Therefore, an experiment was conducted to analyze its level of desiccation and changes takes place during water loss. The results indicated that the reduction in seed moisture from 47.4 per cent leads to loss in viability. In which, the initial seed germination (100 %) declines slowly during desiccation and at the seed moisture content of 33.1 per cent it recorded 69 per cent germination at six days of exposure under ambient temperature (30±20C). Further moisture loss leads to drastic reduction in germination and hence, this could be the critical or lowest safe moisture content. In addition, the reduction in seedling vigour and enzymatic activity and increase in seed leachate were noticed during desiccation of the curry leaf seeds.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"15 1","pages":"38-41"},"PeriodicalIF":0.0,"publicationDate":"1970-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73248153","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}

Based on 11 morphological and quality characters namely, days to first flower, plant height (cm), number of primary branches, number of clusters per plant, number of pods per plant, pod length (cm), pod weight (g), number of seeds per pod, seed size (cm), 100 seed weight (g), yield per plant (g), these genotypes were grouped into 5 clusters showing fair degree of relationship between geographical distribution and genetic divergence. Cluster I, with 6 genotypes, was the largest cluster followed by cluster IV and V with 5 genotypes. The intra cluster distance was maximum (D=809.83) in cluster V. The maximum inter cluster distance (D2=2932.162) was recorded between cluster II and III. All cluster mean values are distributed in relatively distant clusters.
