“…Seeds taken from mature fruits tend to germinate faster; however, immature fruits (green color) produce seeds with low vigor and low germination power or even infertility (NAKADA et al, 2011). It is sometimes common to believe that seeds from fruits harvested during the senescence stage demonstrate greater physiological quality (ZUFFO et al, 2022). However, this study did not observe the best physiological quality in fruits harvested at stage 4 (red fruitred exocarp), which was the stage close to senescence of the fruits.…”

“…Thus, the study of seed maturation is important to determine the ideal harvesting point, aiming at seed production and quality (ZUFFO et al, 2022). Thus, the objective of this study was to determine the ideal maturation period for collecting fruits to extract seeds for seedling production, as well as to correlate the main morphological characteristics of 'biquinho' pepper seedlings with the Dickson quality index.…”

The ‘biquinho’ pepper is important in Brazilian cuisine, and the production of quality seeds is necessary to guarantee the production of seedlings. Thus, the objective of this study was to determine the ideal maturation period for collecting fruits to extract seeds for seedling production, as well as to correlate the main morphological characteristics of ‘biquinho’ pepper seedlings with the Dickson quality index. The experimental design was completely randomized, with four maturation stages (1 - green fruit: completely green exocarp, 2 - orange fruit: orange exocarp, 3 - transition orange - 20% orange and 80% red, 4 - red fruit - red exocarp) and eight repetitions. Ripe fruits were harvested from the tops of three plants according to the maturation stage. Plant height, number of leaves, stem diameter, dry mass of roots and shoots, and Dickson's quality index were evaluated. Seedlings showed higher quality when seeds were collected from fruits in the orange transition stage - 20% orange and 80% red. The traits that correlate positively with Dickson's quality index are plant height, shoot dry matter, and root system dry matter.

This study aimed to evaluate the biometric characteristics of fruits and seeds of Diospyros inconstans Jacq., germination and formation of seedlings obtained from fruits at three maturity stages, subjected to different temperatures. Biometric data were obtained from 100 fruits and 100 seeds. The determining parameters in the biometry of the fruits were: length, width, mass and number of seeds/fruit and for the seeds: length, width, thickness and mass. In the germination test, a factorial scheme (3x4), three maturity stages (green, intermediate and reddish), and four temperatures (20, 25, 30 and 35 °C) were used. The analyzed variables were: germination, germination speed index (GSI), mean germination time (MGT), time to obtain 50% germination (t50), percentage of seedlings, length and dry mass of shoots and roots, and collar diameter. Fruits and seeds showed greater variation in the parameters fresh mass and number of seeds per fruit. The germination speed index was higher in seeds from reddish fruits, and seeds from green fruits originated better-developed seedlings. Temperatures of 25 and 30 °C are recommended for conducting the seed germination test at the three maturity stages.

Emergence of Coccoloba gigantifolia Melo, Cid Ferreira & Gribel seedlings as a function of raceme and fruit maturation

2023

Coccoloba gigantifolia fruits show uneven maturation within each raceme, which can affect the quality of the seeds. This study aimed to characterize racemes, fruits, and seeds, after harvest, and evaluate the physiological performance of the seeds as a function of the fruit maturation stage. After characterization, two experiments were set up. In the first, a completely randomized design was used, in a 4 (racemes) x 4 (fruit maturation stages: green, half-green, red, and purple) factorial scheme, with 4 replications. In the second, a randomized block design was adopted, in a 4 (fruit maturation stages) x 2 (with and without seed drying) factorial scheme, with 4 replications. Fruit maturation occurs progressively within each raceme, with fruits from completely green to completely purple in color existing at the same time. In propagation, preference should be given to harvesting racemes with a greater number of fruits in the half-green, red, and purple stages, since seeds from green fruits have low physiological quality. In addition to the variation in emergence as a function of fruit maturation, the seeds of the different racemes also showed different behaviors, which seems to be associated with different levels of seed dormancy.
