“…Orange and red, >2-fold and >5-fold induction, respectively; blue, >2-fold repression; yellow, no change; gray, no data. maximum carboxylation rate of Rubisco (Fujii et al, 1991;Ramraj et al, 1997;Yu et al, 2004), and our results suggest that BR levels that are elevated by transgenes can have similar effects. Although it is not clear how BRs bring about these effects on photosynthesis, the repression of the U-box ubiquitin ligase (and the possible repression of the chloroplast protease) that were conspicuous in the microarray data might have prolonged the half-lives of some of the photosynthetic proteins, and the induction of the Rubisco small subunit might have increased the capacity for carboxylation and the accumulation of sucrose.…”

Genes controlling hormone levels have been used to increase grain yields in wheat (Triticum aestivum) and rice (Oryza sativa). We created transgenic rice plants expressing maize (Zea mays), rice, or Arabidopsis thaliana genes encoding sterol C-22 hydroxylases that control brassinosteroid (BR) hormone levels using a promoter that is active in only the stems, leaves, and roots. The transgenic plants produced more tillers and more seed than wild-type plants. The seed were heavier as well, especially the seed at the bases of the spikes that fill the least. These phenotypic changes brought about 15 to 44% increases in grain yield per plant relative to wild-type plants in greenhouse and field trials. Expression of the Arabidopsis C-22 hydroxylase in the embryos or endosperms themselves had no apparent effect on seed weight. These results suggested that BRs stimulate the flow of assimilate from the source to the sink. Microarray and photosynthesis analysis of transgenic plants revealed evidence of enhanced CO 2 assimilation, enlarged glucose pools in the flag leaves, and increased assimilation of glucose to starch in the seed. These results further suggested that BRs stimulate the flow of assimilate. Plants have not been bred directly for seed filling traits, suggesting that genes that control seed filling could be used to further increase grain yield in crop plants.

“…The morphological parameters like plant height, leaf area increased significantly (P < 0.05) with sprays and dosage of brassinolide compared to control and root irrigation (Figures 1 and 2). Similar result was reported by Ramraj et al (1997). Plants sprayed with brassinolide reached the reproductive stage earlier than plants which were not sprayed with brassinolide.…”

The present study shows the effect of the foliar and root application of brassinolide on growth and metabolism of Vigna radiata. For this purpose, three concentrations of brassinolide (1, 0.01 and 0.0001 ppm) were applied on the plant. Brassinolide (BL) solutions were applied as foliar and root treatments for 21 days after sowing (DAS). Samples were collected after two and four weeks of treatments. Content of total sugars, reducing sugars, chlorophyll and proteins, activity of peroxidase (EC 1.11.1x), leaf area and height of plants were estimated. All these parameters increased significantly by 1 ppm foliar spray of BL as compared to the other concentrations. It was concluded that BL enhanced growth of V. radiata. L. under both root and foliar applications, but foliar treatment was more effective.

“…Many authors concluded that some vitamins, as antioxidant materials had positive effects on the growth, yield and oil production such as Ramraj et al (1997) on mustard, Refaat and Balbaa (2001) on lemongrass, Ismail (2008) Production of medicinal and aromatic plants using biofertilizers and natural substances became an essential process to ensure the safety, not only for human, but also for the environment in which we live. Therefore, it would be beneficial to use alternatives to chemical fertilizers.…”

ABSTRACT:Two field experiments were carried out during 2013/2014 and 2014/2015 seasons at the Experimental Farm, Fac. Agric., Minia Univ. to investigate the effect of compost (0, 5, 7.5 and 10 ton/fed), mineral NPK, effective microorganisms (E.M.), vit. E, vit. B 1 , E.M. + vit. E. and E.M. + vit. B 1 on the growth and productivity (fruits and essential oil) of coriander plants.The obtained data revealed that vegetative growth characters (plant height, stem diameter and herb dry weight/plant), yield components (number of umbels/plant, fruit yield/plant and /fed) and all studied oil production (oil %, oil yield/plant and /fed) were significantly increased due to the application of all levels of compost over those of control treatments. The maximum values were recorded at the high level of compost (10 ton/fed). Vegetative growth characters, fruit yield and essential oil productivity parameters were significantly augmented as a result of using the different six treatments. The most effective treatments in this concern were mineral NPK (full dose) followed by E.M. + vit. E without significant difference between such superior treatments.While, E.M. plus either vit. E or vit. B 1 gave the highest essential oil %. Moreover, E.M. + vit. E followed by NPK (full dose) recorded the highest essential oil yield/plant and /fed.It could be recommended to supply Coriandrum sativum plants with compost at 10 ton/fed in combination with E.M. + vit. E. to alternative to compost (10 ton/fed) with mineral NPK (full dose) to ensure the safety, not only for human but also for the environment in which we live.
