The development of aeroponic cultivation technology has led to more efficient use of water and plant nutrients for producing high quality agricultural commodities. In this research, cucumbers were grown in columnar aeroponic systems for nine weeks and the effect of spraying rate and spraying duration on the cucumber average yield and water usage efficiency were investigated. The experiments were performed using factorial experiment based on completely randomized designs. The spraying rate had three levels of 125, 250 and 375 mL/min, and the spraying durations were 10, 15 and 20 min. During the experiment, the spraying pumps were turned off for 15 min between each spraying time. Then, the two factors were simultaneously optimized using response surface methodology to maximize fruit yield and water usage efficiency. The ANOVA results showed that both responses were significantly affected by the main effects of the factors (α = 0.01) and by their interaction effects (α = 0.05). The comparison of first and second-order models to show the average yield and water usage efficiency as functions of sparing rate and sparing time indicated that the second-order models fitted with higher accuracies (R2> 80%) to the experimental data than the first-order model. Simultaneous optimization showed that the most suitable spraying rate was 233.37 mL/min and for the spraying duration, it was 16.06 min. At the optimum conditions, the average yield per plant yield was 2.96 kg and the water usage efficiency was 110.37 kg/m3.

Achillea moschata Wulfen (Asteraceae) is an endemic species growing on the Alps and traditionally used in several medicinal remedies. For its aromatic properties, it is also collected for food purposes. Chemical content and biological activity of A. moschata oil are not extensively studied. We investigated whether the different lithological and geomorphological features of two alpine areas including Vallone dello Scerscen and Valle dei Ratti, located in the Sondrio Province (Northern Italy), can influence the essential oil (EO) composition and the related antioxidant activity of the respective A. moschata populations. The essential oils obtained by steam distillation from the dried aerial parts were investigated by GC/FID and GC/MS. Several compounds were identified belonging to different chemical classes, including monoterpenes and sesquiterpenes as the most abundant constituents, together with ketones, alcohols, phenols, acids and esters. A variation in the quantitative composition of several constituents was recorded in the two oils. The main constituents were camphor (23.4-34.2%), 1,8-cineole (9.8-16.4%), trans-tujone (3.6-13.4%), sesquicineole (3.5-5.8%), borneol (1.1-4.8%), -caryophyllene (2.7-4.4%) and myrcene (1.3-4.2%). Their antioxidant activity was measured in vitro by the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS⋅+) and 2,2-diphenyl-picryl hydrazyl (DPPH⋅) stable radical assays. The essential oils showed similar and significant scavenger effects, possibly due to the synergistic action of all components including compounds present in small quantities.
阿喀琉斯武芬(菊科)是一种生长在阿尔卑斯山的特有物种，传统上用于几种药物治疗。由于其芳香的特性，它也被收集作食品用途。目前对香柳油的化学成分和生物活性研究较少。研究了位于意大利北部桑德里奥省(Sondrio Province)的两个高山地区(Vallone dello Scerscen和Valle dei Ratti)的不同岩性和地貌特征是否会影响莫夏塔(A. moschata)种群的精油成分和相关抗氧化活性。采用气相色谱/FID和气相色谱/质谱联用技术对干燥的空气部分进行水蒸气蒸馏法提取的精油进行了研究。几种化合物被鉴定属于不同的化学类别，包括单萜烯和倍半萜烯作为最丰富的成分，以及酮、醇、酚、酸和酯。在两种油中记录了几种成分的定量组成的变化。主要成分为樟脑(23.4-34.2%)、1,8-桉树脑(9.8-16.4%)、反式杜仲酮(3.6-13.4%)、倍松香脑(3.5-5.8%)、冰片(1.1-4.8%)、-石竹烯(2.7-4.4%)和月桂烯(1.3-4.2%)。采用2,2′-氮基-双(3-乙基苯并噻唑-6-磺酸)(ABTS⋅+)和2,2-二苯基-癸酰肼(DPPH⋅)稳定自由基法测定其体外抗氧化活性。这些精油显示出相似且显著的清除作用，可能是由于所有成分的协同作用，包括少量存在的化合物。

