“…Seeds of Tabebuia caraiba (Mart.) kept in paper packaging and stored at laboratory conditions have lost more quickly their vigor along the storage period (Guedes, Alves, Melo, Moura & Silva, 2012). The reduction of seed vigor during storage was also observed in this study for R. laxiflora, with reduced germination parameters after one year of storage.…”

Germination of diaspores and the seedling structure of Ruprechtia laxiflora Meissn. (Polygonaceae) which is a secondary species frequent in forest remnants are described. Seedlings were embedded in hydroxymethacrylate and sectioned in a rotary microtome according to usual techniques in plant anatomy. For bioassays of germination, the experimental design was completely randomized in a 3x2 bifactorial arrangement, corresponding to three temperatures (20, 25 and 30°C) and two light conditions (photoperiod and continuous darkness) for the diaspores newly harvested and in a 4x2 bifactorial arrangement, corresponding to four temperatures (15, 20, 25 and 30°C) and two light conditions (photoperiod and continuous darkness) for diaspores analyzed after storage. There was no interaction between the factors light condition and temperature for germination parameters analyzed. However, the temperature affected the germination and diaspores maintained at 25°C showed a shorter mean time and higher germination speed index. Seedlings are phanerocotylar and epigeal with tetrarch root, intermediate-low type of root-stem transition and trilacunar cotyledonary node.

“…This fact was more evident after 180 days, whose reductions were 22% and 28% for seeds from natural and climate-controlled environments, respectively (Figure 1A). Unlike the seeds of Tabebuia caraiba Mart., germination significantly decreased during storage in a natural environment, with total loss of vigor after 90 days (Guedes et al, 2012). According to these authors, the rapid loss of seed vigor was due to the increase in water content during storage, a fact that was not verified for "mofumbo" seeds.…”

Physiological and biochemical responses of “mofumbo” seeds during storage

“Mofumbo” (Combretum leprosum Mart. (Combretaceae) is a neotropical species of wood, pharmacological, beekeeping and environmental importance. Thus, the objective was to evaluate the biochemical and physiological responses in C. leprosum seeds under different storage environments. The experiment was carried out in a factorial (2 x 7), with two storage conditions (natural and climate-controlled environments) and seven storage periods (0; 60; 120; 180; 240; 300 and 360 days), in four replications per treatment. At the beginning of storage and at 60-day intervals, the seeds were analyzed for water content, physiological potential (germination, germination speed index, root and shoot lengths and seedling dry mass) and biochemical (neutral lipids, lipid peroxidation, total and reducing sugars, total free amino acids, and starch). The results indicated that storing “mofumbo” seeds for 360 days reduced viability, being more pronounced after 180 days, regardless of the storage environment. “Mofumbo” seeds were stored in a natural environment for 180 days, resulting in less lipid degradation. After this period, the reduction was associated with the attack of reducing sugars on amino acids. Thus, it is concluded that “mofumbo” seeds must be stored in a natural environment for up to 180 days.

“…The observed results indicate that storage for 12 months in an environment without temperature control (mean of 24 °C) enhances the process of deterioration of M. caesalpiniifolia seeds. Storage at room temperature also promoted faster loss of viability of Caesalpinia echinata seeds, at three months (Hellman et al, 2006), Tabebuia caraiba seeds, at three months (Guedes et al, 2012b), Myracrodruon urundeuva seeds, at 150 days (Guedes et al, 2012a) and Melanoxylon brauna seeds, at 24 months (Freire et al, 2021), compared to colder temperatures.…”

The maintenance of seed viability during storage is influenced by several factors related to the species and to the environment. This work aimed to determine the viability of Mimosa caesalpiniifolia seeds from unripe and ripe fruits stored at different temperatures (ambient, 10 ºC, 0 ºC and -21 ºC). For this, the germination performance of the seeds was evaluated at 0, 3, 6 and 12 months of storage. The experimental design was completely randomized, with four replicates of 25 seeds per treatment. The variables evaluated were: number of germinated seeds, number of hard seeds, number of unviable seeds and number of normal seedlings. The storage potential of M. caesalpiniifolia seeds depends on the fruit maturity stage. Seeds from unripe fruits without drying do not tolerate storage. Seeds from unripe fruits with drying at 15% water content maintain viability, for 12 months, when stored at a temperature of 10 °C. Seeds from ripe fruits without drying maintain viability, for 12 months, when stored at temperatures of 0 °C and 10 °C.
