Chemical and wood anatomical properties of tumorous wood in a Turkish white oak (Quercus robur subsp robur)
Chemical and anatomical properties of tumorous and normal wood of
Quercus robur L. subsp. robur were compared. Tumorous growth appeared as
a result of topping stress. Orientation of cells was severely disrupted
in the affected wood. In cross section, aspects of cells changed
abruptly from transverse to longitudinal, and in tangential section all
wood elements appeared to turn around each other like a fingerprint.
Vessel elements and fibres of affected wood were shorter than those of
healthy wood. The vessels of affected wood were smaller in diameter
especially in the earlywood. On the other hand, multiseriate ray height
was shorter than that of normal wood. In addition, perforated ray cells
occurred. The ray and axial parenchyma cells of tumorous wood contained
dark coloured phenolic compounds. Normal wood had calcium oxalate
crystals, while tumorous wood did not. Chemical analyses showed that
hemicellulose content and solubility rates in 1\% NaOH, cold water, hot
water, and alcohol-benzene were higher than those of normal wood.
Cellulose and ash contents of tumorous wood were slightly lower than in
normal wood. In addition, air-dry specific gravity of tumorous wood was
higher than that of normal wood

FATTY ACID, MINERAL AND PROXIMATE COMPOSITIONS OF VARIOUS GENOTYPES AND COMMERCIAL CULTIVARS OF SWEET ALMOND FROM THE SAME ECOLOGICAL CONDITIONS
WOS: 000435780500060This study was carried out on the fatty acid, mineral and proximate compositions of ten sweet almond genotypes and two commercial varieties named as Ferragnes and Ferraduel grown in the same ecological conditions known as the Firat riverside region during two consecutive years. In this context, the crude oil (Co), crude protein (Cp), total sugar (Ts), total ash (Ta) and moisture (Mo) contents from the almond genotypes and cultivars ranged from 48.69 to 55.8%, 20.41 to 25.82%, 2.92 to 5.27%, 3.29 to 4.66% and 2.52 to 3.75%, respectively. The genotypes and cultivars showed a varied mineral content as well. Potassium (K) was the main mineral in all genotypes and cultivars, ranging from 679.53 to 986.63 mg100 g(-1) ; phosphorus (P) was the second most abundant mineral, ranging from 584.57 to 697.31 mg100 g(-1) ; followed by magnesium (Mg) and calcium (Ca), ranging from 325.27 to 381.93 mg100 g(-1) , 250.15 to 332.19 mg100 g(-1) , respectively. Of the identified fatty acids, oleic acid (Oa) (69.76-72.02%) was the predominant fatty acid, followed by linoleic acid (La) (18.82-21.62%), palmitic acid (Pa) (5.627.76%), and stearic acid (Sa) (1.20-1.69%). Other fatty acids were present at trace amounts. The unsaturated (Ufa)/saturated fatty acid (Sfa) ratios ranged from 9.29 to 12.12. From the results of the present study, we can conclude that the kernels of almond genotypes and cultivars are being potential sources of valuable oil which might be used for edible and other industrial purposes
