“…This result is consistent with other findings (Jiang and Huang 2002). Also, Heidari and Karami (2013) reported increase in protein content of sunflower under a moisture stressed condition. The reason for increasing the protein percentage by drought stress is osmo-regulation and water absorption phenomena (Cellier et al, 1998).…”

An experiment was conducted at the Experimental Farm of Sakha Agricultural Research Station 31° 07\\ N and 30° 57\\, Kafr El-Sheikh, Egypt, during 2015 and 2016 seasons to study the effect of skipping one irrigation at different growth stages and foliar application of zinc on quantitative and qualitative characteristics of sunflower cultivar Sakha 53.A split plot design with four replications was used. The main plots were devoted to water treatments i.e. I 1 = without skipping (control four irrigation during season), I 2 = skipping one irrigation during vegetative stage, I 3 =skipping one irrigation during flowering stage, I 4 = skipping one irrigation during grain filling stage. Sub plot treatments were devoted to foliar application with zinc sulfate , i.e. Zn o = water application, Zn 1 = 0.5% and Zn 2 = 1% concentration. The results showed that flowering stage was the most sensitive to water deficit stress and skipping irrigation at this stage caused marked decrease in chlorophyll content in leaves, relative water content (RWC %), seed oil %, seed yield and its components, while increased proline content and seed protein % in the two growing seasons. Zinc spraying had significant effect on all attributes in this research. In general, application of Zn could be used as a good tool to increase yield of sunflower under drought stress.Also, the highest mean values for seasonal amount of water applied and water productivity were recorded under traditional irrigation. From this study we can be concluded that it is possible to gain high seed yield with less quantities of applied water when the irrigation skipping happens at vegetative stage with application of 1% zinc sulfate .

“…The range of all chemicals can vary greatly as a result of growing conditions, such as in response to the application of biostimulants [63]. Inoculation with AMF is known to alter the production of secondary metabolites in MAPs, both in roots, shoots, and flowers, even if is not consistent among plant organs [66]. The effects of AMF inocula on the biosynthesis of secondary metabolites in saffron are presented in Table 3.…”

Saffron (Crocus sativus L.) is cultivated worldwide. Its stigmas represent the highest-priced spice and contain bioactive compounds beneficial for human health. Saffron cultivation commonly occurs in open field, and spice yield can vary greatly, from 0.15 to 1.5 g m−2, based on several agronomic and climatic factors. In this study, we evaluated saffron cultivation in soilless systems, where plants can benefit from a wealth of nutrients without competition with pathogens or stresses related to nutrient-soil interaction. In addition, as plant nutrient and water uptake can be enhanced by the symbiosis with arbuscular mycorrhizal fungi (AMF), we also tested two inocula: a single species (Rhizophagus intraradices) or a mixture of R. intraradices and Funneliformis mosseae. After one cultivation cycle, we evaluated the spice yield, quality (ISO category), antioxidant activity, and bioactive compound contents of saffron produced in soilless systems and the effect of the applied AMF inocula. Spice yield in soilless systems (0.55 g m−2) was on average with that produced in open field, while presented a superior content of several health-promoting compounds, such as polyphenols, anthocyanins, vitamin C, and elevated antioxidant activity. The AMF symbiosis with saffron roots was verified by light and transmission electron microscopy. Inoculated corms showed larger replacement corms (+50% ca.). Corms inoculated with R. intraradices performed better than those inoculated with the mix in terms of spice quality (+90% ca.) and antioxidant activity (+88% ca.). Conversely, the mixture of R. intraradices and F. mosseae increased the polyphenol content (+343% ca.). Thus, soilless systems appeared as an effective alternative cultivation strategy for the production of high quality saffron. Further benefits can be obtained by the application of targeted AMF-based biostimulants.

“…Inoculation of plants grown under water stress resulted in a significant increase of water use efficiency. Heidari and Karami (2014) on sunflower using water stress treatment (W1=90,W2 =70 and W3=50 % of field capacity) and two different mycorrhiza species, mentioned that by increasing water stress from control (W1) to (W3) treatment, the content of potassium in seeds significantly decreased due to water stress but water stress up to W2 treatment increased the content of phosphorus, nitrogen and oil content of seeds. These results are in agreement with those obtained by Eisa (2004) on sage.…”

The present work was carried out at a private Farm in Sammenoud area, Gharbieh Governorate during the two successive seasons of 2011-2012 and 2012-2013. The present study aimed to investigate the effect of bio fertilizers (VAM fungi and phosphorine) and foliar spray of plant extracts (garlic and aloe) on some vegetative growth (plant height, fresh and dry weight) essential oil percentage and chemical constituents of sage (Salvia officinalis L.) plant under different water stress conditions (plants irrigated every 15, 30 and 45 days). The results showed that irrigation of plants every 15 and 30 days were effective in increasing the productivity of vegetative growth, essential oil percentage and uptake of N,P and K % in sage. Spraying plants with garlic extract was more effective than aloe extract at in improving the productivity of vegetative growth, essential oil percentage and uptake of N, P and K content. Plants treated with VAM fungi were effective in increasing the productivity of vegetative growth, essential oil percentage and uptake of N, P and K %.
