    MANAGEMENT AND SILVICULTURAL PRACTICES AP­ PLIED TO PINE-OAK FOREST IN DURANGO, MEXIC01 by Victor M. Hernandez C., Francisco J. Hernandez, and Santiango S. Gonzales2 ' StudyAr~o Durango state is located in the northwest region of Mexico. It is surrounded by Chihuahua • state in the North and Northeast, Coahuila and Zacatecas in the East, Jalisco and Nayarit in the South, and Sinaloa in the West (lnegi~ 1988; Zavala, 1985). It has an area of 11,964,800 hectares. Half of Durango territory is located on the Sierra Madre Occidental with a 125 km width, 425 km length and mean altitude of 2500 m. The remaining area is· located on the altiplanicie (high plain) Mexicana. The lowest altitude record is regiStered at Tamazula, Durango, with 250 m and the highest record reaches 3,300 m at the Huehliento Mountain. According to the broad diversity in climatic and phys~ographic conditions throughout the state,·Durango is divided into four regions, each one with characteristic types of vegetation. These physiographic regions are: 1. The Quebradas Region - It is characterized by its tropical type of vegetation (deciduous tropical forest and semi-deciduous tropical forest). It is located on the west side of the Sierra Madre Occidental, in an altitude range from 27 to 500m; with a warm and subhumid climate and a summer rainy season. The annual mean precipitation is 1250 rom in this region (Zavala, Z. 1982, Gonzalez, S. 1985). 2. The Mountains or Central Region - It involves the highest elevations of the . Sierra Madre Occidental, and it is mainly covered by coniferous forest (pure pine forest, mixed pine-oak forest, and grassland-shrubs forest).

SUMMARY Somatic embryogenesis can be used for the rescue of threatened forest species. In this research work, the effect of the medium on the germination of Arbutus xalapensis zygotic embryos and 2,4-D growth regulator on induction of embryogenic callus was studied. Strawberry tree fruits were disinfested and the zygotic embryos of seeds were removed and put on MS, WPM and P889 mediums; while for induction of embryogenic callus, they were cultured on MS and WPM. The germination of embryos was affected substantially by culture medium used, being the WPM where 58 % of germination of zygotic embryos was obtained, compared with P889 and MS with 0 and 2 % germination, respectively. Zygotic embryos were placed on MS and WPM medium added with 0, 1, 2, 4 and 8 mg L-l 2,4-D, under light and dark conditions for 30 days. Embryos cultured in MS, and left under low light conditions, had not effect to any treatment to which they were subjected; however, under darkness condition embryogenic callus formation was possible to be induced in the concentration of 1 mg L-1 2,4-D, while on WPM in light condition, the formation and growth of embryogenic callus was achieved by adding 2 mg L-1; under darkness required only 1 mg L-1.

  • Effects of the Eruption of Paricutin Volcano on Landforms^ Vegetation, and Human Occupancy
    Effects of the Eruption of Paricutin Volcano on Landforms^ Vegetation, and Human Occupancy JOHN D. REES INTRODUCTION The environment and rural economy of the Itzicuaro Valley, Michoacán, in west-central Mexico was disrupted on 20 February 1943, by the eruption of a volcano 2 km from the Tarascan Indian village of Paricutin. The onset of the Paricutin eruption was preceded by 2 weeks of mild earthquakes that grew in intensity before the outbreak, after which the seisms and underground noises ceased (Foshag and González 1956:355). The eruption took place at about 4:30 p.m. on a maize field located in a small shallow valley 2 km southeast of the village. The village of Paricutin is located 320 km west of Mexico City in the state of Michoacán in the west-central portion of the Mexican volcanic axis known as the Meseta Tarasca. The Meseta Tarasca is formed of Tertiary and Quaternary volcanic rock materials overlying older sediments and extrusives of the southern escaöment of the Central Mexican Plateau. The cone of Paricutin Volcano is situated on the northern flank of Tancit- aro, in the upper watershed of the westward-trending Itzicuaro Valley (Figure 9.1). Tancitaro is an eroded major Pleistocene volcano that rises to over 3845 m to make it the dominant volcano of the region. To the northeast of the Paricutin cone, another volcano, the twin peaks of Angahuan rise to over 3290 m. The Paricutin cone is the most recent of the more than 150 cinder cones that are identified within approximately 1600 km^ around the newest cone (Williams 1950:168).
