الرّسم العثماني وأثره على المعاني القرآنية

The Holy Qur’an is miraculous in its words, methods, organization, statements, drawings and writing, as cited and agreed by all researchers, we aim through this research to: define the Ottoman drawing in Arabic language, terminologically, demonstrating its benefits, the rule of commitment to it, weighing between sayings, demonstrating its six rules, explaining and discussing the differences between the Quranic words drawings and mentioning several examples. The most important results of this research are: 1- The opinion which comforts one's self is the commitment to Ottoman drawing, and not to be written by modern spelling methods. 2- The Ottoman drawing has multiple benefits and advantages, which are not available in any other, so that it attracts commitment and reservation. 3- It has a very significant concurrence between the drawing and the meaning of the words and verses of Quran. 4- The Qura’nic word drawing strengthens the meaning and gives the full dimensions; achieving the honesty of Allah's saying: "and whose words can be truer than those of Allah?". 5- The letters' contiguity of Quranic word, knowing its characteristics embodies the meaning with the best picture. 6- The miracle of Ottoman drawing is a modern issue that Abdalaziz Ad-Dabbagh calls the most famous and the oldest one who declared this.        The most important recommendations made in this article are: 1- Conducting more researches about the benefits of Ottoman drawing, where it still needs more studies to be conducted, and more thoughts and meditations. 2- The spread of Ottoman drawing commitment culture between Quran teachers and students. 3- Obligating all Quranic associations that adopts Quran writing to write in Ottoman drawing, and prevent any other forms of writing. 4- Obligating all students and researchers to depend on Ottoman drawing through their studies and researches; which establishes a promotion to spread its culture. 5- Guiding the researchers for more studies on this topic, throughout a focused studies and clear scientific plans.

Evaluation of Synthetc Derived Wheat Lines for Heat Stress Using Physiological and Agronomic Traits

Wheat production is decreasing continuously due to heat stress in the developing countries especially Pakistan. Every 1 ?C rise in temperature is resulting in 10% reduction in the yield of wheat worldwide. Therefore in order to overcome shortage of food in the near future better analysis of the wheat crops as well as improved research mechanisms are needed to enhance heat resistance in the existing wheat varieties. Present study was conducted to assess heat tolerance variation among thirty synthetic-derived wheat lines in order to identify new sources of diversity that could accelerate the development of improved wheat genotypes better suited to meet the challenges posed by changing climate in Pakistan. Plants were grown in plastic pots and heat stress was applied after post anthesis stage to determine the effect of heat stress on various morphological, agronomic and physiological traits. Heat stress significantly affected leaf area (LA), plant height (PH), number of fertile tillers (FT), Spike length (SL), Spikelet/spike (Sp/S), No. of seeds/Spike (NOS/S), 1000 seed weight (TSW), chlorophyll a and bcontent of leaves, membrane stability index (MSI) and also affected levels of proline. Statistical analysis of all the traits showed significant reduction in the particular trait as compared to their control data sets. Higher percentage reduction under heat stress reduced yields in (SDL1, 31.00), (SDL6, 32.00), (SDL29, 30.00) while minimum reduction under heat stress and maximum yield was observed for (SDL4, 45.00), (SDL5, 48), (SDL9, 44), (SDL12, 45.00), (SDL15, 49.00), (SDL19, 51.00), (SDL22, 45.00), (SDL23, 45.00) and (SDL27, 46.00) respectively. Reduction in physiological traits was recorded as 24.46% reduction in chlorophyll a (Chl-a), 28.19% chlorophyll b (Chl-b), 29.17% proline (Pro) content of leaf, 16.36% membrane stability index (MSI). In the same way in morphological trait a relative decrease in plant height (PH) 12%, days to physiological maturity (DM) 7.59%, fertile tillers (F/T) 21.43%, leaf area (LA) 25.58%, , spike length (SL) 25%, number of seeds per spike (NOS/S) 15.38%,and 1000 seed weight (TSW) 19.23%was observed. As a result it was observed that relative decrease in the yield contents in (SDL4), (SDL5), (SDL9), (SDL12), (SDL15), (SDL19), (SDL22), (SDL23) and (SDL27) was lesser as compared to all other genotypes so they can be considered as heat tolerant genotypes with potential to enrich genetic background of local wheat cultivars and can be used in breeding programs for the improvement of wheat production and can overcome food shortage in future.
