Thyme, mint, and lemon balm were used to determine whether shading conditions could improve the yield, composition, antioxidant, antimicrobial activity in plant essential oils (EOs) comparison with non-shaded plants from an open field. The yield of EOs thyme, balm, was 3.44, 3.96, 0.21 mL/100 g, respectively. Plants covered by nets produced different levels (3.46, 2.20, 0.45 g) after 120 min hydrodistillation. main components thyme oil are thymol (44.2–43.9%), γ-terpinene (18.3–16.8%),...

The study was conducted to determine fennel essential oil (FEO) yield, composition, and antioxidant activity during four different maturation stages of umbels with seeds (1st stage: immature-pasty; 2nd premature-waxy; 3rd mature-fully ripe; 4th only), leaves wild (Foeniculum vulgare Mill. subsp. vulgare) from the Montenegro coast. maximum yield found in premature at waxy stage (4.76 mL/100 g p.m.) fully ripe early fruiting (5.16 p.m.). Fully contained lowest FEO (mL/100 minimum content...

Abstract BACKGROUND The need to increase marketable tomato yields and decrease losses due sunburn disease during the summer motivates farmers adopt additional cultural practices such as shading grafting. To investigate complex interactions among grafting, shading, cultivar, grafted ungrafted tomatoes (cv. 'Optima' F 1 cv. 'Big Beef' ) were grown in soil under net‐house cover, using pearl red nets, unshaded conditions (open fields). Tomato fruit at stage of maturity used for analysis quality...

The aim of this study was to determine the antimicrobial activity essential oils obtained from sweet basil (Ocimum basilicum L. cv. ‘Genovese’) cultivated in open field under different shading conditions (red, blue, and pearl nets with a shade index 50% full sunlight exposure (control plants)), harvested at times. (BEOs) all samples determined for four microorganisms, while determinations an additional five microorganisms included non-shaded plants, plants grown red nets, second harvest blue...
