Global climate change minimizes fresh water resources used in agriculture worldwide. It causes drought stress, which has adverse effects on plants. To ensure food security, crops and vegetables capable of tolerating shortages over the growth period are needed. This study aimed to elucidate morphological biochemical responses three colored cauliflower (Brassica oleracea var. botrytis) cultivars (Clapton, Trevi, Di Sicilia Violetto) one broccoli cultivar italica Magic) different irrigation...

Diversity among Iranian melon landraces of Groups Flexuosus and Dudaim was studied by analyzing morphological physiological traits random amplified polymorphic DNA (RAPD). Thirty-one showed significant variation accessions. Some accessions had typical characters elongated fruit shape, light skin color, ribs on non-sweet flesh. Characters distinct from in accessions, such as short fruits, dark green five carpels, sweet flesh, were especially ribless Cluster analysis divided into seven groups....

Nowadays the importance of selenium for human health is widely known, but most plants are poor in terms storage and accumulation because low mineralization potential soil. For this purpose, foliar application different sodium selenate concentrations (0, 5, 10, 15, 20 mg/L) was used to treat cauliflower cultivars “Clapton” “Graffiti”. Higher yields other related vegetative attributes were improved at 10 15 mg/L application. At a concentration selenate, photosynthetic pigments, total phenolic...

This study aimed to assess the morphological and physio-biochemical responses of a commercial watermelon (Citrullus lanatus (Thunb.) Matsum. Nakai) cv. ‘Crimson Sweet’ grafted onto drought-tolerant rootstock wild (bitter apple, Citrullus colocynthis (L.) Schrad, ‘Esfahan’) in comparison with an ungrafted or one interspecific Cucurbita hybrid (Cucurbita maxima Duch. × moschata Duch.) (‘Shintoza’) under water stress. The experiment was conducted pots controlled environment greenhouse, stress...

Carotenoids and chlorophylls are among the most widely distributed pigments in nature that play essential roles photosynthetic apparatus confer diverse colours plants. Among all vegetables, cauliflower (Brassica oleracea L. ssp var. botrytis) is rich phytochemicals an important crop grown over world. This study investigates carotenoid chlorophyll concentrations differently pigmented cultivars elucidates role of transcriptional regulation accumulation including lutein β-carotene. Here, we...

Water deficiency is an environmental factor affecting crop yield especially in arid and semiarid regions. It necessary to improve water use efficiency watermelon (Citrullus lanatus Thunb), a high-water requiring crop. The edible accessions, "TN-94-766," "TN-94-769," "TN-94–545," "TN-94-485," "Crimson Sweet," the wild-type Colocynth were treated with irrigation regimes of 100%, 80%, 60%, or 40% soil available water. In all leaf area shoot length decreased root increased as availability up AW....

Selecting appropriate rootstocks in grafting is an important aspect to increase yield and fruit quality of vegetables.Interspecific hybrids gourd are the most frequently used for watermelon (Citrullus lanatus var.(Thunb.)Matsum.& Nakai) grafting.However, other Citrullus species such as bitter apple colocynthis (L.) Schrad) have not been completely exploited can be a source interesting traits.The present study aimed evaluate potential rootstock (cv.Crimson Sweet) comparison commercial...

Dudaim melon ( Cucumis melo Group Dudaim) is a unique edible for which few postharvest physiology studies have been conducted. To investigate the behavior of dudaim melon, two cultivars (Zangi-Abad and Kermanshah) were planted, tagged at anthesis, harvested maturity stages: 21 28 d after anthesis (DAA). Harvested fruit stored 5 or 13 °C up to 3 weeks various quality parameters including color, firmness, titratable acidity (TA), total soluble solids (TSS), weight loss, chilling injury (CI),...

Artemisia dracunculus L. (tarragon), known as "tarkhun" in Iran, is a perennial herb the Asteraceae family, which has long history of use culinary traditions. A factorial experiment based on Randomized Completely Block Design with three replications was used. The treatments were performed at four level foliar applications Ca(NO3)2 and KNO3 fertilizers (including control (sprayed water), 1.5, 3 6 gl-1). This conducted field conditions farm "Ray" 2010. results showed that application...

Understanding genetic diversity and germplasm classification are the keys for selection of right parents breeding purposes. In present study, 45 Iranian 15 foreign melons were evaluated. A greenhouse experiment was laid out as a randomized completely block design with three replications five plants in each replicates. Fruit number had positive correlation female flower numbers, fruit number, yield. The however, correlated negatively leaf area. Genotypes monoicous flowering habit produced...

Rind color in melon is one of the major fruit attributes at harvest and postharvest during storage period. Since commercially available chromameter results are expressed as average values few chosen points, these may be inaccurate when representing whole surface a large such melon. This research aimed to develop portable low-cost system measure parameters rind CIELAB space calculate changes after cold period using image analysis method. For this purpose, an imaging box with appropriate...

The purpose of this study was to estimate heritability, general and specific combining ability the relationship between traits. Investigated traits were fruit number per plant, total yield average weight, flesh thickness, firmness, seed cavity size, soluble solid, length in melon. A complete diallel design conducted for five parental genotypes crossed hybrids evaluated a randomized block with three replications. Analysis variance showed significant differences hybrids, therefore first...

Abstract To evaluate gene effects and heritability of fruit flower characters in melon, three experiments were performed. In the first experiment, 48 genotypes different melon groups planted to choose monoecious melon. investigate sex modification regarding traits, seven parents, including a type andromonoecious types, crossed full diallel scheme obtain all possible combinations. Evaluation amongst revealed one Cantaloupensis Flexuosus with flowers. Floral F1 hybrids obtained from cross,...

To contend with water shortages there is a need to screen snake melon germplasm such as (Cucumis melo var. flexuosus L.) identify potential drought tolerant genetic resources. Finding plants that endure shortage an issue in agriculture. Inbred lines of were exposed simulated at 100%, 80%, 60%, or 40% available (AW). Yield, fruit weight, leaf area, shoot number, and total protein highest under 100% AW. Root length, glycine betaine, antioxidant enzyme activities increased increased. line 10...

Selenium is a micronutrient element that beneficial for the growth and development of plants. It has antioxidant, anticancer, antiviral properties are essential human animal health. Low-consumption mineral elements such as selenium can be included in diet from various sources. To investigate phytochemical attributes broccoli cultivar "Heracklion", an experiment with five levels concentration (0, 5, 10, 15, 20 mg/L sodium selenate) was carried out randomized complete block design 3...

Abstract Understanding the volatile profile of melon is an ever increasingly important task for breeders enhancing their flavour component. For this purpose, F1 progeny and parental lines were analysed using headspace‐solid phase microextraction gas chromatography–mass spectrometry‐based analysis. Diallel analysis showed that most investigated compounds controlled via non‐additive genetic effects with general combining ability to specific ratios less than 0.4. High heterosis results observed...
