PERSPECTIVES OF PHYSIOTECHNICS IN FRUIT TREES

Abstract

It is important to know and understand the physiological processes associated with the development of fruit trees, in order to
generate bases for the genetic improvement and for the management of the different fruit species, both at the nursery and
production and post-harvest. During recent years, important advances have been made in the knowledge of the biological and environmental factors that influence the development of fruit trees; However, this has not been as fast as in annual crops, which is due among other causes to the following: a) Its slow development compared to that of annual crops. b) Variations between species in terms of the relationships between vegetative and reproductive growth. e) Existence of periods of growth arrest. d) Strong variations in plant cover throughout the period of active growth. e) Marked importance of the propagation and establishment of orchards in the production of fruit trees, which does not occur in annual crops. t) A large number of cultural practices that modify the development potential, precisely due to the inherent characteristics of fruit trees. In general, it can be stated that plant physiologists seek to define the production potential of the plant and understand the factors that limit its expression, for which research is carried out at different levels and with different approaches. Below are some research needs in fruit trees.
