Summary. Wheat (Triticum aestivum L.) seed was grown at 2 locations differing in phosphorus (P) status (low and high) in north-eastern Victoria (36°S, 146°E), with applied superphosphate (kg P/ha: 0, 12, 24, 100 and 200), to produce seed of different P content. This seed was used in field and glasshouse experiments in 1993 and 1994 to investigate the effects of seed source and P content on the growth and yield of wheat. Wheat seed grown at the low P status site was smaller than seed grown at the high P status site, irrespective of the amount of applied P. Seed from the low P status site produced less early dry matter in both field and glasshouse experiments in 1993, but there was no effect of seed source on grain yield in either experiment. High seed P content either had no effect or reduced seedling emergence in the field experiments. In the glasshouse, low P content in seed from the low P status site resulted in reduced emergence. Increases in dry matter production and grain yield with higher seed P content were only observed in the drought season of 1994. Application of P resulted in increased emergence, dry matter production and grain yield at most seed P content levels but there were no significant interactions between seed P content and applied P. Application of N did not affect dry matter production in either year, but increased grain protein in both years and grain yield in 1993. Seed from low P status environments can affect early seedling growth but in average growing seasons, or in glasshouse conditions, wheat growth compensates so that differences in grain yield are not observed. However, in order to avoid risk of poor early seedling growth and possible yield penalties when the crop is stressed, wheat seed should be collected from adequate soil P status sites.

Identification of salt tolerant barley (Hordeum vulgare L.) genotypes and effects of different levels of salinity on their growth, grain development and yield were studied. One hundred and eighty nine barley germplasms were subjected in five levels of NaCl concentration which were equivalent to Electrical Conductivity (EC) of 0, 10, 15, 20 and 25 ds/m. Among the genotypes 39 proved to be saline tolerant at 15 ds/m of salinity. Out of 39 genotypes, 33 were evaluated at Sonagazi and Patuakhali salt area of Bangladesh. All the genotypes were evaluated in the non-saline area at BARI, Gazipur to observe their performance in normal soil. Highest grain yield was recorded from the genotypes BSH-32 and BSH-142 over the three locations. Significantly higher yield was recorded from the experimental site of Gazipur followed by Patuakhali and Sonagazi. Tiller per plant had positive correlation with grain per spike, maturity and grain yield. Grain per spike and maturity was positively correlated with grain yield. From the multivariate analysis it appears that 1st, 2nd and 3rd principal components together account for 79 per cent of the total experimental variation. The two selected genotypes are expected to be released for commercial cultivation in the saline area of Bangladesh.       Key words: Barley, Genotypes, Selection, Salt tolerant, Bangladesh DOI = 10.3329/bjb.v36i2.1504 Bangladesh J.

The response of BARI Sunflower-2 (Helianthus annuus L.) to sodium chloride (NaCl) at germination and early seedling growth was investigated. The seeds and seedlings of sunflower were treated with a series of eight different concentrations of NaCl viz 25, 50, 75, 100, 125, 150, 175 and 200 mM and distilled water (control) and were allowed to grow under plate culture condition. The results showed that the highest salinity concentration (200 mM NaCl) remarkably decreased the germination percentage, germination index and speed of germination of BARI Sunflower-2. Fresh and dry masses of both shoot and root were significantly reduced at a 25-200 mM NaCl solution. Significant reductions of shoot and root length were also noted with the increase of NaCl concentration. The results also illustrate that up to 50 mM NaCl concentration, all of the germination indices and fresh and dry biomass were withstand more than 70%. Thus the present study concluded that the BARI Sunflower-2 could be cultivated in moderately saline soil.Jahangirnagar University J. Biol. Sci. 7(1): 35-44, 2018 (June)

AbstractThis study was performed to assess several indices for identifying genotypes at germination stage with the best performance in salinity conditions. In order to evaluate the seed germination of barley genotypes in different levels of salt conditions, an experiment was conducted as factorial arrangement with a completely randomized design with 3 replications. The effect of salinity treatments was studied through an analysis of the germination, yielding results that show significant differences among genotypes. Stress tolerance index, stress tolerance, stress susceptibility index, germination reduction ratio, mean productivity and geometric mean productivity were used. The majority of used indices indicated that ESBYTM8910, 4 Shori and MBS8715 were the best barley genotypes showing the highest stress resistance for the greatest NaCl concentration. This result was similar to those obtained from the analysis of variance and statistical comparison of means of genotypes germination percentages. There were positive and strong correlations of germination percentage in normal and stress condition with STI in high levels of salinity. Thus, this correlation seems to be a useful indicator of tolerant genotypes at this stage.

Germination Experiment

An incubation experiment was conducted at the Department of Soil Science, Patuakhali Science and Technology University during Rabi season 2015 to investigate the effects of different levels of salinity on germination and early seedling growth of maize. There were ten treatments consisting of different concentrations of salinity viz. 0, 20, 40, 80, 120, 160, 200, 240, 280 and 320 mM NaCl. The germination experiment was conducted in petri dish lined with a layer of cotton consisting ten ml of each test solution. Germination percentage gradually decreased with the increase of concentration of salt. Up to 80 mM concentration was found safe for maize seed germination. Salinity caused delay in germination.  Highest seedling height was found at 40 mM NaCl concentration (21.51 cm) and root length (23.61 cm) was found in 20 mM NaCl concentration. In 320 mM NaCl concentration roots were abnormal, deformed and twisted. The 0 to 80 mM NaCl concentration gave statistically similar shoot fresh weight. Compared to control treatment 20 mM NaCl concentration gave 0.55 % higher fresh weight and at 80 mM NaCl concentration shoot fresh weight reduced by only 6.9 %. The 80 mM NaCl concentration was found acceptable for germination and early seedling growth of maize.Progressive Agriculture 28 (1): 18-25, 2017

The present study was carried out to evaluate the response of different bioagents/biofungicides and growth regulators on seed germination and early seedling growth of sunflower. Eleven (11) treatments were established for the present investigation. Higher germination was observed in T5, T6/T7, T10 and T11 treatments in contrast to other treatments. Treatments T7, T3 and T11 were found significantly better than all other treatments. Generally, root and shoot length increased with the advancement of growth stages. T4 showed higher number of secondary roots in comparison to all other treatments. The shoot length and root length in all the cases (irrespective of the cultivars: DRSH-1, DRSF-108, LSFH-171) were highly influenced by the bioinoculants and chemicals; however, influence of bioagents was found better than the chemicals. Similarly, the seedling weight in 96 hours after sowing and 144 hours after sowing in all the cultivars was reported higher than when the seeds were treated with bioinoculants, which reflected the efficacy of the bioinoculants compared to others.
