The aim of this research was to evaluate the effect of mepiquat chloride applied at three times and three different doses: in the development, yield and quality of the cultivation of “escabeche” chili pepper (Capsicum baccatum var. pendulum). In this experiment, a 23 factorial arrangement was used in a randomized complete block statistical design (DBCA) with four replications, the analysis of variance (ANVA) and the Duncan comparison test of means at 5% for the factors and levels were performed. The doses and moments evaluated were: mepiquat chloride at d1: 250; d2: 375 and d3: 500 ppm; application times at m1: 20, m2: 35 and m3: 50 days after transplanting. No statistically significant differences were found for the interaction of the dose x moment factor, nor for the moment factor. However, statistically significant differences were found for the dose factor and its levels in the v...

The aim of this study was to characterize and identify groups of achiote (Bixa orellana L.) with characteristics related to increased yield and bixin content. A total of 149 achiote accessions were collected from the departments of Loreto, San Martin, Junín, Pasco, Huánuco, Ucayali, and Cusco, in Perú. These were then evaluated using ten quantitative and three qualitative capsule and seed descriptors. Undesirable characteristics such as high spinosity and dehiscence predominated, while none of the quantitative descriptors correlated significantly with bixin content. Principal component analysis indicates that the quantitative descriptors (except for bixin content) are statistically significant, forming four clusters. Notably, one of the clusters included accessions characterized by heavy seeds, and another cluster included accessions with high number of seeds and bixin content.
