“…Although these authors indicate that this equation can be used for other commercial pineapple cultivars, such as 'Pérola' and 'Smooth Cayenne', the ideal and more recommended is that the use of these models is specific for a cultivar. This explains the differences in the models fitted between the present study and the mentioned work, and is justified by the differences in morphology and growth behavior and inherent production of each cultivar that are observed under commercial and experimental conditions (PEGORARO et al, 2014;MAIA et al, 2016).…”

The estimation of pineapple total leaf area by simple, fast and non-destructive methods allow inferences related to carbon fixation estimative, biotic and abiotic damages and correlating positively with yield. The objective was to estimate D leaf area and total leaf area and of ‘Pérola’ pineapple plants from biometric measurements. For this purpose, 125 slips were selected and standardized by weight for planting in pots. Nine months after planting in a greenhouse, the plants were harvested to evaluate the total leaf area of the plant, D leaf area and D leaf length and width using a portable leaf area meter. Pearson correlation analysis was made and it was observed significative positive and strong correlation among the studied variables. Then, regression models were adjusted. It was observed that the D leaf area of ‘Pérola’ pineapple can be estimated from the length and width of this same leaf and the total leaf area can be estimated from the D leaf area.

“…Vitória seedlings propagated in vitro, planted in a greenhouse and induced to flowering at nine months. Pegoraro et al (2014) and Vilela et al (2015), working with pineapple cv. Vitória, irrigated, grown between March and April 2009 and induced in July 2010, obtained 82 cm and 86.75 cm in length of "D" leaf, respectively, that is, a difference of up to 30.65 cm in relation to plants of the present study.…”

By considering the few studies related to pineapple cv. Vitória, to know the relationships between the physical and chemical characteristics of the fruits, and they with the “D” leaf, is fundamental. The objective of this work was to evaluate the relationships between “D” leaf, with the physical and chemical characteristics of fruits of pineapple cv. Vitória, under the edaphoclimatic conditions in the North of the State of Espírito Santo. The experiment was carried out in a complete randomized block design in split-plot arrangement with four replications. The data obtained from 433 individually evaluated fruits were analyzed, as it follows: 84 at planting in July and induction at 8 months; 98 at planting in July and induction at 10 months; 84 at planting in July and induction at 12 months; 59 at planting in September and induction at 8 months; 50 at planting in September and induction at 10 months; 58 at planting in September and induction at 12 months. Pearson’s correlation was performed between the characteristics of “D” leaf (length and width) and the physical and chemical aspects of fruits (mass of the fruits with and without crown, fruit length and diameter, pulp volume, translucent area, soluble solids and titratable acidity) for the six treatments. Most of the relationships among the 11 characteristics evaluated were of low magnitude in the six treatments, but correlations of high magnitude and practical application of interest to plant scientists, breeders, farmers and consumers were found. The length and width of the “D” leaf should not be used as indicators of physical and chemical qualities of cv. Vitória. Fruits with higher mass, with or without crown or larger width or diameter present higher pulp content. Fruits with higher mass, with or without crown have lower content of soluble solids.

“…Studies were developed for irrigated pineapple grown in semiarid regions (Franco et al, 2014;Pegoraro et al, 2014;Maia et al, 2016); however, information about physiological characteristics of this crop irrigated with saline water is lacking, making field studies with pineapple subjected to saline conditions necessary (Elhag and Elzain, 2012).…”

Studies determining physiological characteristics of field-grown pineapples irrigated with low-quality water are lacking. This work evaluated the photochemical efficiency of ‘Pérola’ pineapple irrigated with saline water in the semiarid region of Bahia, Brazil. The experiment was carried out in randomized blocks with five treatments consisting of the following irrigation depths: 100% of ETc using water with electrical conductivity (ECw) of 0.75 dS m-1; and 50, 75, 100 and 125% of ETc using water with ECw of 3.6 dS m-1. Chlorophyll a fluorescence measurements were made over the course of 13 months using a pulse-modulated fluorometer, in all treatments. Quantum efficiency (Fv/Fm) fluctuated throughout the cycle of the pineapple with values below the ideal, especially at the end of the crop cycle. Quantum yield of photosystem II (Yield), photochemical quenching (qP), non-photochemical quenching (NPQ) and chlorophyll fluorescence decrease ratio (RFd) were not influenced by irrigation depths. Therefore, energy used for photosynthetic processes in pineapple plants is not affected by irrigation using saline water with electrical conductivity of 3.6 dS m-1.
