Plants respond to salinity in two distinct phases: a quick osmotic phase and a sluggish ionic phase also known as hyper osmotic phase. Plants adjustment and/or tolerance to salinity stress comprise several complex physiological, biochemical and molecular networks. A widespread understanding of how plants response to salinity stress at different phases, and a cohesive physiological and biochemical approaches are crucial for the development of salt adapted and/or tolerant varieties for salt-affected areas. Researchers have identified several adaptive responses to salinity stress at cellular, biochemical and physiological levels, even though mechanisms triggering salt stress adaptation and/or tolerance are far from being entirely understood. This article bestows a spacious review of foremost research advances on physiological and biochemical mechanisms governing plant adaptation and/or tolerance to salinity stress relevant to environmental sustainability and as well as food production.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74159571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three sites representing three different elevations viz. highland, midland and lowland agroecology were selected. A total of 196 households were randomly selected to collect socioeconomic data. Data on woody species diversity in crop fields was collected by categorizing households as rich, medium and poor and from that categorized household the woody species data were collected from near, medium and far away from homesteads. A total of 39 woody species belonging to 24 families were recorded in the farmlands of the study area. The Shannon diversity index varied from 2.61 to 2.85 and species evenness varied from 0.83 to 0.87 in the study areas. Woody species diversity, richness and abundance were significantly different between rich, medium and poor households at the three study sites. Similarly species richness, abundance and diversity were significantly different among near, medium and far distance farmlands from homesteads. According to the respondents, the main purposes of retaining or planting woody species on their farmland were for soil fertility (35.14%), firewood (24.54%), timber production (11.66%), fencing (8.44%), animal fodder (4.55%), fruit (4.50%), income generation (4.28%), house construction (2.61%), charcoal production (1.61%) and other purposes. Retaining or planting woody species on farmlands significantly contributed for the conservation of biodiversity in the study area.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76394421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The genetic parameters for seed germination and other associated parameters showed a wide range of variations in progenies of different candidate plus trees (CPTs) at nursery stage except collar diameter. The CPTs, BHB-1 and BHB-2 invariably exhibited high germination and other parameters, whereas GK-1 recorded with the least performer with respect to germination, shoot and root vigour index. Analysis of variance indicated significant variation existed among the CPTs of different localities for all the traits under study. Considering genetic advance and heritability, the highest genetic gain obtained for germination, seedling height, shoot vigour index, root vigour index suggested these traits effective means for selection of CPTs. Highest 100 seed weight was recorded with CPT BHB-3 which was on par with other CPTs (BHB-1, BHB-2 and BHB-4) of the same locality.

The increase in urbanization and associated vehicular movement had increased the heavy metal influx in the ambient air of Himalayan ecosystems. Bioindicators such as lichens due to their slow growth, longer lifespan and maximum absorption of nutrients through atmospheric deposition, can be used as an appropriate indicator of long-term heavy metal deposition in the Himalaya. In the current study, a terricolous lichen Stereocaulon foliolosum was studied in the temperate habitat of Munsyari, Pithoragarh district, Uttarakhand, central Himalaya, for its ability as a bioindicator of ambient air heavy metal deposition along with land use linked vehicular exhaust gradient. In the current study, Stereocaulon foliolosum was analyzed for lichen diversity and seven heavy metals(Mg, Zn, Cu, Pb, Mn, Ni, Cd) deposition in five plots in Khaliya bugyal-Munsyari landscape along gradients of land use and elevation. The maximum heavy metal deposition was recorded in plots along roads which minimized in Khaliya bugyal. The total heavy metal load (ΣM7) was found indicative of land use gradient followed by Mg, Zn, Cu and Ni accumulation in lichen thallus. The study concluded that the diversity of Stereocaulon foliolosum was negatively correlated to the vehicular density which was maximum at moderate elevations exhibiting intense land use and maximum vehicular movement. The study thus established that change in lichen diversity can be an appropriate indicator of land use linked pollution gradients in temperate habitat in Kumaun, central Himalaya.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88733036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notable differences were observed in case of Zn, Cu, Mn and Fe content within and across mango orchards. Histogram distribution showed Zn and Cu content in the maximum frequency range of 0.5 to 1.0 and 1.5 to 3.0 mg kg respectively while Mn was evenly distributed in 3.0 to 6.0 mg kg range. In contrast, Fe distribution was scattered. A range of 0.45–1.23, 1.47–2.91, 2.86–11.13 and 4.9–15.2 mg kg Zn, Cu, Mn and Fe respectively across different mango sites were estimated. In the case of major nutrients (NPK), the frequency distribution of P and K indicated widely spread while N was confined to a smaller distribution range. Soil reaction (pH) was mostly found near neutral to slightly alkaline in nature. The ecological significance of this study indicated the need for proper nutrient management. Such information may be useful for conserving the mango based agroecology for future endeavor through the adoption of optimized micronutrient management technologies.","PeriodicalId":23334,"journal":{"name":"Tropical Plant Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86602115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
