In order to obtain the effect in the intensive production of apple pepper (Capsicum pubescens, R., L. y P.) and reproductive beha-viour it was evaluated four shade levels (90, 70, 50, 30%) and control treatment (0% shade). Vegetative behaviour was evaluated in terms of length, diameter of the main stem; the number and length of branch of the main stem; the number and length of the shoots, the number and length of the branches; dry and fresh weight of foliage and root. Reproductive behaviour was evaluated in function of the flower number. The experiment started on August 18, 1996 to January 1997, in the Cerro de la Estrella, Mexico City, in green-house conditions and using dripping irrigation. The experiment design consisted of random blocks, with three repications. Correla-tions matrices were realized and regression equations resulted for the variables that presented the smallest regression mean square error. Six samplings were taken for the stem of three random plants for experimental unit and one destructive sampling was done in nine random plants for treatment. The development of the control plants was in disadventage and was affected by sunlight in sum-mer; plants under the 90% of shade treatment presented elongation because of the low level of sunlight, the 30 to 70% of shade treatments, promoted vegetative and reproductive development.
