“…Similar behavior was observed by Lima et al (2012) who verified that the maximum dry biomass and seedling length of Poincianella pyramidalis [(Tul.) L. P. Queiroz] coincided with the moment that the seeds also had the highest germination speed index.…”

Hovenia dulcis is a pioneering species, fast growing and considered exotic and invasive. The species has multiplicity of uses and reproduces by seeds. In this sense, it is extremely important to know the physiological maturity of H. dulcis seeds. The objective of the research was to determine if the maturation of H. dulcis seeds is achieved concomitantly with the physiological maturation of the false fruit. Seeds were obtained from seven adult trees located in Marechal Cândido Rondon, PR. The fruits were classified in five maturation stages, determined according to color chart. In order to verify the effects of the maturation stages of the false fruit on the physiological maturity seeds biometric characteristics, moisture content, germination, vigor and seedling development were evaluated. Seeds of H. dulcis presented evolution of maturation at the same time as the false fruit. For the evaluated parameters, seeds classified as stage 1 (7.5 YR 5/8) showed the best results for seed germination and seedling development, in contrast to those classified as stage 5 (2.5 YR 3/4), which presented low germination and delay in the development of seeds and seedlings.

“…At site 1, seedlings with greater accumulation of dry matter were obtained from the stage when the fruits were orange color and with greater length from yellow fruits (Table 3). Lima et al (2012) have found that the maximum dry matter content and length of seedlings of Poincianella pyramidalis [(Tul.) L. P. Queiroz] coincided with the time when the seeds had a higher germination speed index.…”

This study aimed to determine the physiological maturity of A. edulis seeds, check if this is achieved in the same maturation stage, regardless of the collection region and, colorimetry of the fruit can be indicative of the time of harvest. Fruits were harvested in three counties of the western region of Paraná and visually classified into five ripening stages according to the color of the pericarp with the help of a digital colorimeter. Analyzed seed variables included morphological characteristics, germination and vigor. The experiment was conducted in a completely randomized design with four replications. The maximum dry matter accumulation of seeds was reached when the fruits reached the color orange. With the advance of the ripening process, red color fruits had seeds with lesser moisture content, coinciding with the maximum germination percentage and speed, besides generating seedlings with larger size and biomass accumulation. The green spectrum allowed to discriminate maturity from different places of harvest. A. edulis seeds with physiological maturity should be harvested when fruits present the red color, independent of the harvesting region or, with reflectance values between 28.0 and 49.2 nm in the green range of the color spectrum.

“…The variation between the seed physiological quality of different M. caesalpiniifolia trees in this study may be considered lower than of tree species such as Poincianella pyramidalis (Tul.) L.P. Queiroz (LIMA et al, 2014) and Sideroxylon obtusifolium (Roem. & Schult.)…”

“…High-quality seeds and technical planning are required for all production stages, starting with the selection of trees from which the seeds will be collected MEDEIROS, 2007). Therefore, seed quality control in the laboratory is necessary prior to the selection of suitable trees (LIMA et al, 2014).…”

Mimosa caesalpiniifolia Benth. (Fabaceae) is a native tree of the dry tropical forests of northeastern Brazil and can be exploited for logging and reforestation purposes. This study evaluated the physiological quality of seeds and the genetic diversity of a cultivated population of M. caesalpiniifolia, against the background of potential commercial seed production. Nine trees were used in the study. The quality of their seeds was evaluated by germination and vigour tests, and their genetic diversity was accessed using Inter Simple Sequence Repeat (ISSR). The studied tree group presents a moderate genetic diversity and produces seeds with high physiological quality, but with subtle vigour differences, which can be detected by electrical conductivity and potassium leaching tests. Our results suggest that these trees are potentially suitable for commercial seed production.
