The biocontrol agent, Cladosporium cladosporioides, strain BOU1 was used to evaluate the rice and wheat plant growth by germination percentage, germination index, vigor index- I and vigor index-II in rice and wheat seed. All the variables of germination and seedling vigor of rice and wheat were increased by the conidial suspension of C. cladosporioides. The rice seed treated with C. cladosporioides had the highest germination index and vigor index-I with average mean values of 8.2 and 4.5, respectively; while the treated wheat seed showed the highest germination percentage and vigor index- II with average mean values of 80.3 and 0.05, respectively. The research is concluded that the biocontrol agent C. cladosporioides improves seed germination and seedling vigor of wheat and rice, which can finally be converted into superior yield even in adverse conditions.

Sorghum is one of the world’s most important food, feed, and fiber crops as well as a potential feedstock for lignocellulosic bioenergy. Early-season planting extends sorghum’s growing season and increases yield in temperate regions. However, sorghum’s sensitivity to low soil temperatures adversely impacts seed germination. In this study, we evaluated the 242 accessions of the ICRISAT sorghum mini core collection for seed germination and seedling vigor at 12 °C as a measure of cold tolerance. Genome-wide association analysis was performed with approximately 162 177 single nucleotide polymorphism markers. Only one marker locus (Locus 7-2) was significantly associated with low-temperature germination and none with vigor. The linkage of Locus 7-2 to low-temperature germination was supported by four lines of evidence: strong association in three independent experiments, co-localization with previously mapped cold tolerance quantitative trait loci (QTL) in sorghum, a candidate gene that increases cold tolerance and germination rate when its wheat homolog is overexpressed in tobacco, and its syntenic region in rice co-localized with two cold tolerance QTL in rice. This locus may be useful in developing tools for molecular breeding of sorghums with improved low-temperature germinability.

Studies were conducted to determine the growth, fecundity, and competitive ability of an acetyl-CoA carboxylase (ACCase)–inhibitor resistant (R) sterile wild oat biotype compared with a susceptible (S) biotype. Seed germination studies indicated that there were no differences in seed germination and seedling vigor between R and S biotypes at any temperature regime. R and S biotypes were grown under noncompetitive and competitive arrangement in the greenhouse. Under noncompetitive greenhouse conditions, growth of the R biotype was similar to that of the S biotype on the basis of plant height, canopy area, and plant biomass. Seed production and weight of R and S plants were also at the same levels. Furthermore, relative competitiveness among the R and S sterile wild oat biotypes was investigated by means of replacement series experiments. The R and S biotypes were compared under seven mixture proportions (6 : 0, 5 : 1, 4 : 2, 3 : 3, 2 : 4, 1 : 5, and 0 : 6). No significant differences in competitive ability were observed between R and S biotypes on the basis of plant height, canopy area, or plant biomass. In most cases, relative crowding coefficient (RCC) values at 20, 60, and 100 d after transplanting (DAT) were close to one, indicating equal competitiveness between the R and S biotypes of wild oat used in this competitive study. However, in some cases, the RCC value was 1.31 for plant height, evident of a slight competitive advantage for the R biotype at 100 DAT. In general, ACCase-inhibitor R and S sterile wild oat biotypes were equally competitive, clearly without any growth penalty for R plants in either noncompetitive or competitive conditions.

Bacterial Strains

The potential of antagonistic bacteria from paddy water, rhizosphere soils, sclerotia, and rice plants to control “bakanae” caused by Fusarium moniliforme was assessed. Experiments were conducted to determine the in vitro antibiosis and effect of bacteria on seed germination. Out of 441 isolates, 113 were inhibitory to mycelial growth of the pathogen. Bacterial strains were classified into three groups based on effect on seed germination: (i) those that promoted germination and enhanced seedling vigor; (ii) those that had no effect on germination; and (iii) those that were deleterious and inhibited germination. Bacterization of naturally infected seeds reduced bakanae incidence in seedbox and seedbed tests. In a seedbed experiment with IR 58 seeds soaked in suspensions of bacterial strains, bakanae incidence and disease control ranged from 0.9 to 6.8% and 71.7 to 96.3%, respectively. From the 3 years of field trials, 10 strains reduced bakanae. Five strains consistently reduced bakanae, but the other five exhibited variable effects among trials. Specificity of suppression by antagonistic bacteria against different pathogenic isolates of F. moniliforme from various locations in the Philippines was observed.

The Impact

Seed size may influence seed germination, and seedling vigor. Few investigations are available about the effect of seed size on barley seedling vigor in Jordan. The present study was designed to investigate the impact of seed size on germination percentage, seedling dry weight, seedling vigor index, and germination percentage after accelerated aging in barley. Three seed sizes i.e. large, medium, and small (having diameter of > 2.75 millimeter, 2.5 - 2.75 millimeter, and less than 2.5 millimeter, respectively) were tested in the experiment. Seed quality for different seed size categories was evaluated in the laboratory by measuring seed germination, germination after accelerated aging, as well seedling dry weight and vigor index. Results showed significant differences for large seeds in germination percentages, seedling dry weight and vigor index. It may be concluded that large seed size of barley showed best quality.
