External applications of strigolactones affect plant growth positively owing to the potential adapting plants tolerance system under stress conditions. In this study, effect synthetic analogue strigolactone (GR24) pre-treatment seeds salt-tolerant and salt-sensitive bread wheat (Triticum aestivum L.) varieties on parameters, antioxidant enzymes, such as superoxide dismutase (SOD), ascorbate per...

Four ecotypes of the species Lycopersicon cheesmanii ssp. minor (Hook.) C.H. Mull. from the Galapagos Islands were compared with L. esculentum Mill cv. VF 36 with respect to salt tolerance. The L. cheesmanii ecotype that proved most salt-tolerant was selected for detailed comparison with the L. esculentum cultivar. Plants were grown in modified Hoagland solution salinized with synthetic seawate...

In order to assess relationship between ion transport and variation in growth responses of four canola cultivars under salt stress, four canola cultivars were grown at 0 and 150 mM NaCl for six weeks in hydroponics. Salt stress reduced the shoot and root fresh and dry weights of all canola cultivars. Maximum shoot fresh and dry weights were recorded in Dunkeld under both non-saline and saline c...

Salt produces free radicals in the plants and these free radicals are scavenged by the antioxidative capacity of the plant. Change in antioxidant activity, phenolic contents, lipid peroxidation, glycine betaine and proline contents were investigated in fifteen genotypes of wheat differing in salt tolerance. The results revealed that the aqueous extracts of wheat (300 μg/ml) in control and under...

Spontaneous mutants of Rhizobium leguminosarum biovar viciae strain C1204b were selected for their ability to tolerate 0.2 M NaCl, a growth-inhibiting level of salt for the parental strain. Transposon-mediated salt-sensitive mutants of strain C1204b were screened for their inability to grow in 0.08 M NaCl. Quantitation of the free-amino acid pools in the mutants grown in NaCl revealed a dramati...

Delay tolerant networks (DTNs) are networks whose nodes have low connectivity and/or unreliable links. Because of these characteristics, DTN nodes use a store-carry-and-forward technique to deliver data through the network. Communication over DTN relies on intermediate nodes sharing their resources and can be abused by resource hogs, i.e. individuals who generate messages at a rate that is much...

Present day Internet conventions show wasteful execution in those systems .where the availability between end hubs has discontinuous property because of element topology or asset imperatives. System situations where the hubs are described by operation opportunistic availability are alluded to as Delay Tolerant Networks (DTNs). Exceedingly usable in various pragmatic applications, for example, l...

In a Delay Tolerant Network (DTN), routing protocols are developed to manage the disconnected mobile nodes. We propose a routing protocol named HALF (Handoff-based And Limited Flooding) in DTN that can work in both infra-structured and infra-structure less networking environment and hence it can improve the performance of the network significantly. In this paper, it is shown that HALF gives sat...
