英文摘要	The aim of this study was to explore some physiological and productivity responses of two chili pepper morphotypes (Capsicum annum L.) exposed to different soil moisture contents. A randomized block design in a split-plot arrangement with four replicates was used. The large plots (32 m long and 3.2 m width) were 25% +/- 2 as the optimum soil moisture content (OSMC), and 20% +/- 2 as the suboptimum soil moisture content (SSMC); the small plots (16 m long and 3.2 m width) were two chili pepper morphotypes: Jalape & ntilde;o and Chilaca, respectively. Jalape & ntilde;o plants showed more stability in relative water content (RWC), photosynthetic activity (mu mol CO2/m(2)/s), and a relatively low transpiration (mmol H2O/m(2)/s) and stomatal conductance (mu mol H2O/m(2)/s); therefore, it had a higher number of flowers per plant and number of fruits per plant, consequently recording a high fruit production of 3.94 and 2.99 kg/m(2) in OSMC and SSMC, respectively. In contrast, the Chilaca chili showed low stability in water relative content (WRC), photosynthesis, and transpiration, going from OSMC to SSMC, as well as showed a lower yield in SSMC; however, all of that was compensated by its size and weight of the fruit per plant, with a yield of 4.95 kg/m(2) in OSMC. Therefore, the Jalape & ntilde;o chili pepper could be an option when the irrigation water is limited, and the Chilaca chili pepper when this resource is not limited.
