The objective of the study was to find the effects of NaCl stress at electrical conductivities of 4.5, 8.6, 12.7 and 16.3 dS/m and seed sizes （7, 8 and 9 mm） on germination and early seedling growth of three popular chickpea cultivars （AKN-97, Gokce and Uzunlu-99）. Mean frequency of germination, germination time, germination index, root length, shoot length and seedling fresh weight showed seed size-dependent responses ofcultivars to salt stress. In general, small seeds germinated and grew more rapidly compared to medium and large seeds of the same cultivars against all levels of salt stress, with the best results in cultivar Uzunlu-99. No effect of NaCl treatments was observed on frequency of germination; however, a drastic decrease in early seedling growth was recorded at increased NaC1 concentrations. Regression analysis results showed a significantly positive relationship （P〈0.01） between seed size and mean germination time, whereas a significantly negative relationship was recorded between seed size and germination index, root length, shoot length. Moreover, linear regression values apparently confirmed that increased seed size in each cultivar affected decreased germination index, root and shoot lengths with enhanced mean germination time. Thus, it was concluded that the use of small seeds could considerably reduce the production costs of chickpea in salt-affected soils.展开更多

Chickpea, grown under irrigation regime (30 + 30 mm of water) and fertilized with 50 kg·N·ha-1 before planting and with 40 kg·N·ha-1 at blossom growth stage, produced more total dry biomass and seed yield as compared with that grown under non-irrigated conditions and fertilized with 50 kg·N·ha-1 before planting only. In particular, irrigation and nitrogen fertilization at blossom growth stage increased total dry weight of chickpea by 18.3% and 18.5%, respectively, as compared with that of non-irrigated and fertilized with N before planting. The corresponding increase of seed yield was 30.5% and 20%, respectively. The total dry biomass of “Amorgos” was 10% and 13% greater than that of “Serifos” and “Andros”, while its respective seed yield increase was 5% and 16%. Finally, the quantum yield of photosystem II of chickpea was not affected by irrigation or fertilization. These results indicated that nitrogen fertilization at blossom growth stage combined with irrigation increased seed yield of all chickpea varieties, whereas the same treatments did not have any effect on plant quantum yield of photosystem II.展开更多

The data revealed that moisture and arnylose content of uncooked mungbean varieties ranged 9.01-9.47% and 20.06-22.26% respectively. The moisture and amylose content of Kabuli type chickpea varieties varied 8.52-8.79% and 20.25-22.83% respectively. Moisture content of mungbean （64.16-66.08%） as well as chickpea （55.56-61.52%） varieties increased after cooking. For all the three varieties of mungbean the observed cooking time was 11 minutes. The maximum value of amylose content was assayed for NM-98 （20.74%） followed by Ramzan （20.24%）. The cooking time of Kabuli type chickpea varieties CMNK-452-2 and CMNK-10-99 was 60 min. Hassan 2K observed more cooking time （90 min） and highest value of amylose content in cooked （19.01%） samples. The effect of cooking/varietals on sensory evaluation （appearance, flavor, texture and overall acceptability） of mungbean varieties was statistically non significant attributes. Among chickpea varieties, Hassan 2K was ranked lowest due to its small size and hard texture and the sensory attributes were statistically significant （P 〈 0.05） as compared to the other two varieties.展开更多

The best strain is obtained in temperature of 20℃(ambient). According to the results of the rhizogenesis, we notice that the nutrient agar (NA) medium responds better that the PDA medium for Cicer arietinum. Meanwhile, the medium PDA brings a better reaction (response) compared with the nutrient agar medium concerning Pisum sativum.展开更多
