Abstract
Citrus crops are subtropical, but they are widely cultivated in most of
tropical countries, all over the world. The most important industry of
citrus is located in the subtropical zone, and this is the place in which
almost all of the scientific information has been generated. Under sub -tropical conditions, the main weather factor that influences the growth
and development of citrus plants is the variation of the temperatures
related to the annual season cycles (summer-winter). Under tropical
conditions, on the other hand, the main factor is the presence or ab -sence of rains. In tropical zones, citrus are cultivated from 0 to 2000
meters above the sea level. Depending on the altitude, regions for cul-tivating citrus in the tropic are classified as high tropic (1500 to 2000
meters), mid (800 to 1500 meters) or low (0 to 700 meters). With al-titude changes, the temperature modifies the annual sum of heat units
accumulated, a very important factor to choose the varieties to cultivate
in every thermal floor.
As a development model of the crop, in the Corpoica´s La Libertad
research center, located in the Meta foothills (low tropic, acid soils and
well drained high terraces) research about citrus has been being made
since 1997. This chapter shows the most relevant information obtained
from the studies about phenology, plant nutrition, potential of perfor -mance, requirements and water balance, induction of the flowering,
fruit’s growth and the response of 26 orange phenotypes to the envi -ronmental local offer.
