ترجمة الملخص

The research address the study of E. that suffers from ovules abortion, and forming empty fruits, where it,s flower is characterized as , thus creating a chance of self incompatibility. And H. does n,t suffers ovules abortion and has full fruits that contains seeds. The technique of culture in vitro using media contains sugar and phytohormones in a single or mixed form showed it role in the evolution of floral buds extracted from maternal plant and in vitro in addition to the possibility of producing mature pollen grains. The medium (MS+ Sugar 50 g/l +BAP-1 +GA3-3 mg/l) at E. and medium (MS+ Sugar 50 g/l +Kin-3 +IAA-1 mg/l) at H. gave the best result after 4 days of planting. The study of cellular chemical showed an increase in starchy savings and lipids for pollen grains taken from floral buds cultivated on the best medium containing the previous hormonal mix of the two studied species. The experiments we did on pollen germination allowed us to notice the effect of sucrose, temperature, boron, calcium and pH in the percentage of germination in pollen tubes growth. Where we are able to improve the low pollen germination rate of the species E. by using the best culture medium used in producing mature pollen grains with the best pollen germination medium. Where the medium (MS + Sugar 50g/l + BAP-1 +GA3-3mg/l) with the germination medium (Sugar 220g/l + Boron 300mg/l +Ca 400mg/l + PH=6 + T=25) gave the best result after 4 hours of planting. We studied the effect of different concentration of hormone in seeds germination rate and length of root and stem, where the medium (MS + GA31mg/l) gave the best result of the two studied species. some seedlings resulting from the best medium were planted in pots contains to adapting them with outside, and then surviving their growth until maturity after month
