Adaptation of orange (Citrus sinensis L. Osbeck) to climatic conditions in Cusco as a response to climate change

The Cusco Region, due to its geographical and climatic peculiarities, is prone extreme events, such as the increase in average temperature, intense rainfall, agronomic meteorological droughts. Citrus fruits, like oranges, adapt different climates; however, growth, flowering phenology fruit set are affected by changes temperatures lack of rain; therefore, these abiotic factors detrimental citrus production usual scenarios tropical climates. objective research was develop an experiment propose a mechanism adaptation climate change orange (Citrus sinensis L. Osbeck) conditions altitude Cusco, located at 3,302 m.a.s.l. evaluating characteristics production. constitutes quantitative investigation, descriptive correlational type, using non-probabilistic sampling called consecutive sampling. Management consisted pruning, removing thorns applying soil conditioner; evaluation observation phases sprouting, flowering, relative rest, fruiting harvest period; for phenological parameters presented two sprouting flows, first between January-May second, August-September; April-June second September-November; was: 229 fruits/tree/year; diameter 06,44 cm 26,44 kg/tree/year. oranges high altitudes shows change, constituting action economic interest, contributing Peruvian proposal, which committed global response considers it priority update national contributions incorporate objectives change.
