Essential conditions should be performed, particularly in supporting plant growth, the safety factor for consumers and the use of amendments in improving the efficiency of phytoremediation. In general, it takes more than one type of the plant to be more effective in restoring a polluted environment. For this purpose, the selected plant species mus synergistically eliminate the types of pollutants present in the environmental media. Thus, the mixed plants process becomes very effective in removing many of the pollutants on site. In practice, mixed plants operations could be selected from one or a combination of simultaneous, sequential or alternating patterns, all of which must be adapted to polluted media conditions.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49524293","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}

In order to standardize the humid priming technique, okra seeds were subjected to humid priming for four different duration’s viz., 2, 4, 6 and 8 h, shade dried to original moisture content and subjected to evaluation of seed germination under shade net conditions in raised beds. The results revealed that 4 h of humid priming was statistically significant to the rest of the durations, with respect seed germination and seedling growth. With respect to anatomical potential, the radicle length (3.39mm), cotyledon length (6.69mm) and cotyledon width (6.30mm), recorded by humid priming (4 h) was 62.2 %, 6.4 % and 2.6 % higher than control seeds. The second experiment conducted to compare the efficacy of hydro priming, spin priming, polymer coating and combination of humid priming + seed coating. The study revealed that seeds subjected to combination of humid priming (4 h) + seed coating (3g kg-1) recorded highest physiological potential in terms of germination percentage (87 %), seedling length (20.2 cm), dry matter production (421.3 mg), vigour index (1765), root volume (3.5 cm3) and root sheath (2.560 g) while the control recorded only 70 %, 15.1 cm, 328.7 mg, 1055, 2.0 cm3 and 1.532 g, respectively.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42179004","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}
