“…According to Koster and Leopold 1988;Leprince et al 1993;Black et al 1996;Brenac et al 1997, RFO are being accumulated in maturing seeds of many species, and there is a positive correlation between the level of these compounds and seed longevity (Bernal-Lugo and Leopold 1992;Bernal-Lugo and Leopold 1995). The ratio of seed sucrose/raffinose family oligosaccharides (S/RFO) seems particularly relevant.…”

Seeds of Lathyrus sativus cv. Derek and Krab were used as biological material for induced mutagenesis. Three mutant lines were obtained from seeds of grass pea cv. Derek and 15 lines from mutagenised seeds of cv. Krab. Twelve ethanol-soluble carbohydrates were identified in the seeds. We have selected grass pea mutant lines with high oligosaccharides content (lines D4, K56, K25, and K7) and lines with low raffinose family oligosaccharides (RFO) content (lines K12, K29 and K13). Mutations changing the levels of RFO have not affected the contents of galactosyl cyclitols.

“…Root tissue carbohydrates were extracted using a methodology adapted from Black et al [52]; 200 mg samples were homogenized in 1 mL of 80% (v/v) ethyl alcohol and incubated at 75 • C for 30 min, then centrifuged at 10,000 rpm for five minutes at 10 • C. This procedure was repeated two more times. After extraction, supernatants and precipitate were oven dried at 45 • C for 48 h. Residual supernatant was resuspended in 1 mL distilled water for TSS analysis.…”

Rosewood (Aniba rosaeodora Ducke) is an endangered tree that produces essential oil of high commercial value. However, technical-scientific knowledge about cultivation is scarce and studies are needed to examine the management viability. The current study evaluated rosewood aboveground biomass management, measuring the export of nutrients resulting from harvesting and testing sustainable management models. The crown of 36 rosewood trees were pruned and 108 trees cut at 50 cm above the soil in two regions in Central Amazonia. Post-harvest performance of sprouting shoots was evaluated and after, sprouting shoots were pruned so that the development of two, three and all shoots was permitted. Nutrient stock estimation was calculated as the product of mass and nutrient concentration, which allowed nutritional replacement to be estimated. The pruning facilitates regrowth by 40.11% of the initial mass while by cut regrow 1.45%. Chemical attributes of regrowth biomass differed significantly prior to management and regrowth had a significant correlation with the reserves in root tissues and with the pre -management status of the individual tree. Driving sprouts resulted in significantly larger growth increments and may provide a form of management that can viably be adopted. Biomass sequential management resulted in high nutrient exports and the amount of fertilizer needed for replenishment depended on the intensity and frequency of cropping. Compared with the cut of the tree, pruning the canopy reduces fertilizers that are required to replenish amount by 44%, decreasing to 26.37% in the second rotation. The generated knowledge contributes to this silvicultural practice as it becomes ecologically and economically viable.

Amaranthus caudatus L. seed germination was studied under different levels of water deficit induced by PEG 6000 in laboratory conditions. PEG at osmotic potentials -0.2 to -0.3 MPa at 24°C in darkness delayed germination and reduced final germination percentage. PEG solutions at osmotic potential lower than -0.3 MPa almost totally blocked seed germination. Ethephon was much more effective than GA 3 in reversing PEG-caused inhibition of A. caudatus seed germination. PEG decreased α-amylase activity after 14 h incubation. It decreased β-amylase activity after 14 and 20 h, and caused an increase in total dehydrogenase activity only after 20 h of incubation. Unlike GA 3 , ethephon increased α-amylase activity in seeds after 12 and 14 h of incubation under water deficit. After 20 h of incubation there was no difference in α-amylase activity in any of the treatments. Neither ethephon nor GA 3 affected the activity of β-amylase and dehydrogenase.K Ke ey y w wo or rd ds s: : Amaranthus caudatus seeds, α-, β-amylase, dehydrogenase, ethylene, gibberellin A 3 , polyethylene glycol.