In two independent experiments, acclimatized chicory plants were transferred into an aeroponic system and to the soil. Then, the effects of biofertilizer (Nitrokara) and culture filtrate of Piriformospora indica were investigated on some plant characteristics in both aeroponic and soil cultivation system under greenhouse conditions. The plants were foliar sprayed with three different biofertilizer concentrations (1, 2, and 3 g/L) and P. indica culture filtrate (2.5, 5, and 7.5 mL in 100 mL water) following 20, 40 and 60 days after transplanting to the aeroponic and soil culture media. Results showed that the highest vegetative growth (e.g. plant height, root length, number of leaves per plant, root and shoot dry weights) and physiological traits (e.g. relative water content, proline, anthocyanin content, chlorophyll a, and chlorophyll b) were observed with 7.5 mL of P. indica culture filtrate in both aeroponic and soil culture media. Besides, the best results for all studied traits were obtained from 3 g/L of biofertilizer application in the both culture media. In both experiments, better results were obtained from the aeroponic system than the soil culture for P. indica production.

Production of high quality seeds in African leafy vegetables has not been practiced due to varying reasons including incorrect harvesting stages and fertilizer rates. Jute mallow (Corchorus olitorius L.) pods do not ripen simultaneously and fruits left to dry on mother plant long before harvesting, which face seed quality deterioration. Timely seed harvesting ensures maximum seed quality attributes of purity, germination and vigour. The present study aimed to investigate the effects of harvesting stages and nitrogen fertilizer on seed quality and yield of Jute mallow. Seed samples from four Jute mallow morphotypes (GEMS, GLMT, BEMS, and BLMT) were planted. Completely randomized block design was used for analysing the effects of nitrogen fertilizer levels (0, 60 and 120 kg/ha) with three replicates. Five plants were randomly tagged per plot and seed harvested at three maturity stages of green, tan and black. Seed quality test of purity, germination and vigour were done as per ISTA (2004) and means separation done by DMRT at p≤0.05. Results showed that harvesting stage significantly influenced seed quality attributes, in a way that the maximum purity, germination and seed vigour was detected at tan pod stage and their lowest levels were observed at black pod stage. It can be concluded that best agronomic practices of Jute mallow seed can be attained when they harvested at tan stage together with use of N fertilizer for high seed quality and yield.

Some cultivars of grapevine have very compact cluster which adversely affect its quality and marketability. ‘Yaghouti’ is a commercial early table grape cultivar that has very compact clusters. The present study was conducted to assess the effects of mechanical and chemical thinning as well as GA3 application on cluster morphology and berry size of grapevine cv. ‘Yaghouti’. Treatments were chemical thinning agents including: NAA (7.5 and 15 mg/L), Ethephon (75 and 150 mg/L), Sevin (750 and 1500 mg/L) and mechanical thinning by a comb (comb thinning), applied a week after fruit set and unthinned clusters as control with 3 replications, 10 days after thinning, clusters were immersed in GA3 solution at 60 mg/L. Results indicated that berry numbers were reduced in all thinning treatments. Length, width and weight of berries increased significantly when treated with hand or chemical thinning. GA3 alone and Sevin at 750 mg/L in combination with GA3 treatment improved yield and the quality of berries. Total phenolics compounds, TSS and berries colour were improved in all thinning treatments. In general, application of Sevin at 750 mg/L combined with GA3 and hand thinning along with GA3 are proposed to improve quality of grapevine berries.

