seco de hojas, tallo y raíces), ...

a variety of edaphoclimatic conditions; this has allowed
farmers in the state of Oaxaca given its orography to select
materials that suit their particular conditions. This work was
performed at the Technological Institute of Oaxaca Valley
(ITVO), in order to evaluate collections of native bean
seeds (Phaseolus vulgaris and Phaseolus lunatus) from
the Central Valleys of Oaxaca on their physical, nutritional
and germination capacity under water stress conditions
generated by the addition of osmolytes in the germination
media. It was able to observe biological variation in terms of
physical characteristics related to size, color and weight. The
results indicate that in relation to the nutritional composition
of these collections, show content of protein, fat and crude
fiber at rates similar to those reported in other studies.
Germination capacity varied between collections even in
normal conditions (control), the lowest value had it frijolon
(big bean) (52.5%), while the collection negro delgado (thin
black), blanco delgado (thin white), negro grueso (thick
black) and colorado (red) had the highest germination rate
under water stress. Polietilenglycol (PEG) was the osmolyte
that reduced germination capacity of seeds and in the case
of sucrose was found that this favored the germination rate
over the other osmolytes used.

properties of four substrates obtained from agricultural
waste used for the production of seedlings of pepper
'onza' as an alternative to the use of conventional
substrates. It was used a completely randomized design
(DCA) with 4 treatments and 3 replicates for a total of
12 experimental units. The treatments were: peat (T1)
(control), vermicompost (T2) + vermicompost + compost
of mezcal maguey bagasse (T3) and compost of mezcal
maguey bagasse (T4). The substrates tested had particles
between 0.25 and 2 mm. The actual density in the compost
ranged from 1.82 to 1.91, air porosity ranged from 24-
13.33%. Seedlings grown in vermicompost + maguey
bagasse (50:50 v: v) (T3) and mezcal maguey bagasse
showed greater height (12.29 and 13.07 cm respectively)
and the highest stem diameter. Seedlings grown in
vermicompost obtained the highest number of leaves
(9.25), while the largest stem diameter was observed in
seedlings grown in vermicompost + compost of maguey
bagasse and compost of mezcal maguey bagasse.
