The aim of this study was to investigate the effects of different temperatures, light regimes, and seed moisture contents on germination of the palm Euterpe precatoria, in the Arecaceae family. For the study of light and temperature, the experimental design was entirely randomized; treatments were arranged in a 6 × 2 factorial scheme [six temperature conditions (20˚C, 25˚C, 30˚C, 35˚C, 20˚C -30˚C, and 25˚C -35˚C) combined with two light regimes (light and darkness)] with four replications composed of 25 seeds each. For the seed moisture content study, the experimental design was entirely randomized with five seed moisture contents (27%, 20%, 13%, 12%, and 11%), to which they comprised 5 treatments, and four replications with 25 seeds each. Number of germinated seeds was recorded daily until germination was steady. Data were submitted to variance analysis; for the first experiment, means were compared by the Tukey test (p ≤ 0.05) and, for the second, the regression analysis was performed. The temperature at 20˚C promoted highest germination percentage and germination rate for E. precatoria seeds, under either light or darkness; seeds were tolerant up to 11% moisture content.

“…In general, mature palm seeds exhibit the best overall germination performance (Rauch et al, 1982;Broschat and Donselman, 1987;Broschat, 1994;Maciel de Sousa, 1995;Silva et al, 1999). However, in some species, germination rates are higher for pre-mature seeds, but the overall germination percentages were superior once the seeds were mature (Broschat and Donselman, 1987;Maciel, 2001).…”

Seed behaviour in Phoenix reclinata Jacquin, the wild date palm

Despite the importance of the palm family, Arecaceae, little has been systematically documented about the seed behaviour of the many species. The post-harvest seed behaviour of Phoenix reclinata, the highly utilized wild date palm species distributed along the eastern seaboard of Africa, is investigated in the present study. While both embryo and endosperm water concentration declined as the seeds of Phoenix reclinata matured, they remained relatively high: this is a characteristic of (but not confined to) non-orthodox seeds. The ultrastructure of embryo cells, and the finding that negligible water uptake was required for the initiation of germination, were in keeping with the possible non-orthodox nature of the seeds. A developmental study revealed that between the acquisition of full germinability and complete preshedding maturity, germination performance appeared to be constrained, suggesting the presence of an inhibitor. Pre-treatment by soaking, mechanical or acid scarification had no significant promotory effect on either rate or totality of germination of mature P. reclinata seeds, while use of water transiently at 100°C was highly deleterious. However, germination of partially dehydrated seeds was initiated sooner if they had been soaked or scarified. Mature P. reclinata seeds tolerated dehydration to a mean embryo water concentration of 0.40 g g ‫1מ‬ (dry mass basis; dmb), but at 0.14 g g ‫1מ‬ , both rate and totality of germination were adversely affected. However, viability of seeds dehydrated to the mean embryo water concentration 0.40 g g ‫1מ‬ declined during storage for 16 weeks. It is concluded that P. reclinata seeds are nonorthodox, and are best categorized as showing intermediate post-harvest behaviour.

“…Light not only affects the synthesis of anthocyanins, but also the synthesis of cutin and wax, and the maturation of purple maize ( Silva et al, 1999 ; Giovannoni, 2001 ; Li et al., 2007 ; Lee and Suh, 2013 ). In this study, the transcriptome of purple waxy maize kernels was altered seriously by light at 17 DAP.…”

IntroductionWaxy maize, mainly consumed at the immature stage, is a staple and vegetable food in Asia. The pigmentation in the kernel of purple waxy maize enhances its nutritional and market values. Light, a critical environmental factor, affects anthocyanin biosynthesis and results in pigmentation in different parts of plants, including in the kernel. SWL502 is a light-sensitive waxy maize inbred line with purple kernel color, but the regulatory mechanism of pigmentation in the kernel resulting in purple color is still unknown.MethodsIn this study, cyanidin, peonidin, and pelargonidin were identified as the main anthocyanin components in SWL502, evaluated by the ultra-performance liquid chromatography (UPLC) method. Investigation of pigment accumulation in the kernel of SWL502 was performed at 12, 17, and 22 days after pollination (DAP) under both dark and light treatment conditions via transcriptome and metabolome analyses.ResultsDark treatment affected genes and metabolites associated with metabolic pathways of amino acid, carbohydrate, lipid, and galactose, biosynthesis of phenylpropanoid and terpenoid backbone, and ABC transporters. The expression of anthocyanin biosynthesis genes, such as 4CL2, CHS, F3H, and UGT, was reduced under dark treatment. Dynamic changes were identified in genes and metabolites by time-series analysis. The genes and metabolites involved in photosynthesis and purine metabolism were altered in light treatment, and the expression of genes and metabolites associated with carotenoid biosynthesis, sphingolipid metabolism, MAPK signaling pathway, and plant hormone signal transduction pathway were induced by dark treatment. Light treatment increased the expression level of major transcription factors such as LRL1, myc7, bHLH125, PIF1, BH093, PIL5, MYBS1, and BH074 in purple waxy maize kernels, while dark treatment greatly promoted the expression level of transcription factors RVE6, MYB4, MY1R1, and MYB145.DiscussionThis study is the first report to investigate the effects of light on waxy maize kernel pigmentation and the underlying mechanism at both transcriptome and metabolome levels, and the results from this study are valuable for future research to better understand the effects of light on the regulation of plant growth.
