This study was carried out to determine the effect of different NaCl concentrations on germination and early seedling growth of some sugar maize (Zea mays L. sacharata sturt.) Varieties. NaCl was applied to the seeds of Vega F1 (sh2), Merit F1 (su) and Tanem F1 (su) varieties at 0 (control), 2, 4, 6, 8 and 10 dSm -1 concentrations. 5 days after seed sowing germination rate, 12 days after the root length, stem length, stem stem ratio, root dry matter ratio, stem dry matter ratio, seedling power index and salt tolerance were measured. Significant differences were found between the characters examined in the study. As a result; It was determined that germination rate and seedling growth characteristics decreased as cultivars salt ratio increased to different salt concentrations. It has been determined that while the total F1 cultivars have the highest values in terms of germination rate and salt stress tolerance, it has the lowest values in terms of root and stem length and root stem ratio. In terms of seedling power index, Vega F1, Tanem F1 and Merit F1, respectively. According to the correlation results, statistically significant positive differences were found between the parameters examined. It was determined that seed germination and early seedling growth parameters were not affected from the germination environment up to 2 dSm-1 salinity level, while it was found to be negatively affected at 2 dSm-1 high levels. It has been determined that water up to 2 dSm-1 salinity level can be used in sugar corn germination and early seedling development periods in aquaculture areas.

This study investigated the effects of potting media on seed germination and early seedling growth of Pterocarpus erinaceus Poir at the Forestry Nursery in Jos, Nigeria. Using Completely Randomized Design (CRD) with three replicates, laboratory-tested soil samples, top soil, sharp sand, sharp sand + top soil, sharp sand + top soil + cow dung and sharp sand + top soil + poultry droppings were used in various combinations to assess the growth parameters of P. erinaceus (germination percentage, emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Descriptive and inferential statistics were employed to analyze collected data. Result indicated that sharp sand + top soil + poultry droppings had the highest nitrogen concentration (2.19%), sharp sand + top soil + cow dung (2.07%), sharp sand + top soil (1.50%), top soil (0.72%) and Sharp sand (0.38%). Potting media with poultry droppings recorded an overall higher percentage germination of 42.9% by the end of the germination period. Analysis of variance (ANOVA) of collected data on combined soil aggregate on growth parameters indicated a significant (p<0.05) difference in plant height, number of leaves, leaf length and stem diameter. Potting with poultry dropping gave the best potting media growth results when compared to other treatments that enhanced seed germination and seedling growth of P. erinaceus. This superior observation of the poultry droppings incorporated potting mixtures over the cow dung provides an outstanding potentials to enhance P. erinaceus plantation establishment. Consequently, recommended for raising seedlings in the nursery as well as ensuring sustainable management.

<p>La calidad fisiológica de la semilla podría afectar el rendimiento de granos de arroz. Las diferencias en la calidad fisiológica de las semillas pueden causar la reducción y desuniformidad de la emergencia en el campo, acarreando una diferencia en el crecimiento inicial de las plantas, y consecuentemente afectando el cultivo y su rendimiento. Se realizo un experimento con el objetivo de evaluar la distribución espacial y la variabilidad en la población entre las plantas de arroz, en función de la calidad fisiológica de las semillas. Fueron utilizados nueve lotes de semillas de la cultivar BR-IRGA 410, siendo tres de alta, tres de media y tres de baja calidad fisiológica. Cada bloque consistió de nueve líneas de 5,5 metros de longitud, separadas por 0,12 metros. Se evaluó el número de fallas consecutivas y la variabilidad entre las plantas a través del coeficiente de variación de la altura de plantas y de la materia seca. El uso de las semillas con baja calidad fisiológica proporcionó mayor desuniformidad en la distribución espacial de la planta en el campo, y una mayor variabilidad entre las plantas que componen la población, lo que puede proporcionar un aumento en la competencia intra-especifica.</p><p align="center"><strong><em>Seeds physiological quality and variability among plants in populations of rice</em></strong><strong><em> </em></strong></p><p><strong>Abstract: </strong>Several authors try to relate the physiological quality of seeds with grain yield of rice. Differences in the physiological quality of seeds can cause reduction and uniformity of emergence in the field, leading to differential on early seedling growth, and consequently affecting the culture and your yield. An experiment was conducted to evaluate the spatial distribution and variability in populations of rice plants, depending on the physiological quality of seeds. Were used nine seed lots of cultivar BR-IRGA 410, three lots of high, three lots of medium and three lots of low physiological quality. Each block was composed of nine lines of 5.5 meters in length, spaced 0.12 meters. We evaluated the number of consecutive failures in emergence, and plant variability through the coefficient of variation of plant height and dry matter. The use of seed with low physiological quality provides increased uniformity in the spatial distribution of plants in the field, and greater variability from plants comprising the population, which can provide an increase in intra-specific competition.</p><p> </p>

