7.1.2 Flowering

For flowering , Cantú-Ayala (1990) reported for Prosopis laevigata the period of flowering and fructification in the beginning of March to middle of June during 1965–1986 in Linares, N.L., as well as Alvarado-Vázquez (2003) in the years 2000–2001. According to their observations on H. pallens and Z. fagara, Alvarado-Vázquez (2003) suggested that those species that have been evolutionarily chosen to develop their flower buds with anticipation possibly have adjusted the anthesis of the same ones with certain environmental conditions (e.g., temperature, precipitation, or photoperiod), with which they risk of bringing the buds to maturity when a certain environmental condition occurs and if this condition is not sustained, the flowers may not complete their development, so the plant before this situation opts to abort them early and not invest resources in flowers that will hardly reach the ultimate objective of producing seeds; and to compensate for these losses of reproductive structures, the plant has developed strategies such as (a) forming a large number of buttons and, in a certain favorable environmental condition, maturing only a part of them, (b) the ability to develop newly and quickly, new reproducers of structures, and (c) small flowers to be able to produce many, and in case of loss, the cost is minimal.
