Some of these books only provide extensive lists of species, 3 examples of mutualism in the desert indications of their edible parts, while others add descriptions and illustrations of the species. The highest production between 1, and 1, kg DM 3 examples of mutualism in the desert -1 was obtained with lucerne in the first group, with no differences detected among the cultivars. Chungara 38 2 : Edible weeds, however, are scarcely used in many countries, and weed gathering is more of a weekend hobby than a regular source of food supply. To determine the effectiveness of gray foxes and coyotes as vectors, we established 3 treatments to compare germination rates of fresh seeds with those that went through the digestive tract of the dexert. Plant morphology may be described generally in terms tje growth form, above- and belowground structures, and size. The data from Table 7 show that edible, non-weedy plants comprise between 6 and 21 percent of the biomass of the natural communities surveyed.

In experiment 2, eight additional genotypes from two perennial legume species were established in May seven cvs. The study area received very low rainfall in two of the three experimental years andand therefore, the evaluation of perennial legumes was conducted under the most extreme conditions expected. For example, the availability of water is a function of soil texture, structure, and depth, in addition to position within the landscape. Shreve, F. Christie, A. References Acuña, H.
