“…The fruits were taken to a laboratory and cut open. The seeds were removed, washed in running water in a nylon sieve to remove the pulp, dried for two days at room conditions to remove excess moisture, and then cleaned, and stored in a cold room at 7°C (Silva et al, 2015).…”

Passion fruit is a native fruit of tropical America, with Brazil being the world's leading producer and consumer of this fruit, with an estimated annual production of 554,598 Mg, and yield of 13,500 kg.ha-1 Phenotyping through digital images has been used to evaluate morphological characteristics of seeds. Knowledge of the degree of genetic divergence plays an important role, as it assists in the adoption of appropriate strategies for improvement in passion fruit populations.. The objective of this work was to estimate the genetic divergence among full-sibling families of passion fruit through morphophysiological characteristics of seeds using the Ward-Modified Location Model (Ward-MLM) method. Seeds of 98 full-sibling families (FSF) of passion fruit from the breeding program of the Mato Grosso State University were evaluated considering physiological descriptors of seeds, using germination and vigor tests; and morphological descriptors of seeds, using a digital imaging seed analysis device and software. We found that the Ward-MLM method was efficient in detecting genetic divergence using seed morphological and physiological descriptors, simultaneously. The descriptors that contributed the most to the genetic divergence among ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (3): gmr18331 L.R. Fachi et al. 2 FSF were those related to seed geometry. This method formed three heterotic groups. Group II had the largest mean emergence speed index (1.106) and seedling emergence percentage (65.8%), and Group III had the largest means of seedling dry weight (4.140 g), radicle length (6.30 mm), germination speed index (2.503), and seed germination percentage (90 %). We conclude that crosses between FSF groups II and III are a good option to improve seed characteristics.

“…A number of methods are recommended for aryl removal in passion fruit seeds such as water fermentation (Silva et al, 2015), using a blender (Ferreira et al, 2007), seed friction mixed with sand (Aguiar et al, 2014), degumming in water (Aguiar et al, 2014) and immersion in virgin lime solution (Martins et al, 2006). Implementing these techniques aims to improve the seed performance; however, some negative effects may occur due to inadequate performance of the procedures/techniques, leading to physical or physiological damage occurring.…”

“…Damage to physical and physiological quality caused to passion fruit seeds subjected to aryl removal methods is generally difficult to identify since they may not be visible and may have latent effects (Silva et al, 2015). An alternative for accurately evaluating these seeds is to use X-ray imaging analysis techniques to identify mechanical damage and seed deformations.…”

Passion fruit seeds present germination problems which are mainly attributed to growth regulating substances present in aryl. The objective of this work was to evaluate the quality of passion fruit seeds submitted to different aryl removal methods by the X-ray test compared to the traditional viability and vigor tests. Seeds extracted from giant yellow passion fruit were purchased from a local market and then subjected to the following aryl removal techniques: water degumming, sand rubbing, mechanical blending, fermentation and virgin lime. After aryl removal, the seeds were submitted to a physiological quality evaluation by the moisture degree, germination, first germination count, germination speed, and seedling length, and also a physical quality evaluation by X-ray test. The treatments using fermentation and virgin lime were harmful to the seeds and the aryl removal techniques of passion fruit seeds by means of degumming in water, sand friction and mechanically with a blender presented the best results. The X-ray test was efficient in identifying mechanical damage and deformations in passion fruit seeds.

“…Plant propagation of passion fruit in commercial fields is preferentially through seeds, seminiferous (Silva et al, 2015), but lack of uniformity of germination and seedling emergence is reported by producers and nurseries, which creates difficulties in raising quality seedlings and establishing productive orchards. This lack of uniformity is related to the dormancy process present in various species of Passifloraceae, as reported by Osipi and Nakagawa (2005) in Passiflora alata Dryander, by Zucareli et al (2009) in Passiflora cincinnata Mast., and Zucareli et al (2015) in Passiflora incarnata L.…”

-Seedlings for commercial growing of passion fruit are preferentially acquired through seeds. Success in germination and seedling emergence, in turn, is influenced by the genetic constitution of the progenies and the thermal conditions imposed on the growth environment. The aim of this study was to evaluate the emergence and vigor of seedlings of passion fruit cultivars exposed to different temperatures. The experiment was conducted in a germination chamber at the Unidade de Ensino, Pesquisa e Extensão / Pomar Campus of the Department of Plant Science of the Universidade Federal de Viçosa (UFV). The study was carried out in 5 × 3 factorial arrangement, with five temperature ranges (5-15, 10-20, 15-25, 20-30 and 25-35 °C) and three varieties of passion fruit (BRS Sol do Cerrado, BRS Gigante Amarelo and FB-200 Yellow Master) in a completely randomized design with six replications of 25 seeds per plot. The variables analyzed were the percentage, the speed index, and the average time of emergence, shoot length, total length, and seedling dry matter. The cultivars BRS Sol do Cerrado and BRS Gigante Amarelo exhibited seedling emergence of over 95% in the temperature ranges of 20-30 °C and 25-35 °C. Alternating temperatures from 20-30 °C stimulates seedling emergence, seedling growth, and greater accumulation of seedling dry matter.Index terms: Passiflora edulis Sims, cultivars, seeds, thermal conditions. Emergência e vigor de plântulas de maracujazeiro azedo em função da temperatura RESUMO -A propagação de plantas de maracujazeiro azedo, em plantios comerciais, é realizada preferencialmente por meio de sementes. O sucesso da germinação e emergência de plântulas, por sua vez, é influenciado pela constituição genéticas das progênies e pelas condições térmicas impostas no ambiente. O objetivo neste trabalho foi avaliar a emergência e o vigor de plântulas de cultivares de maracujazeiro azedo sob exposição de diferentes temperaturas. O experimento foi conduzido em câmara de germinação na Unidade de Ensino, Pesquisa e Extensão/Pomar Campus pertencente ao Departamento de Fitotecnia da UFV. O trabalho foi desenvolvido em esquema fatorial 5 × 3, com cinco faixas de temperatura (5-15; 10-20; 15-25; 20-30 e 25-35 °C) e três cultivares de maracujazeiro azedo (BRS Sol do Cerrado, BRS Gigante Amarelo e FB-200 Yellow Master) no delineamento inteiramente casualizado e seis repetições de 25 sementes por parcela. As variáveis analisadas foram as percentagem, índice de velocidade e tempo médio de emergência, o comprimento da parte aérea e total e massa seca de plântula. As cultivares BRS Sol do Cerrado e BRS Gigante Amarelo apresentaram emergência de plântulas acima de 95% nas faixas de temperaturas de 20-30 °C e 25-35 °C. Temperaturas alternadas 20-30 °C estimulam a emergência, o crescimento e maior acúmulo de massa seca das plântulas.
