Crop Water Stress

A study was conducted to determinethe feasibility of using crop water stress index (CWSI) to schedule irrigation of eight species of freeway landscape plants, Acacia redolens B.R. Maslin, Acacia salicina Lindl., Caesalpinia pulcherrima Sw., Cassia nemophila A. Cunn. ex Vogel, Cercidium floridum Benth., Eucalyptus microtheca F.J. Muell., Nerium oleander L., and Prosopis chilensis Mol. Nerium oleander and C. pulcherrima were suited to the use of the CWSI, tolerated repeated exposures to CWSI values of 0.6, and remained aesthetically acceptable. Irrigation of N. oleander via the CWSI resulted in a 19% reduction in water use, compared to the conventional method. CWSI data of other species were too variable, and, thus, irrigation could not be scheduled by CWSI values. Variability was attributed, in part, to lack of a dense canopy, which is necessary to fill the view of the infrared thermometer.

Provenance trials of Eucalyptus microtheca F. Muell. were established in the central Coastal Plain and the northern Negev in 1983, using the seed of 303 trees from 73 provenances in Australia bulked into 21 provenance groups by the CSIRO Division of Forest Research. Survival, height, and diameter development of E. microtheca in the central Coastal Plain were lower than those of Eucalyptus camaldulensis Dehn. In the northern Negev, several progenies of E. microtheca had better growth and survival rates than E. camaldulensis. Variations within provenance groups in growth and survival were very large. Relations between the measured traits and variables describing the seed source of E. microtheca indicate the existence of latitudinal and longitudinal clines. Provenance groups most suitable for use in the northern Negev are Springsure, Qld. (No.14), Rockhampton, Qld. (No. 15), and Walgett, N.S.W. (No. 20).

This study aims at investigating the chemical composition, antimicrobial and antioxidant activity of some extracted essential and fixed oils from leaves of Eucalyptus microtheca plant grown in Iraq. Analysis of the isolated oils has been achieved by gas chromatography coupled with mass spectrometry gas chromatography–mass spectrometry (GC-MS) Technology. The study reveals existence of sixteen compounds. Camphene (20.60%), 4-carene (18.53%), 1,8-cineole (11.96%), terpin-4-ol (8.70%) and p-cymene (8.39%) were the highest components in these essential oils. While nine compounds were obtained as fixed oils, pentadecanoic acid (36.47%) and cis-vaccenic acid (30.31%) were the major components. The antimicrobial activity of the leaves extracts was evaluated against six different gram-positive and Gram-negative bacteria using disk diffusion method and exhibited good inhibition activity. Moreover, antioxidant assay (free radical scavenging activity) demonstrated good activity for the extracted oils. The results show that the aerial parts (leaves) of the Iraqi E. microtheca plant possess antibacterial and antioxidant properties and may suggest it as a good candidate to use for medicinal purposes.

Eighty five samples were taken from patients suffering from pneumonia. Seventy-eight isolates were diagnosed as following: Staphylococcus aureus (23), klebsiella pneumoniae (29), Streptococcus pneumoniae (15), Serratia sp. (4), Haemophilus influenzae (4) and Pseudomonas aeruginosa (3). The clinical isolates were tested for antibiotics sensitivity. They appeared highly resistance to penicillin G and Ampicillin at percentage 89.7 and 84.6% respectly while the results showed highly sensitivity to streptomycin at percentege of (12.8%). To study the antibacterial activity of Alium sativum, Eucalyptus microtheca leaves and Cydonia oblonga seeds extracts, five multi resistant strains were used by using agar well diffusion and disk methods at concentrations of (24, 12, 6, 3)%. The agar well diffusion was prefered for both of Alium sativum and Eucalyptus microthesca extracts while both methods were prefered for Cydonia oblonga extract by measuring inhibition zones .The results showed antibacterial activity of Alium sativum on S.aureus and S. pneumoniae at concentration 3-24 % and for klebsiella pneumoniae at concentration of 6-24%While it was 12-24%for Serratia sp. and Pseudomonas aeruginosa. Eucalyptus microtheca extracts showed antibacterial at concentration of 24-3%for S.aureus, S. pneumoniae and Ps. aeruginosa. While K. pneumoniae and Serratia sp sensitive at concartatins of 24%. The ethanol and oil extracts of Cydonia oblonga seeds had anti bacterial activity at all concentrations for all strains except Serratia sp. showed sensitivity at concentrations of 24-6%for both extracts.
