“…The increase in essential oil due to zinc and /or iron was also reported in Japanese mint (Misra and Sharma, 1991), cumin (El-Sawi and Mohamed, 2002), peppermint (Akhtar et al, 2009) and sweet basil (Said-Al Ahl and Mahmoud, 2010) and chamomile (Nasiri et al, 2010).…”

In order to study the effects of soil and foliar applications of iron (Fe) and zinc (Zn) on flowering, flower yield and essential oil production of German chamomile a pot experiment was conducted under greenhouse conditions at the Faculty of Agriculture, University of Tabriz, Iran in 2012. The experiment was arranged as completely randomized design with 12 treatments and three replications. ), T 9 : T 5 +T 7 , T 10 : T 5 +T 8 , T 11 : T 6 +T 7 , T 12 : T 6 +T 8 . The foliar spraying was done two times during the growing period. The results revealed that the flower number, flower yield, essential oil content and essential oil yield were significantly increased by soil and foliar applications of Fe + Zn, compared with the control (untreated). The highest flower number (477 plant -1 ), flower yield (11.6 g pot -1 ), essential oil content (0.88 %) and essential oil yield (119 mg pot -1 ) were recorded for the soil application of Fe + Zn (T 4 ) by 58, 68, 21.4 and 105 % increment compared to the control, respectively. Foliar application of Fe + Zn (T 12 ) was placed at the next rank; however this treatment had no significant difference with the soil application of Fe + Zn (T 4 ). Other treatments did not show significant differences with the control. Generally, the results showed that soil or foliar application of Fe + Zn can be effective on increase or improve of quantity and quality of chamomile yield. Moreover, use of foliar application as a low cost method especially in areas with alkaline or calcareous soils can be recommended. ), T 9 : T 5 +T 7 , T 10 : T 5 +T 8 , T 11 : T 6 +T 7 , T 12 : T 6 +T 8 . Škropljenje listov je bilo opravljeno dvakrat v rastni dobi. Rezultati so pokazali, da je talno in foliarno gnojenje z Fe + Zn značilno povečalo število cvetov, pridelek cvetov, vsebnost in pridelek eteričnih olj v primerjavi s kontrolo. Največje število cvetov (477 na rastlino), največji pridelek cvetov (11.6 g na lonec), največja vsebnost eteričnih olj (0.88 %) in največji pridelek eteričnih olj (119 mg na lonec) so bili izmerjeni pri talnem dodajanju Fe + Zn (T 4 ), povečanje je bilo za 58, 68, 21.4 in 105 % glede na kontrolno obravnavanje. Učinek foliarnega dodajanja Fe + Zn (T 12 ) je bil takoj za talnim dodajanjem Fe + Zn (T 4 ), vendar se od njega ni značilno razlikoval. Druga obravnavanja niso dala značilnih odstopanj od kontrole. V splošnem so rezultati pokazali, da lahko tako talno kot foliarno dodajanje Fe + Zn učinkovito poveča ali izboljša količino in kvaliteto pridelka prave kamilice. Uporabo foliarnega dodajanja bi kot poceni način gnojenja še posebej priporočali na območjih , kjer so tla bazična ali apnenčasta.

“…Zn is involved in carbon assimilation, saccharide accumulation, free radical removal, antioxidant enzymes, carbon utilization in terpene biosynthesis, and the overall growth of the plants. The requirement of Zn for Japanese mint and its limitations imposed on photosynthetic carbon metabolism and translocation in relation to essential oil accumulation in mint were shown by Misra and Sharma (1991), whereas antioxidant enzymes for free radical quenching in geranium have not been fully documented.…”

“…Leaf fresh and shoot dry mass and area (area meter Li-3000) were also recorded. For tissue element analysis 1 g dried leaf samples were digested with 1 M HCl at 60 °C for 24 h. Aliquot samples of the clear digest were diluted with water (10 cm 3 ) and analyzed for Zn by atomic absorption spectrophotometer (Pye Unicam SP 2800) (Misra and Sharma 1991). Antioxidant-reactive peroxidase enzyme activity was estimated as described in Sharon et al (1960).…”

Culturing geranium at different doses of Zn from 0-1.0 g m -3 (Zn 0 to Zn 1.000 ) revealed that Zn is an antioxidant promoter, apart from its micronutrient essentiality. Zn 0.250 was the critical concentration for maximum content (0.21 %) of total essential monoterpene oil(s). At Zn 0.005 -Zn 0.250 , net photosynthetic rate, and contents of chlorophyll and essential monoterpene oil(s) were affected. The maximum peroxidase activity was obtained at Zn 0.250 , with the production of biomolecule geraniol. We found an oxido-reducible reaction of Zn in the formation of monoterpene essential oil(s) and possibly major constituents of geraniol.

Genotypic variations were observed among 6 variants and an indigenous one as a control. An efficient genotype OCD(L) of Ocimum sanctum had the greatest content of chlorophylls [2.15 g kg −1 (FM)], Chl a/b ratio of 1.86, net photosynthetic rate of 0.72 mg(CO 2 ) m −2 s −1 , and 1.56 % oil formation. Methyl chavicol formed 50.31 % of total oil in OSP-6 genotype, which had also maximum peroxidase activity [ΔOD 2.4 mg −1 (protein)] and maximum production of eugenol (30.44 % of total oil). We found an oxido-reducible reaction of peroxidase and high bands of peroxidase isoenzymes in this OSP-6 genotype for the formation of monoterpene essential oil(s) and possibly the major constituents of eugenol through the high production of photosynthates.
