“…Oliveira, F. Oliveira, & Santos, 2014;Silva, Carvalho, & Duarte, 2013;Silva et al, 2017). Thus, other methodologies have been used in the evaluation of the discharge efficiency such as the Singh Method (1981), based on the Mahalanobis distance (D²), which considers less important the characteristics that present lower variability (Chagas, Alexandre, Schimildt, Bruckner, & Faleiro, 2016).…”

This study aimed at selecting determinant morphoagronomic descriptors to characterize and evaluate Physalis angulata L. germplasm. Twelve quantitative and twenty-two qualitative descriptors were analyzed in six accessions of P. angulata coming from the physalis germplasm collection belonging to the State University of Feira de Santana-BA. The selection and discharge of quantitative descriptors was based on the direct selection and on the Singh method, while qualitative descriptors were analyzed through entropy. The statistic analyses were carried out using the GENES and R programs. Ten quantitative descriptors were excluded through direct selection and five through the Singh method. However, only four descriptors were considered redundant by both methods: east-west fruit, weight of five ripe fruits, width of leaf blade and total soluble solids. Although the total soluble solids descriptor was appointed for discharge, it was included in the group of descriptors selected due to its importance in the characterization of physalis fruit. The list of minimum descriptors to describe physalis accessions comprised 15 descriptors: plant height, stem diameter, north-south fruits, number of fruits per plant, leaf blade length, internode length, fruit longitudinal length, fruit transversal length, total soluble solids, growth habit, stem color, leaf margin shape, unripe calyx color, unripe fruit shape and color. These were nine quantitive and six qualitative descriptors, respectively. The discharge of 55.88% of the descriptors did not cause significant loss of information and might allow the reduction of time and resources spent to characterize and evaluate physalis germplasm.

“…Regardless of ETo rate applied, all fruits showed higher diameters of 55 mm, the minimum required to be classified as commercial (Chagas et al, 2016). The results were superior to those mentioned by Cavichioli et al (2008) studying irrigated passion fruit in artificial lighting conditions, finding 77 mm for LFD and 69 mm TFD.…”

“…There was difference of 31% in income values between the lowest and highest irrigation levels ( Figure 4D). This results are above 50% yield required by the processed market, with fruits suitable for consumption in natura and for industry (Chagas et al, 2016;Silva et al, 2016a). However, this increase in pulp yield may be related to the reduction in peel thickness occurred with water replacement rates above 100% of ETo.…”

The drought stress is an important factor for crops in areas with low rainfall as in the semiarid regions and affects immediately the physiological processes and plant production. However, irrigation is an essential practice to minimize effects of drought stress since the appropriate management is done it can increase the farm income. This study aimed to analyze the photochemical and productive performance of passion fruit (Passiflora edulis) hybrid 'BRS Gigante Amarelo' irrigated in a Brazilian semiarid region. It was studied four water replacement rates (33, 66, 100 and 133% of ETo) at field conditions. A randomized block design was used with five replications and the fluorescence of chlorophyll a, yield and fruit quality were evaluated. The photochemical efficiency of photosystem II has been changed along the day at high temperatures occurring evidential damage in PHS II. Water replacement between 100 and 133% of ETo (1032 mm year-1) promoted the best production rates and quality of the fruit, however the size of the fruit and bark thickness are reduced by over 100% ETo.

Accessions of macaw palm fruits from the State of Goias, Brazil were characterized aiming the identification of groups with similar characteristics and indicate groups with higher agronomic potential, using multivariate tools. Fruit were harvested with completed yellow fruit bunches without whitish scores. The evaluated variables were fruit and almond length, fruit and almond diameters, fruit and dehydrated almond weight, average number of almonds, oil percentage of almond and dried fruit. The genetic diversity of populations was evaluated by Ward’s clustering method and Person´s correlation was obtained to evaluate the relative importance of each characteristic and variance analysis associated with Tukey´s test to verify the group’s effects. The studied population demonstrated great variability. The characteristics that most contributed to the variability were fruit weight and diameter and the almond´s oil percentage. Ward´s group analysis revealed six groups of similarity, being significant for all evaluated characteristics. Group VI stood out for all evaluated characteristics and group III presented the best averages for the almond´s weight and almonds and dried fruit oil percentage.
