Molecular systematic and productivity evaluation of some ecotypes of Mentha longfolia under different ecological conditions
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 9
Abstract
This work was carried out during the two successive seasons of 2015/2016 and 2016/2017 to assess the molecular systematic and genetic relationship between two Mentha longfolia ecotypes, which collected from South Sinai (St. Catharine) and Siwa Oasis in Egypt through ISSR molecular markers, Then evaluating the productivity of them under different ecological conditions. The experiment was conducted at two different locations in newly reclaimed lands as follows: Baloza (North Sinai Governorate) and Siwa Oasis (Matrouh Governorate). The results of molecular markers showed high similarity values between the studied ecotypes were 92%. ISSR analysis confirmed that the Mentha longfolia from Catharine and the Mentha longfolia from Siwa Oasis are genetically similar and have the same species. On the other hand, the results of productivity experiment indicated that all parameters under the study i.e. fresh and dry weight of herb/plant or feddan, essential oil percentage, essential oil yield /plant or feddan and essential oil constituents were varied according to location and ecotype. The best location for cultivation of these ecotypes was at Baloza location and the best productivity was for Siwa ecotype which recorded the highest quantity parameters in this respect. Also, GC-Ms analysis of volatile oil indicated that the major compounds in Siwa ecotype oil were 1,8 Cineole, 1-Menthone and Pulegone. While, Piperitone oxide, Piperitone, Piperitenone and 1,8 Cineole were major compounds in Catharine M. longfolia ecotype oil.
