Seed Germination and Reserve Mobilization
Germination incorporates events that commence with the uptake of water (imbibition) by the quiescent dry seed and terminates with the emergence of the embryonic axis, usually the radicle. It is a time of intensemetabolic activity, involving subcellular structural changes, respiration, macromolecular syntheses and, finally, cell elongation. Establishment of the seedling occurs following germinat...
متن کاملHygroscopic Behavior of Lyophilized Powder of Grugru Palm (Acrocomia aculeata)
The objective of this study was to determine adsorption isotherms and hygroscopic behavior of lyophilized powder from grugru palm. The powders of grugru palm were obtained by lyophilization process without maltodextrin (T1) and with 8% matodextrin (T2). The experimental data were obtained through the static gravimetric method at temperatures (25 ̊C, 30 ̊C, 35 ̊C and 40 ̊C), with different saturated...
متن کاملCultivated Palm Seed Germination
The propagation of palms for agricultural and ornamental purposes is accomplished typically by seeds. The few exceptions are certain cultivars of Phoenix dactylifera and some ornamental palms such as Rhapis spp., which propagate by vegetative (division) and tissue culture. Because of slow, irregular germination in most species, seed propagation may be a challenge. New palm species are being int...
متن کاملProtein mobilization and proteolytic enzyme activities during seed germination of broad bean (Vicia faba L.).
The protein mobilization from attached and detached seeds of Vicia faba L. cv. Eresen 87 (Fabaceae) was investigated. While the total soluble protein content decreased, the free amino acid content increased during the 7 days germination period. Among the three proteolytic enzymes, only endopeptidase activity was found to be affected by the removal of the embryonic axis. Leucine aminopeptidase a...
متن کاملAnatomy, histochemistry and ultrastructure of seed and somatic embryo of Acrocomia aculeata (Arecaceae)
Macaw palm (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) is a tropical species with multiple uses, including oil supply for biodiesel production. However, structural and physiological studies of the seed are still scarce, as well as in vitro propagation techniques. The aim of this study was to characterize the anatomy, histochemistry and ultrastructure of the seed and the in vitro somatic embryo ...
