متن کاملChemical Composition of Seed and Seed Oil from Iranian Commercial Date Cultivars
In the present study, the seeds of two date palm (phoenix dactylifera L.) cultivars, Mazafati and Kalutah, were analyzed for their physical properties and chemical composition. Studies were also conducted on properties of oil extracted from the seeds and its fatty acid composition. The seeds constituted about 6-10% of the fruit weight.

A limiting factor for prodution of turf grasses in temperate regions is their low level of cold tolerance. In order to elucidate the cold tolerance, physiological and biochemical responses of two turf species, this study was conducted at a controlled environment greenhouse of Faculty of Agriculture in Shiraz University, Shiraz, Iran by a factorial experiment in completely randomized design with...
متن کاملCROSS INOCULATION OF TWO TALL FESCUE GENOTYPES WITH NEOTYPHODIUM ENDOPHYTIC FUNGI AND ITS DETECTION USING AFLP MARKER
Mutual relationship between pasture grasses and Neotyphodium fungal endophytes is of great importance in grass improvement. Two endophyte containing tall fescue genotypes (75 and 83) and their endophyte free ramets were used in this study. Endophytes were isolated from tall fescue genotypes 75 and 83 and used in three methods of inoculation including Latch and Christensen approach, insertion of...
