The seeds were subjected to germination testing to identify the best seed source for raising Pinus gerardiana seedlings in the nursery. Significant differences were observed in germination percent, average seedling length and seedling vigour of seeds collected from different seed sources. The maximum germination of 83.00% was recorded in seeds collected from Jangi seed source followed by 74.00% germination in seeds collected from Purbani, 71.00% germination in seeds collected from Moorang in Kinnaur Forest Division whereas minimum germination of 36.00% germination was recorded in seeds collected from Luj in Pangi Forest Division. Similarly, maximum seedling length of 11.10 cm was recorded in seeds collected from Jangi followed by 10.50 cm in seeds collected from Purbani and 10.21 cm in seeds collected from Moorang in Kinnaur Forest Division whereas minimum seedling length of 7.70 cm was recorded from seeds collected from Luj in Pangi Forest Division. The maximum seedling vigour index of 921 was recorded in seeds collected from Jangi followed by seedling vigour index of 777 from Purbani and seedling vigour index of 724 from Moorang in a decreasing order whereas minimum seedling vigour index of 277 was recorded in seeds collected from Luj in Pangi Forest Division. It is recommended on the basis of present investigation that seeds of Pinus gerardiana should be collected from Jangi seed source in Kinnaur district for raising quality seedlings in the nursery.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"2 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132653376","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}

Asian (Malesian) flora through the adjacent mountain ranges of Myanmar. The area has very high rainfall and a great range of altitude (from c. 300 m to 4500 m). Despite increasing human pressure, the Park still contains large areas of species-rich, pristine tropical-type rain-forest and temperate forest, along with secondary forest. It is thus a notable haven for a very great diversity of pteridophytes (ferns and allies, including lycophytes), which form an obvious and often dominant part of the ground vegetation, with tree-ferns (Cyathea) above. However only the lower regions have been explored scientifically, up to c. 500 m altitude. A remarkable nine tenths of the altitude-range of the park remains entirely unexplored and its high-altitude Sino-Himalayan flora, still quite unknown, must be immensely rich, including the pteridophytes. A checklist of pteridophytes of the park is given here as known so far from all relevant herbarium-collections and from the authors’ own collections, altogether 184 taxa, though well over twice that number should be expected if a far-reaching scientific expedition could take place, which has not so far occurred.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114275674","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 drupes were subjected to the following natural and accelerated ageing treatments viz., control, accelerated ageing for 1 to 15 days at 40oC and 100% RH and naturally ageing (stored at ambient temperature) for 1 to 15 months. The accelerated and natural aged drupes were placed for germination in sand filled earthen pots and kept in sunlight. The experiment was conducted in a Completely Randomized Block Design with ten replications. Germination percentage, number of seedlings/100 drupes, time taken for initial emergence, root length, shoot length, dry matter production and vigour index were recorded 28 days after sowing. The result revealed that the teak drupes subjected to accelerated ageing for 12 days had higher germination (40.6 percent) against 8.2 percent in control and showed an increasing trend with increased period of accelerated ageing (though not very consistently) up to 12 days and thereafter germination was reduced. Whereas in natural ageing treatment, drupes aged 15 months recorded highest germination of 29.2 percent. In natural storage, months after months storage drupes germination was increased. From this study, it could be concluded that instead of storing the drupes over a period of time to natural release of dormancy, 12 days of accelerated ageing enhanced the germination and seedling vigour of teak drupes.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126220877","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}
