  The objective of the present study was to examine the relationship between various seed quality tests and field emergence of the new and old wheat cultivars. Laboratory and field tests were conducted during 2003 and 2004 in NWFP Agricultural University Peshawar, Pakistan, to investigate the suitability of various Laboratory vigor tests, to rank quality of commercial seed lots and to predict seedling Field Emergence (FE) of thirty-two samples of four wheat varieties. Seeds of four wheat cultivars Takbeer 2000, Haider 2000, Bakhtawar-92 and Fakhri Sarhad were produced in eight different location of NWFP-Pakistan during 2003 and 2004. Mature seeds were harvested, threshed and cleaned before determining standard germination and other vigor tests. Results showed that among all tests, Germination Index (GI), Accelerated Aging (AA) and Electrical Conductivity (EC) provided the best estimate of seed vigor for the four wheat cultivars, both for ranking seed lots quality and predicting field emergence. The GI, AA and EC tests better indicated seed lot quality and predicted FE than SG of the four cultivars over the 2 years followed by Radical Length (RL). The Electrical Conductivity (EC) result was not only poorly related to FE, but also poorly related to the Standard Germination (SG) of a wide range of seed lots of the four varieties that varied in viability. Initial count of Standard Germination (SGi) generally performed more poorly than the other vigor tests. From this study and previous work on wheat crop, we conclude that GI, AA and EC test for wheat crop have the potential to be developed as improved vigor tests for ranking seed lot quality and predicting seeding performance under temperate regions of the world.

  Background and Objective: Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Streptococcus Pneumoniae causing pneumonia in India, Pakistan, Bangladesh and Afghanistan in children under 5 years of age and older adults. Therefore; the present research was design to study the different microbiological aspects of Streptococcus pneumoniae. Materials and Methods: A total of 480 sputum samples were collected from pneumonia patient at different government hospitals of Quetta. The detail of patient’s gender, age, economical status and educational status were taken on performa. Sputum samples were inoculated into selective strep agar Streptococcus pneumonia colonies were observed on plates and confirmed through different biochemical tests and PCR. Results: Total 480 samples were collected in which 36.6% were Streptococcus pneumoniae positive and 63.3% were negative. The sex wise ratio showed that female (24.10%) were more affected with pneumoniae as compare to male (12.50%). The pneumonia infection age wise distribution was 9% in 1-10 years old patients, 16% in 10-20 years old patients and 11% in 20-30 years old patients. The status wise distribution of pneumonia infection showed that lower class (16%) was more affected as compare to middle class and higher class of Quetta. The percentage of pneumonia infection in hazara race was 14%, in Pathan 8.30%, in Punjabi 7.60% and in Baloch 6.60%. It was seen that illiterate patients were more affected with pneumonia infection (28.3%) than literate (8.3%). The Streptococcus pneumoniae was confirmed through gram staining, different biochemical tests, different sugar fermentation tests and PCR. Whereas confirmed by PCR showed clear band of 329 kb of ply gene. Conclusion: It was concluded that the rate of pneumonia infection was high in female and lower class was more affected with pneumonia.
