Variation of the internal quality of the pepper fruits (Capsicum annuum L.) under drought condition whit Biobrás-Plus applications

With the objective to evaluate the variations of the internal quality of the peppers fruits, “Español” variety, cultivated under humidity condition and with the bioestimulant application (Biobrás - Plus), were carried out experiments in two locations of the Granma county during the year 2009. The bioestimulant was foliagelike applied early in the mornig after fifteen days of being planted and at the beginning of the flowering period. The utilized treatments were distributed at random in a design of blocks with four repetitions. In the second and third harvest were took samples of 10 mature fruits for treatment and repetitions and were sent to the provincial laboratory of soil of Granma to the analysis bromatologic according to the established techniques. An analysis of main components to prove the variations of the attributes of internal quality of the fruits was carried out, using the statistical package STASTISTICA 6.1 for Windows. The results obtained demonstrated that this biostimulant had stimulative effect when were achieved fruits with better quality when the plants were subjected to drought stress conditions, promoting increments in the dry matter, total soluble solids, vitamin C, potassium and calcium independently of the localities.
