معزز اسا تذہ کرام اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پر اظہار خیال کرنا ہے وہ ہے:’’ماں کی شان ‘‘
صدرِ ذی وقار!
ماں کا نام جب زبان پر آتا ہے تو جسم کالواں لواں سراپا ادب واحترام بن جاتا ہے۔ دل میں ماں کی محبت کی شمع روشن ہو جاتی ہے، تمام بدن عجز وانکساری کے جذبات سے معمور ہو جاتا ہے، روح انسانی طراوت اور تازگی محسوس کرتی ہے اور زندگی کی گاڑی شاہرا ہ حسن و جمال پر رواں دواں ہو جاتی ہے۔
صدرِ محترم!
ماں کیا ہے، ماں ایک گلشنِ حیات کا تر و تازہ گل سر سبز ہے جس پرکبھی پژمردگی نہیں چھاتی ، ماں ایک ایسا بار آور شجر سایہ دار ہے جو کبھی خزاں آشنا نہیں ہوتا، ماں ایک ایسی شمع مستنیر ہے جس کا روح پروانوں کی طرح طواف تو کرتی ہے لیکن جل کر راکھ نہیں ہوتی۔
محترم صدر!
ماں ایک صنف نازک ہے، جو ایک وقت میں اپنے باپ کی گود میں ہوتی ہے، جس پر ایک وقت ایسا بھی آتا ہے کہ بھائی اس کے سر پر دستِ شفقت رکھتا ہے، زندگی کے حسین وجمیل لمحات وہ بیوی بن کر بھی گزارتی ہے۔ لیکن وہ ساعتیں جو اسے مناصب ِرفیعہ پرمتمکن کرنے کا باعث بنتی ہیں وہ صرف اسے ماں بن کر ہی حاصل ہوتی ہیں۔
معزز سامعین!
قرآن و حدیث عظمت ِماں کے شاہد ہیں ، تمام رشتے مقدس ہوتے ہیں۔ والد کا رشتہ عظیم ہوتا ہے، یہ گھر کا سربراہ ہوتا ہے، سارے گھر کی ذمہ داری اس پر ہوتی ہے، بچوں کی تربیت کا مرحلہ ہو، خاندانی امور اپنانے کی بات ہو، باہمی لین دین ہو، عزیز و...
The purpose of this study is to find out the significant effect of self-concept on learning motivation of VII grade students in SMP Negeri 4 Palu on Islamic Religious Education subjects, (2) knowing the effect of learning discipline on learning motivation of VII grade students at SMP Negeri 4 Palu in the eyes of Islamic Religious Education subjects and (3) determine the effect of self-concept and learning discipline on learning motivation of grade VII students in SMP Negeri 4 Palu on Islamic Religious Education subjects. This study uses a quantitative approach. The population in this study were 220 class VII students of SMP Negeri 4 Palu. The sample was determined using proportional random sampling technique using a formula developed by Isaac and Michael, so that a sample of 135 students was obtained. Primary data were obtained using a questionnaire. Data analysis techniques include descriptive analysis, and regression tests using simple regression and multiple regression. The results showed that (1) There was a significant influence between self-concept on learning motivation of VII grade students in SMP Negeri 4 Palu on Islamic Religious Education subjects, with a significance level of 5%, the magnitude of the effect of self-concept variables on students' learning motivation was 0, 615 means having a high influence (2) There is a significant influence between learning discipline on learning motivation of VII grade students in SMP Negeri 4 Palu on Islamic Religious Education subjects, with a significance level of 5%, the magnitude of the effect of the discipline of learning variables on motivation student learning is 0, 565, (3) There is a significant influence between self-concept and learning discipline on learning motivation of grade VII students in SMP Negeri 4 Palu on Islamic Religious Education subjects, with a significance level of 5%, the high influence of concept variables self and discipline of learning towards learning motivation of VII grade students of SMP Nege ri 4 Palu in Islamic Religious Education subjects is 0, 615. The contribution of self-concept variables and learning discipline to learning motivation variables is R2 x 100% or 0, 6152 x 100% = 37.9%, the remaining 62.1% is determined by other variables outside of this study include the level of interest, talent, attention, parenting parents and others.
