کچھ یادیں کچھ باتیں
یہ اُن دنوں کی بات ہے جب میں رسمی تعلیم کے ایک مرحلے کی تکمیل کے بعد عملی زندگی میں قدم رکھنے کی جستجو میں تھا کہ میری ملاقات ایک ایسے شخص سے ہوئی جس نے زندگی میں درپیش مسائل سے نبردآزما ہونے میں بہت مدد کی اوراب بھی تادمِ تحریر اِن کے علمی و ادبی فیض سے استفادہ جاری ہے۔
جون ۱۹۹۲ئ کی بات ہے کہ خالد بھٹی (مرحوم) نے اپنے حاوی کالج میں طلباء کی خوشنویسی کی تربیت کے لیے بطور خوش نویس معلم مجھے خدمات سر انجام دینے کے لیے آمادہ کیا اور اسی سلسلہ میں ایک اشتہار ’’حاوی کالج کی فخریہ پیشکش‘‘ تدریس ِ خطاطی کی باقاعدہ کلاس کی کتابت کے لیے خالد بھٹی کے ہمراہ اِن کی رہائش گاہ پر حاضر ہوا تو دیکھا کہ ایک تیس بتیس سالہ خوش شکل، خوش رنگ ، خوش لباس ، دبلا پتلا ، باریش شخص سامان کتابت کے ساتھ اپنی مسندِ خاص پر برا جمان ہے اور جلد ہی یہ احساس بھی ہوا کہ وہ خوش اخلاق اور مہمان نواز بھی ہے۔ ازاں بعد ملاقاتوں کا سلسلہ جاری رہا۔ رب کریم کی مجھ پر کرم نوازی ہوئی کہ مارچ ۱۹۹۳ئ میں میں اُن کارفیق کا ر بن گیا اور ہم گورنمنٹ مڈل سکول نمبر ۲ میں اکٹھے رہے ۔ اُن سے رفاقت کا سلسلہ جیسے طول پکڑ تاگیا۔ اُن کی شخصیت کے ہر پہلو سے مجھے آشنائی ہوتی گئی ۔
۱۹۶۲ئ میں عارف والا کے مضافاتی شہر چک نمبر ۳۷/ ای۔بی میں جنم لینے والا محمد اکرم جس نے ابتدائی تعلیم اپنے والدِ محترم سے حاصل کی اور محض چھ سال کی عمر میں والد کا سایہ سر سے اُٹھ گیا ۔ پھر یتیمی کی ستم ظریفی اور غریب الوطنی کی پُرخار راہوں سے گزرتے ہوئے میٹرک کا...
E come across unpleasant news regarding people from different walks of lives. Teachers Judges, Doctors, Police Officers and so on are allegedly reported for committing malpractices and corruption. This is not the problem in our country. It is a worldwide problem. It is evident that the education which is given is not upto the mark. Though Civic education or value education is being given across the country but it has not been proven that much effective which can make character and personality of an individual strong engouh to stops a person from committing the mentioned wrongs. On the other hand Islamic perspective of Civic education is more comprehensive and covers different angles and aspects of human personality and life. Islam aims to make an individual internally disciplined in the manner where he/ she does not do right things and acts just because he/she is under the eye of Camera but he/she does the right act because he/ she is supposed to do so.
In the present study, a series of experiments were conducted in the Botanic Gardens of the Department of Botany, University of Agriculture, Faisalabad to test the relative effectivness of the three osmolytes in alleviating the adverse effects of drought stress on maize plants. The osmolytes were applied through different modes at different growth stages of maize plants under non-stress or water stress conditions. In the first experiment, varying levels (0, 30 and 60 mM) of each of the osmolytes were applied as foliar spray and presowing treatment of seeds of two cultivars (Agaiti-2002 and EV-1098). The plants raised from the treated seeds were grown in plastic pots filled with sandy loam soil under greenhouse conditions. After two weeks of the imposition of water stress, different levels (0, 30, and 60 mM) of each of the osmolytes were exogenously applied as a foliar spray to maize plants at the seedling, vegetative or both seedling and vegetative stages when grown under non-stress or water stress conditions (60% field capacity). Tween-20 (0.1%) was used as a surfactant for foliar spray. It was found that 30 mM of GB, or proline or trehalose was the most effective in promoting seedling growth under water stress conditions. However, GB and proline were more effective than trehalose in ameliorating the adverse effects of water stress on growth of both maize cultivars. It was found that effective concentration of exogenously applied osmolytes through seed soaking or through foliar application is 30 mM. During the 2 nd experiment the effective concentrations of these osmolytes (GB, proline and trehalose) as estimated from the 1 st experiment were applied as pre-sowing seed treatment and as foliar spray at different growth stages (seedling, vegetative and seedling+vegetative) as in the 1 st experiment to observe their effects in inducing drought tolerance maize plants in relation to various physiological and biochemical attributes. Exogenous application of osmolytes as presowing seed treatment or as foliar spray at different growth stages increased the photosynthetic rate of the plants of both cultivars that was associated with stomatal as well as non-stomatal factors. Plant water status as reflected by leaf water potential and leaf relative water content (RWC) was improved by the exogenously applied organic solutes and it was associated with leaf osmotic potential, endogenous GB and proline, which suggests the role of these osmolytes in osmotic adjustment. Exogenous application of these osmolytes increased the accumulation of nutrients particularly K, and shoot nutrient use efficiency in maize plants under water stress conditions. Exogenous application of compatible solutes enhanced the antioxidant capacity of drought stressed maize plants by increasing the activities of antioxidant enzymes (SOD, POD and CAT) and non-enzymatic compounds (phenolics, tocopherols and ascorbic acid) which is evident from the reduced MDA contents determined in the present study. Exogenously applied different osmolytes enhanced the seed and seed oil quality of both maize cultivars. Seed sugar, seed oil, seed protein, seed macro- and micronutriets increased due to exogenous application of these osmolytes. Moreover, improved seed oil quality was associated with enhanced oil unsaturation in terms of increased in oleic and linoleic acid contents as well as the oil lipophilic antioxidants (tocopherols, phenolics, flavonoids) which in-turn enhanced the oil antioxidant activity. Overall, exogenously applied different compatible solutes as a seed treatment or foliar application improved growth and yield of maize pants. Osmolyte-induced enhancement in growth and yield under water stress conditions was associated with increase in net CO 2 assimilation rate, plant water status, antioxidant capacity and nutrient accumulation, particularly of K. However, further studies are required to explicitly elucidate the mechanism of organic osmolytes influx through epidermis and target enzymes or metabolites to induce stress tolerance in plants. Moreover, further studies are important to work out cost-benefit ratios of the use of different organic osmolytes used in this study. This information will be undoubtedly beneficial for stakeholders, particularly the farmers.
