Distribution of essential oils in leaf tissue of an F2 population of Citrus
SummaryThe identification and distribution of 17 mono- and sesquiterpenes in an F2 population produced from selfing of an interspecific F1 hybrid is presented. A mode of inheritance for most of these components is attempted, percentages of leaf oil components and a correlation matrix are given.
Comparison of Leaf Components of Sweet Orange and Sour Orange (Citrus Sp.)
studies had shown that oxygenated compounds were important in food products. It seems that Citrus species had a profound influence on this factor. The goal of the present study was to investigate on flavor components of two Citrus species. In the early week of June 2012, about 500 g of leaves were collected from many parts of the same trees. Leaf components were extracted using water distillation method and then analyzed using GC and GC-MS. Data were analyzed using one-way analysis of variance and Duncan’s multiple range tests. The amount of oxygenated compounds ranged from 29.14% to 85.64%. Between two species examined, sour orange showed the highest content of oxygenated compounds. As a result of our study, can be concluded that the species used can influence the quantity of oxygenated compounds present in the oil
Investigations of the yield and quality of the oils from some hybrid and tetraploid mints*1
Hybrids produced by crossing Japanese mint with Mentba spicata, the common wild spearmint, gave good yields of oil per acre which was low in menthol content. Hybrids of Japanese mint with Mentba aqrratica produced oils high in menthol content but low in yield per acre. Both hybrids were more vigorous than the female parent, and one was resistant to mint rust. Two tetraploids of spearmint obtained colchicine treatment contained only traces of oil.