Potato is a prime crop in ensuring food security locally as well as globally in the face of changing world demographic scenario as it provides more energy per unit of land and time (216 MJ/ha/day) than any other main staple food crop. However, potato crop is not as productive in subtropical areas as it is in temperate climate. This is attributed to abiotic (e.g. salinity) stress factors which are further aggravating by urbanization, industrialization, climate change and use of underground saline water for potato production due to shortage of freshwater in most of arid and semi-arid regions of the globe. Therefore, a pot culture study, comprised of four experiments was conducted to investigate the role of SA on morpho-physiological, bio-chemical, enzymatic and ionic attributes that can be used for characterization of salinity tolerance in potato cultivars. Tubers were planted in plastic pots, using fine sand as growth medium and half strength Hoagland solution was applied to plants as nutrient medium. In first experiment, screening of 13 different potato cultivars for salinity tolerance was carried out on the basis of morphological and ionic attributes against six salt (NaCl) stress concentrations (0, 2.5, 5.0, 7.5, 10 and 12.5 dS m-1). Cultivars were categorized into tolerant and sensitive ones on the basis of their performance in 1st experiment. One most tolerant (N-Y LARA) and one most sensitive (720-110 NARC) cultivar were selected for further study. Moreover, in 2nd experiment, effect of different salt (NaCl ) stress levels (0, 2.5, 5.0, 7.5, 10 and 12.5 dS m-1) was investigated on physiological, biochemical, enzymatic and ionic attributes of salt sensitive and salt tolerant potato cultivars (screened out in first experiment). Furthermore, an optimization experiment (3rd) was carried out to identify the best salicylic acid (SA) concentration among various SA levels (0.0, 0.25, 0.5, 0.75, 1.0 and 1.25 mM) by foliar spray under saline (5 dS m-1) environment to test salt tolerance potential of sensitive and tolerant potato cultivars (identified in first study). Additionally, salt tolerance potential of tolerant and sensitive potato cultivars was evaluated under saline (5 dS m-1) and non-saline environment without and with foliar spray of optimized concentration of SA (0.5 mM) vis-à-vis various physiological, biochemical, ionic and antioxidant attributes. Results of 1st and 2nd experiments depicted that salt stress significantly reduced shoot length (SL), root length (RL), shoot fresh weight (SFW), root fresh weight (RFW), shoot dry weight (SDW) and root dry weight (RDW), potassium contents (K+), photosynthetic activity (Pn), transpiration rate (E), water use efficiency (WUE), stomatal conductance of CO2 (gs), substomatal CO2 (Ci), water potential xiv (Ψw), osmotic potential (Ψπ), turgor potential (Ψp), total chlorophyll contents (Chl.), and total soluble protein content’s attributes. However, mean emergence time (MET), sodium contents (Na+), Na+: K+, melondialdehyde contents (MDA), proline contents, total phenolic contents, superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activities increased with increase in salt stress severity against six salt stress levels. From 3rd experiment, 0.5 mM salicylic acid (SA) concentration proved to be the best for inducing salt tolerance in both the potato cultivars. Furthermore, findings of 4th experiment clearly indicated that SA (0.5 mM) significantly enhanced salt tolerance potential of both the potato cultivars by alleviating drastic effects of salt stress on ionic, water relations, physiological, biochemical and enzymatic attributes as mentioned in 2nd experiment. Overall, it can be extracted that salt stress is injurious for potato growth and productivity and exogenous application of SA (0.5 mM) proved effective for enhancing salt tolerance potential of potato. However, SA effect was more pronounced on N-Y LARA than 720-110 NARC reflecting that former one was tolerant to salt stress while the latter one was susceptible. Besides, one can establish that Ψp, LRWC, Pn, E, WUE, gs and protein might directly be linked with growth and tuber yield attributes as they are negatively affected by salt stress in the same way as salt stress affected growth attributes in experiment one (Table-4.1.19) and tuber’s yield in experiment four (Table-4.4.1), respectively. In view of salt resistance potential of N-Y LARA and efficacy of low concentration of SA (0.5 mM) to further mitigate salt stress effect, cultivation of N-Y LARA along-with foliar application of SA (0.5 mM) may be recommended in saline soil.
