Drought-induced loss in crop yield probably exceeds losses from all other causes, since both the severity and duration of the stress are critical. Drought affect is noticeable at all level of organization from cellular to whole plant level. Manifestation of combination of morpho-physiological changes decides the ability of plant to overcome limited water supply and sustain its growth. Plant drought tolerance does not remain same at all stages of wheat development due to the variable responses. Therefore, it is important to develop relationship between drought and yield traits at different stages of wheat development. Drought at booting or flowering stage of wheat development shows strong relationship with grain yield. While seedling growth shows higher correlation with drought tolerance in wheat under drought field condition. Relative yield for comparison of different genotypes made good indicator of tolerance potential.</p> 2018-11-10T00:00:00+00:00 ##submission.copyrightStatement## http://journals.psmpublishers.org/index.php/ijnas/article/view/238 Incidence of Hypertension among Various Age Groups in Narowal, Pakistan 2018-11-10T07:51:10+00:00 Muhammad Naeem Iqbal driqbalnaeem@hotmail.com Asfa Ashraf sundausnaeem@yahoo.com Iqra Iqbal driqbalnaeem@yahoo.com Azara Iqbal admin@psmpublishers.org Saman Alam samanalam220@gmail.com Fakhar-un-Nisa Yunus fakhar_yunus@yahoo.com <p>The data about the prevalence of hypertension of approximately one hundred patients was collected by interviewing them in Narowal, Pakistan. The data had been analyzed to determine the relative occurrence and incidence of hypertension by different age groups. The analysis showed the prevalence of hypertension was more in females (64%, n=64/100) as compared to males (34%, n=34/100). Hypertension was more prevalent in age group 38-47 years (32%) and less prevalent in age group 68-77 years (6%). In our sample population the prevalence of hypertension by age group 18-27 years was 13%, age group 28-37 years was 16%, age group 38-47 years was 32%, age group 48-57 years was 18%, age group 58-67 years was 15% and by age group 68-77 years was 6%. Known as “the silent killer”, the disease may prevail without symptoms for prolonged periods so there is requirement of investigations to know the exact rate and risk factor of this overwhelming disease.</p> 2018-11-10T07:50:29+00:00 ##submission.copyrightStatement##