Licorice (Glycyrrhiza glabra L.) as a strategic and highly valuable medicinal plant in Iran with numerous beneficial pharmaceutical properties contributes substantially to Iranian herbs exports. In the present study, a variation on the phytochemical and antioxidant activity of 25 populations of valuable and profitable medicinal plant of G. glabra was investigated. The climate variables and soil properties were evaluated in various habitates of G. glabra. Total phenol (Folin–Ciocalteu method), total flavonoid (Aluminum Chloride method), anthocyanin (pH difference method) and antioxidant activity (DPPH method) were studied. Glycyrrhizic acid, glabridin, liquiritigenin and liquiritin content of root were evaluated by liquid chromatography. The content of major components in G. glabra varied in different regions. Outstanding quantitative variability of glycyrrhizic acid, glabridin, liquiritin and liquiritigenin content were observed in roots of licorice from different regions of Iran. Glycyrrhizic acid content was varied from 93.89 (mg/g dry weight) for the Sepidan population to 20.68 (mg/g dry weight) for the Ahar population. The maximum and minimum amounts of glabridin were recorded in Kashmar and Bajgah populations, respectively. The highest levels of liquritin and liquiritigenin were in the population of Kazerun and Yasuj, respectively, and the lowest was observed in Kashmar. Also, the highest antioxidant activity (the lowest IC50) for licorice root was associated with Semirom population. In conclusion, The populations with high amount of each active ingredient in licorice root and those with considerable antioxidant activity can be exploited depending on the purpose of breeding and cultivation.

Investigating genetic diversity in plant species provides a platform for further insight in plant breeding and conservation. Therefore, in the present study genetic diversity of 13 geographically isolated genotypes of Zhumeria majdea, as a seriously endangered medicine plant growing exclusively in Hormozgan province (South of Iran) was studied. To do so, the leaf samples of Z. majdea were collected from the main growing habitats of this spices including Haji Abad, Geno and Bastak regions. The collected leaf samples were subjected to DNA extraction followed by PCR assay, using Inter-Simple Sequence Repeats (ISSR) markers. Twelve markers produced totally 121 polymorphic bands and revealed a clear-cut among and within Z. majdea genotypes. The analysis of molecular variance (AMOVA) showed 86% and 14% variations within and among populations, respectively. Cluster analysis divided genotypes into four main groups. The first and second principle coordinates allocated 28.81% and 15.71% of the variations, respectively. In addition to the innate differences of the individuals, the high intra population variation of Z. majdea, can also be explained by differences in the presence or absence of endophytes and differences in the type and genetic pattern of their endophytes.

Tomato (Lycopersicon esculentum) is an important member of the Solanaceae family. It is mainly used as food and cash crop globally. Tomato also serves as an ornamental plant in some parts of the world. In urban areas, this crop is included in the foodscaping systems where it is grown in hanging baskets, growing pots and aquaponics for aesthetic and food purposes. Tomato production is mainly done for fresh and processing market niches. Most developed countries process a larger portion of tomato than is offered in fresh form. Cultivation of tomato is practiced on the open field and inside greenhouses. Greenhouse production has gained popularity recently. Determinate varieties are produced outdoor while indeterminate ones are produced in greenhouses and tunnels. Due to good adaptability, heirloom tomato varieties are becoming popular especially where farmers practice tomato grafting using the indigenous varieties as rootstocks. High cost of inputs, pest and diseases, postharvest losses and marketing are the major challenges facing tomato production globally. Organic tomato production is an emerging market niche. This is due to the increased consumer awareness, environmental conservation requirements and globalization. Thus, farmers have been making strides towards compliance to organic and other sustainable standards. These standards require adoption of the requisite practices, documentation, verification and certification by a third party. Value addition in tomato is an important aspect in addressing the postharvest challenges, product diversification and ultimately profitability. This review paper is expected to provide the requisite information in tomato value chain to ensure sustainable production of tomato globally.

Fusarium wilt is one of the most destructive diseases of muskmelon (Cucumis melo L.), which is an economically important disease worldwide causes yield losses in muskmelon growing areas. One of the most effective controlling measures to prevent Fusarium wilt is through host resistance by using resistance genes. We used developed molecular markers for Fom-2 gene, which confers resistance to race 1 of Fusarium in muskmelon, to screen muskmelon landraces in Khorasane-e-Razavi, Iran. After validation of the markers on a differential set of resistant and susceptible lines, we identified STS312 marker as the polymorphic and easy-to-score marker. Then we used STS312 to genotype plants from five different landraces. Our results suggest that resistance allele of Fom-2 gene is present in two landraces: Eyvankey and Mashhadi. These landraces can be used by muskmelon breeders to enhance resistance to Fusarium wilt in muskmelon.
