“…However, subjecting plants to water stress at flowering stage caused the highest reduction in all growth parameters in the two seasons. The adverse effect of drought stress on growth roselle parameter may be attributed to the decrease in net photosynthetic rates (photo inhibition) in Plants due to stomatal closure, which decreases or prevents water loss but reduces CO 2 availability for chloroplast , Bertamini, et al (2007). These results were agreed with those reported by El-Boraie et al (2009) on roselle plant.…”

Water considers the most important component of life, it is rapidly becoming a critically short commodity for humans and crop production. Drought is one of the major a biotic stresses in agriculture worldwide. In order to study the effect of water stress (skipping one irrigation at vegetative, flowering and fruits formation growth stages) in comparison with traditional irrigation in addition to foliar application of chelated iron , zinc , manganese and their combination on growth , productivity of dark roselle (Hibiscus sabdariffa, L.) plants and some water relations under surface irrigation system. Two field experiments were conducted at the Experimental Farm of Sakha Horticulture Research Station, Kafr El-Sheikh Governorate during the summer seasons of 2014 and 2015. The results revealed that skipping one irrigation at any of the three studied stages significantly reduced all the tested growth parameters and yield production as compared with unstressed plants (control). However, subjecting roselle plants to water stress at flowering stage had the most negative effect on growth parameters and yield production. On the other hand, water stress had a stimulating effect on chemical composition (total anthocyanin, T.S.S, acidity%, pH and T.S.S acidity ratio). The present study also indicated that foliar application of chelated Fe ,Zn, Mn and combination among them had a positive effect on growth parameters, yield and chemical composition but chelated Zn application surpassed the other nutrients in counteracted the deleterious effects of stress on chemical composition. Application of chelated Fe+ Zn + Mn showed the significant increasing in calyxes yield/fed, fibers yield/fed and seeds yield/fed. Also, the highest overall mean values for seasonal amount of water applied, consumptive use, water productivity and productivity of irrigation water for all plant organs were recorded under traditional irrigation. Meanwhile, the lowest overall mean values were recorded under water stress treatments and the amount of water saving is 8.89%. Concerning, micronutrients as foliar application, the highest overall mean values were recorded under application of chelated (Fe+Zn+Mn) in comparison with non-application and application every nutrient as alone. Regarding, consumptive use efficiency, the highest mean values were recorded under skipping one irrigation at vegetative growth Nahed, M. Rashed and E.A. Moursi 2 stage, but the lowest were recorded under traditional irrigation. Also, the highest values were recorded under foliar application treatment (Fe+Zn+Mn) comparing with non-application and application every nutrient as alone .This study can be concluded that skipping one irrigation at vegetative growth stage when cultivated roselle plants under studying region with chelated (Fe+ Zn+ Mn) foliar application which counteracted the deleterious effects of stress and chelated Zn foliar application only to increase chemical component .Nevertheless, reduction in yield offset saving nearly 9% of water applied.

“…The F v /F m in drought-treated leaves of Kelleris 16 was 0.38, which is much below the considered boundary value (0.75) for fully functional PSII (BOLHÁR-NORDENKAMPF et al 1989). A reduction of F v /F m in drought stress was reported by many authors (BAUERLE et al 2003, BERTAMINI et al 2007). Performance index (PI ABS ) was decreased in drought-treated leaves of both investigated genotypes (Fig.…”

-Drought is a limiting factor in fruit production today. Identification of sour cherry genotypes tolerant to drought will enable the sustainability of fruit production. The aim of our study was to select sour cherry genotypes according to their genetic background as well as drought tolerance and investigate possible mechanisms of drought tolerance through the changes in photosynthetic apparatus (i.e. photosynthetic pigment content) and photosynthesis process assessed through the chlorophyll fluorescence transient. All of them together with molecular markers (SSRs and AFLPs), relative water content (RWC) as indicator of plant water status distinguish two genotypes (Kelleris 16 and OS), which are the opposite in regards to drought tolerance. Down-regulation of photosynthesis in drought-treated Kelleris 16 plants was seen as changes in antenna complexes of PSII (decreased total chlorophylls content (a+b) and chlorophylls ratio (a/b)). Despite unchanged maximum quantum yield of PSII in drought-treated leaves of genotype OS, overall photosynthetic performance expressed as PI ABS was down-regulated in both investigated genotypes. However, decrement of PI ABS was much pronounced in genotype Kelleris 16, mainly because of changes in a certain fraction of RCs, which become dissipative centres, seen as increase in ABS/RC and DI 0 /RC, in order to avoid photooxidative damage of photosynthetic apparatus. Also, electron transport, seen as decrease in ET 0 /(TR 0 -ET 0 ) and ET 0 /RC, was impaired which lead to impaired CO 2 fixation and photosynthesis. The described changes in the functioning of photosynthetic apparatus in drought-treated plants of Kelleris 16 constitute the main distinction between the two investigated genotypes regarding drought adaptation mechanisms.

“…Some authors report that shading has little effect on berry ripening and sugar accumulation but increases the pH and titratable acidity of the must (Ristic et al, 2007 ;Matus et al, 2009). Others have found that shaded berries ripen later and have a lower total soluble content (Bertamini et al, 2007 ;Marta et al, 2008 ;Abd El-Razek et al, 2010). Greer and Weedon (2012) found that irradiance, irrespective of seasonal temperatures, has no effect on the timing of budbreak nor on shoot phenology, stem growth or yield.…”

Aim: To test the hypothesis that shading of the fruiting zone of the plants might reduce yield losses caused by excessive exposure to sun while avoiding the most damaging effects associated with reduced radiation.Methods and results: A number of grapevine rows were shaded with a double layered white plastic netting on their south-facing side, from the ground to about 20 cm above the cluster zone. Data on meteorological conditions, plant growth, plant water availability, yield components and must characteristics were recorded during three growing seasons. Shading significantly increased yield but did not alter significantly the must characteristics.Conclusion: Partial shading of the grapevine canopy reduced yield losses attributable to excessive radiation. The must obtained from shaded berries had a lower concentration of anthocyanins, and the wines made from these musts had a lighter colour which may be detrimental to their quality.Significance and impact of the study: The study highlights the effects of solar radiation on the composition of grape musts and suggests a potentially cost-effective method to control excessive radiation in vineyards.
