Recent research revealed the seed borne nature of Xanthomonas cucurbitae . In this study, seeds wrapped in muslin cloth were dipped in various treatments involving hot water and chemicals. Hot water treatment of seeds at 55&deg;C for both pumpkin and bottle gourd isolates resulted in minimum (28.73 and 23.33%, respectively) seedling infection. In vitro evaluation of fungicides and antibiotic (streptocycline) by using paper disc method revealed that Bordeaux mixture and copper oxychloride to be most effective against pumpkin and bottle gourd, respectively. Under chemical seed dip treatments, the minimum number of infected seedlings were recorded with streptocycline (37.64%) and copper oxychloride (40.80%) for pumpkin and bottlegourd, respectively. For both the isolates, maximum seed germination was recorded in seeds treated for 720 minutes (98.20 and 98.60%, respectively). A combination of streptocycline and copper oxychloride as seed treatment for three hours gave best results for both the isolates (16.33% and 15.67%, respectively). Under pot house conditions, combining streptocycline (100 ppm) and copper oxychloride (3000 ppm) as a seed dip treatment for three hours was found to be the most effective. The recorded minimum disease severity was 18.00 and 22.00%, respectively.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135103501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article will describe the seed ageing / repair hypothesis which has formed the basis of new vigour tests, how the hypothesis can explain differences in vigour and its use in vigour tests. The development and modification of ISTA validated vigour tests, and the extensive research that has examined the application of these tests to other species are described. Other approaches to vigour testing, based on seed response to stress, respiratory indices of vigour and the cell cycle are described and evaluated. The current and potential use of advanced technologies, such as image analysis, in vigour testing, and molecular research based on proteome analysis and DNA repair in Arabidopsis thaliana are described. The radicle emergence test, possibly using image analysis, is highlighted as having great potential for future application to a wide range of species. New approaches to vigour testing may be based on new technologies and molecular markers, but the need for rigorous evaluation of these approaches using commercial seed lots of crop species is emphasised.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"45 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67091053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is highly variable and is an important part of the adaptation of many species to their habitat. Often, two questions are asked about seeds that failed to germinate in a germination test: (1) are they non-viable or dormant, and (2) if dormant do they have PD and how is it broken? We provide an overview on how to approach studies of species with PD for which few or no data are available. Information about habitat environmental conditions during the seed stage can be used to formulate hypotheses on dormancy-breaking and germination requirements. These hypotheses can be tested by a move-along experiment. There are three levels of PD, and they are distinguished by the conditions required to break PD and promote germination. Seeds with non-deep PD (the most common level of PD) require different conditions for dormancy-break and germination, i.e. a change in the season, while those with intermediate and deep PD germinate at the dormancy-breaking conditions, e.g. during a long period of cold stratification. Knowing how to break PD enhances testing for seed viability and helps ensure high germination percentages of viable seeds.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67091505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