The response of germination and early seedling growth to levels of salinity (0, 50, 100, 150, 200 and 250 mM NaCl) were examined in single seed lots of ten modern rice genotypes. Unaged and deteriorated rice seeds were germinated in rolled paper towels and in Petri dishes. Initial seed quality, final germination, germination rate and early seedling growth were assessed. The samples of the rice genotypes differed in their initial seed quality (measured in terms of Ki). The effect of deterioration varied depending upon the initial seed quality and the severity of the treatment imposed. Ageing (using the technique of controlled deterioration, CD) for up to 24 h had no effect on final germination levels. Although CD for 30 h only reduced final germination slightly, ageing for 36 or 48 h reduced it greatly. Controlled deterioration for 36 h or longer reduced the final length and the rate of extension of both the plumule and radicle. Combining information about germination in salt solution with that about seed quality enabled a distinction to be made between varieties which performed poorly because they were genetically salt-susceptible from those which germinated poorly due to poor seed quality. It is argued that the seed vigour of seed lots used in genotype evaluation should be assessed in order to avoid discarding potentially useful genotypes because of poor physiological seed quality.

The study was conducted at Dilla University, in the laboratory of Biological sciences to see the effects of salinity on germination and early seedling. Objectives:Background: It is estimated that the world 20% of farming land and 50% of cropland is salt stressed and salinity decreases the germination of seed, retards the growth of plant and so it reduces the yield of crop. Objectives: The major objective of this research was to evaluate the effects of salinity on the germination and early seedling growth of bean plants. Specifically, to investigate salt tolerant efficiency, salt effect on seed germination and its rate and growth of bean plant at different concentration of NaCl. Methodology: The experiment required 21 groups, of which 20 of them were experimental with different salt concentrations ranging from 0.05M to 1.00M with 0.05M difference and one control group. Each group contain three bean seed measuring its weight using electronic balance machine, sterilized with 70% Alcohol solution for 15 seconds, rinsed with distilled water, placed in separate Petri dish using a forceps, 50ml of solution were added to each Petri dish with different concentration, all Petri dishes were covered with lids and kept into incubator at room temperature for 17 days, germinated seed were counted, seedlings root and shoot length were measured using a ruler. Finally, the Bean was transferred to non-saline condition, weight of germinated Bean were measured to compare with their normal weight and to determine the effects of salt on seed weight, which was conducted in triplicates. All necessary data was taken, analyzed and interpreted in the form of percentage, graph, tables and figures. Result: When the concentration of salt increased the Bean plant is extremely affected, germination rate decreased and the terminal weights of seed were become lower than the initial weight due to the absorption of water by seed. Conclusions: The rate of germination decrease when the salt concentration increased and late growth of length of root and shoot when the salt dosage is highest and also the weights of seed reduced as concentration of salt is raised. Generally, as the concentration of salt is increased the Bean plant is extremely affected.

AbstractThe QTLs controlling germination and early seedling growth were mapped using seeds acquired from mapping population and parental lines of Chinese Spring and SQ1 grown under water-limited conditions, severe drought (SDr) and well-watered plants (C). Germination ability was determined by performing a standard germination test based on the quantification of the germination percentage (GP24) of seeds incubated for 24 h at 25°C in the dark. Early seedling growth was evaluated on the basis of the length of the root and leaf at the 6th day of the experiment. QTLs were identified by composite interval mapping method using Windows QTLCartographer 2.5 software. For the traits studied, a total of thirty eight additive QTLs were identified. Seventeen QTLs were mapped in C on chromosomes: 1A, 2A, 7A, 1B, 2B, 3B, 4B, 5B, 6B, 7B, 2D, 3D, 4D and 6D, while twenty one QTLs were identified in SDr on chromosomes: 1A, 2A, 5A, 2B, 3B, 4B, 5B, 6B, 7B, 3D, 5D and 6D. Most of the QTLs for GP and early leaf growth parameters were clustered on chromosome 4B (associated with the Rht-B1 marker) both in C and SDr plants. The results indicate the complex and polygenic nature of germination.

Salt stress is one of the most severe environmental factors that reduces and limits growth and development of plants. Abiotic stresses such as heavy metals, salinity, drought, temperature, UV-radiation, ozone causes drastic yield reduction in most of the crops. Especially salt stress affects around 20 of NaCl on germination and seedling growth of Zea mays L. Seeds of Zea mays were germinated in glass Petri- 100 × 15 mm diameter lined with blotting paper. Ten seeds were placed in each petri-dish. Petridishes were irrigated with 25, 50, 75, 100, 125, 150, 175 and 200 mM concentrations of NaCl. A control was moistened with ten milliliters of distilled water. The germination percentage, water absorption of the seeds, water uptake percentage and the growth parameters were observed. The results obtained showed that the inhibition of the germination percentage, germination rate, water uptake, growth and biomass accumulation of the seedlings were observed to decrease with increasing NaCl concentrations. At the highest level of stress both plumule and radical decreased significantly. The salt stress decreased seed germination, biomass and growth of maize seedlings due to ion toxicity, decrease osmotic potential and oxidative stress
