So, two trails were conducted at El-Hajarsh Village, Center of Kafr Saqr, Sharkia Governorate, Egypt, in 2013 and 2014 growing seasons to determine the effect of application methods and treating with various growth promoter substances and their interaction on productivity of maize hybrid single cross 10 (SC 10). A strip-plot design with four replications was used. Three application methods i.e. soaking, foliar application and soaking + foliar application were organized in the vertical plots. While, growth promoter substances i.e. without (control treatment), water, gibberellic acid "GA3" (100 ppm), oxalic acid "OA" (400 ppm) and yeast extract "YE" (100 ml/L) were distributed on the horizontal plots. The results showed that seed soaking for about 18 hours plus foliar application twice later than 25 and 45 days since sowing of maize with YE (100 ml/200 liter water/fed) in order to obtained high growth, yield and its components under the environmental conditions of Sharkia Governorate, Egypt. }, keywords = {Corn or maize (Zea mays L.),Growth Promoter (GA3),Oxalic acid (OA),Yeast extract (YE),Growth,yields}, url = {https://jpp.journals.ekb.eg/article_40549.html}, eprint = {https://jpp.journals.ekb.eg/article_40549_d57108d7aef312572a4bf281c5de7d74.pdf} } @article { author = {Motawea, M.}, title = {Estimates of Heterosis, Combining Ability and Correlation for Yield and its Components in Bread Wheat}, journal = {Journal of Plant Production}, volume = {8}, number = {7}, pages = {729-737}, year = {2017}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3669}, eissn = {2090-374X}, doi = {10.21608/jpp.2017.40552}, abstract = {In order to realize the heterosis, general and  specific combining ability of wheat, 28 crosses were synthesised in a 8 × 8 by using half diallel mating system, without reciprocals.

The experiment was conducted in 2011–2012 and 2012–2013 seasons at the Experimental Farm of Faculty of Agriculture, Sohag University, Egypt. Heterosis was estimated for grain yield per plant revealed maximum heterosis over the mid parents (68.58% and 81.47%) for the crosses P5 × P8 and P5 × P6, followed by harvest index (53.32%), No. of spikes per plant (33.38%), biological yield per plant (30.71%), spike length (17.29%), 1000 kernel weight (15.13%),grain weight per spike (14.38%) and plant height (5.96%)  for the crosses P7 × P8, P5 × P8, P4 × P5, P4 × P8, P3 × P4, P1 × P3 and P7 × P8, respectively.

General combining abilities were higher than those of specific combining abilities, then the GCA/SCA ratios were more than unity indicating the prepondorance of additive gene effect which have considerable roles in the inheritance of these traits.

Soil survey of the experimental farm was annually done to find the following used salinity levels viz; 2, 6 and 10dSm-1.Giza177, Giza178, Giza179 and Egyptian hybrid one (EHR1) ricevarieties were used.  Anti –oxidants, physio- morphological and growth parameters were measured at heading stage as well as grain yield and yield attributing characteristics were measured at harvest. The obtained results indicated that: increasing salinity levels led up to decreased potassium percentage (K %), increased sodium percentage (Na %) and Na+/K+ ratio in rice plant. Furthermore, increment of salinity levels reduced dry matter accumulation (g),relative water content RWC(%), chlorophyll a,b and total chlorophyll (µg ml-1) and, increased a/b ratio  and antioxidant system peroxidase (POD)(μmol min-1 g-1 protein) Catalase (CAT)(μmol min-1 g-1 protein),proline (mg g-1 FW).Increasing salinity levels decreased the studied growth characteristics; flag leaf area, chlorophyll content (SPAD value), plant height, panicle weight, panicle length, number of filled grains, 1000-grain weight and grain yield/ha-1but increased unfilled grains per panicle. EHR1gave the highest values of most studied characters followed by Giza179 while, Giza178 came in the third order. Giza177 gave the lowest values of the most studied traits. Egyptian hybrid one under the three salinity levels was distinction compared with other rice varieties in both seasons. Based on current biochemical and physiological traits and yield under different salinity levels, the tested rice varieties could be ranked as follows; EHR1>Giza179>Giza178 regarding their salinity tolerance.
