This study was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) under controlled environmental conditions of greenhouse to determine the effects of different concentration of sodium chloride (NaCl) on germination and seedling growth of Phaseolus vulgaris L. Five concentrations of sodium chloride (o mol(distilled water), 0.1M, 0.2M,0.3M and 0.4M) with one control treatment of un-primed seeds were laid out  in completely randomized design (CRD) with three replication. Data were collected on standard germination, Rate of germination, Seedling height, Shoot length, Root length and Vigor index. The result revealed that different NaCl concentrations statistically (p≤0.05) affected standard germination, Rate of germination, Seedling height, Shoot length and Vigor index I of common bean crop. The highest value of all these parameters were obtained from seed primed with 0.1M NaCl as well as when the seed primed with distilled water. However, the lowest values of these parameters were recorded on the seed primed with the highest concentration (0.4M) of NaCl and un-primed seed. More of the examined parameters were decreased with increasing of NaCl concentration. In conclusion, priming seed with 0.1M of NaCl concentration enhanced germination and seedling performance of common bean.

In this study, the effect of five different levels of salt (NaCl) on the germination of Phaseolus vulgaris L. seed was investigated. Laboratory experiment with completely randomized design comprising three replicates in Petri dishes was conducted at Gaziantep University Vocational School of Higher Education in Nurdagi to determine the salt effects on common bean germination. The germination of the cultivar (Tegmen) was studied using distilled water (control) and under osmotic potential of 0.3, 0.6, 0.9, 1.2, and 1.5 MPa NaCl. The results indicated that the Mean germination time (MGT), Germination index (GI), Coefficient of velocity of germination (CVG), Germination percentage (GP), and Seed vigor index (SVI) varied between 3.13 and 3.78 days, 6.88 and 3.93, 0.156 and 0.153, 90 and 60%, and 867.0 and 290.3, respectively. Significant differences were found among NaCl treatments in terms of GI, GP, and SVI. All the examined parameters were decreased with increasing NaCl concentration, except MGT. The max and min GI, GP, CVG, and SVI were observed at the control condition (0.0 MPa) and highest osmotic potential (1.5 MPa) of NaCl, respectively. Correlation coefficient between all possible combinations was estimated and the results indicated that MGT, GI, GP, CVG, and SVI had significant positive or negative correlation with each other.

Acid-scarified hogpotato (Hoffmanseggia densifloraBenth. ex. Gray # HOFDE) seed incubated in distilled water germinated at least 94% when incubated at constant 15, 20, 30 C, and at alternate 20/30 C (20 C for 16 h and 30 C for 8 h) temperatures. Highest germination in buffered solutions occurred at pH 5.0 and 6.0 with reduced germination at lower and higher pH levels. Sodium chloride concentrations of 50 mM and greater reduced the germination rate. Percent germination after 9 days was reduced at NaCl concentrations of 100 mM and greater. Radicle lengths measured after 3 days were significantly reduced with increasing NaCl concentration. Twenty-day-old hogpotato seedlings having three true leaves were able to resprout after topgrowth removal. Regrowth occurred on 15% of the seedlings approximately 15 days after top removal.

Seed germination of diverse common bean (Phaseolus vulgaris L.) genotypes was evaluated under controlled suboptimal conditions. Initially, 16 genotypes were tested at 12 and 16 °C. A subset of genotypes was subsequently germinated in distilled water or in polyethylene glycol solutions with water potentials (WP) of either −0.4 or −0.8 MPa at temperatures of 22, 26 or 34 °C. Genotypes did not respond consistently to low temperature stress, as indicated by significant (P < 0.05) crossovers in genotype ranking for percent germination from one temperature (12 °C) to the next (16 °C). Genotypes differed in median germination time (GT50) and estimated maximum germination rate. Genotypes with thinner seeds germinated better than wide-seeded genotypes under low-temperature conditions. Seed germination was reduced by 10 percentage units at a WP of −0.4 MPa and was virtually nil at a WP of −0.8 MPa. GT50 was reduced by 30% at 26 versus 22 °C but delayed by 80% when the WP was lowered from 0 to −0.4 MPa. Similarly, maximum germination rate increased with temperature but decreased with WP. Based on the germplasm evaluated in this study, common bean genotypes differ in seed germination response to temperature and moisture stress. Key words: Common bean, Phaseolus vulgaris L., germination, temperature, water potential

The common bean (Phaseolus vulgaris L.) is one of the main legumes produced and consumed in the Central African Republic (CAR). But in CAR, the common bean production is constrained by certain biotic and abiotic stress which severely impacts the quantity and quality available in the value chain. To compensate this loss of the production, the Central African Institute for Agronomic Research (ICRA) had introduced in CAR ten varieties of common bean from Rwanda and Cameroon. A four-repeat randomized full-block device was used for testing the performances of these ten varieties of common bean. The measured variables were the vegetative growth, the production, and the sensibility to plant diseases. Overall, the different varieties exhibited a high germination rate (88.6%). The highest rate is observed in variety RWR2245 from Rwanda (100%). Varieties from Rwanda, RWR3194 with 1000 kg ha-1 and BOA5M1-6 with 916.66 kg ha-1 gave better yields followed by varieties Ecapan 025 from Cameroon with 833.33 kg ha-1 and RWR2245 with 833.33 kg ha-1. The yields obtained are roughly referred to the agronomical standard. The varieties NITOU and NUA566 from Rwanda were more susceptible to disease incidence and pest attacks compared to those from Cameroon.
