Growth and Molecular Expression of Okra Seeds Interacted with Fourteen Mango Cultivars in Mixed Cropping System

Abstract

The present study was accomplished to study the effect of fourteen cultivars (Keitt, Ewais, White Succari, Tommy Atkins, Fajri Klan, Zebda, Alphonso, Sedeek, Naomi, Mesk, Baladi Dabsha, Baladi Arnaba, Cobania and Totapuri) of Mangifera indica L. leaves aqueous extracts (MILAE) on germination and some growth parameters as well as seedling protein profile of Hibiscus esculentus L. (okra seeds) in mixed cropping system. The study was extented to characterize and discriminate among the aforementioned cultivars. The allelopathic potential of fourteen cultivars of M. indica leaves aqueous extracts (MILAE) on germination efficiency and growth parameters of H. esculantus L. seeds (as a recipient bioassay material) was completely studied. Hypocotyl length (HL) was more sensitive than radicle length (RL) for all studied cultivars. At the all concentrations level, Mesk cultivar exerted the highest allelopathic effect, while Totapuri cultivar showed the lowest one on the germination percentage (GP), inhibition percentage (IP), the time to get 50% germination (T 50 ), mean germination time (MGT), germination energy (GE), seed germination index (SGI), emergence percentage (EP), mean emergence time (MET), seedling emergence index (EI), seedling vigour index (SVI), hypocotyl (HL) and radicle (RL) lengths, seedling fresh (SFW) and dry (SDW) weights.Seedling protein electrophoresis data revealed that Tommy Atkins cultivar attained the minimum values for both the number of bands and the percentage of polymorphism, 6 bands and 27%, respectively. On the other hand, the maximum values were achieved from both Naomi and Totapuri cultivars, 11 bands and 51%. Reversibly, the genomic template stability (GTS %) oscillated from 32% in Cobania cultivar to 64% in specimen Tommy Atkins cultivar. The resulted dendrograms by using allelopathic and molecular data as well as seedling protein electophoresis ascertains three aggregations. The first assembly includes Sedeek, Naomi and Mesk cultivars. The second gathers Keitt and Ewais cultivars. While, the third clusters Fajri Klan, Zebda and Alphonso cultivars.

Intercropping with the potential cadmium hyperaccumulator Solanum photeinocarpum, and its post‐grafting generations, decrease cadmium uptake and promote growth of cherry

“…Additionally, the intercropped shoot biomass of S. photeinocarpum and its post‐grafting generations was linearly positively related to their monoculture shoot biomass, and intercropped shoot biomass of cherry seedling was also linearly positively related to the monoculture shoot biomass of S. photeinocarpum and its post‐grafting generations. These results indicate that intercropping linearly affects the biomass of the two plants, and is consistent with previous studies 33,34 . Therefore, intercropping with S. photeinocarpum and its post‐grafting generations can promote the growth of cherry.…”

Comparative Study on Fruit Yield and Quality Traits of the New Mango Cultivars Grown Under Egypt Conditions

“…According to the latest statistics from the Economic Agricultural Affairs Sector of the Ministry of Agriculture and Land Reclamation in 2020, the mango cultivated area of Egypt reached 125,460 ha, and 112,905 ha showed fruitful producing about 1,203,743 t of fruits, with an average of 1.811 t h .-1 . Mango production concentrates in the regions of El-Sharkia, El-Giza, El-Ismailia, EL-Fayoum, and El-Behera (Nubariya) (Abourayya et al, 2011;Marzouk et al, 2017).…”

Differential Responses of Hordeum vulgare L. to Allelochemicals of Some Olea europaea L.Cultivars

“…This interaction plays an important role in crop productivity, conservation of genetic diversity, mainten-ance of ecosystems stability. These beside the strongly link with some environmental stresses (extreme temperature and radiation, nutrient deficit, insects, diseases and herbicides) and vegetation interaction in poly culture practices (Marzouk et al, 2017). Also, this interaction is a safe alternative use to endure developpment in sustainable agriculture and to leave a clean environment for future generations.…”
