Read More AbstractBackground and ObjectivesHyssop (Hyssopus officinalis L.) is a perennial and belongs to the Lamiaceae family. Drought is the most critical environmental stress that adversely affects crop plant performance. The use of anti-transpiration and plant protective materials is one way that has recently been raised to improve plant resistance under stress conditions. The purpose of this experiment was to investigate the effect of anti-transpiration and plant protective materials on vegetative and physiological traits of Hyssop under drought stress and foliar application time. Materials and MethodsThis research was conducted as a split-plot factorial experiment based on a completely randomized design with three replications in 2016-2017. The experimental treatments included irrigation in three levels: 25% water available from the soil (control), 50% water available from the soil (mild stress), and 75% water available from the soil (severe stress) Were the main plots. Foliar application in four levels: water (control), kaolin (2.5%), chitosan (0.4 g/ l) and glycine amino acid (2.5 per thousand), and foliar application time: (vegetative and flowering, flowering) were the subplots. In the present study, dry leaf weight, flower dry weight, essential oil yield, shoot dry weight, economic yield, harvest index, proline, and soluble sugar were measured. ResultsThe results showed that at control stress level, the foliar application of water had the highest leaf dry weight (81.3 g/m2), shoot dry weight yield (140.5 g/m2), essential oil yield (9.40 g/m2), economic yield (81.3 g/ m²), and proline content (8.558 (µM/g FW). Moreover, during flowering and vegetative + flowering, kaolin's foliar application during vegetative+flowering had the highest dry flower weight (53 g/m2). At mild stress level, the foliar application of water during vegetative+flowering included the highest amount of soluble sugar (0.396 mg/g FW), and glycine foliar application at the flowering time had the highest harvest index (79%). Also, kaolin spraying during vegetative+flowering had the highest economic yield (73 g/m), and chitosan foliar application during vegetative+flowering had the highest shoot dry weight (111 g/m²) and essential oil yield (7.55 g/m2). DiscussionDue to the beneficial effects of antiperspirants and plant protection, they can be used as suitable solutions to increase plant production and reduce drought stress in arid and semi-arid regions.

Read More Abstract Background and ObjectivesSpearmint is a perennial plant with creeping and underground stems, which belongs to the Labiatae family. After drought, salinity is the second most common environmental agent that restricts agricultural production. Glycine betaine is the most widely used organic solution known for its quadrature ammonium compounds and the largest and most abundant compound in response to stress. The purpose of this experiment was to investigate the effect of glycine betaine on some quantitative and qualitative properties of mint under salinity stress. Materials and MethodsA factorial experiment was conducted based on randomized complete block design with three replications in 2017-18. Experimental factors included salinity stress (4 levels, control, 30, 60 and 90 mM NaCl) and glycine betaine (at 3 levels of 0, 100 and 200 mM). In the present study, some growth traits, height of plant, fresh weight and dry weight of shoot, root volume, fresh and dry weight of root, photosynthetic pigments (chlorophyll a and b and total), protein, proline and soluble sugars were measured. ResultsThe results showed that salinity stress was significant for all characteristics, so that by increasing levels of salinity all traits were reduced except chlorophyll b, total chlorophyll, proline and soluble sugars. Salinity reduced plant height (29.47%), fresh weight of shoot (49.56%), dry weight of shoot (56.87%), root volume (47.89%), fresh weight of root (52.15%), dry weight of root (43.92%), photosynthetic pigments (a) (18%) and (b) (29.41%), protein content (17.79%), proline (30.98%) and soluble sugars (3.58%). Application of glycinebetaine reduced the negative effects of salinity stress, but it caused reduced height (9.16%) and chlorophyll b (26.31%) compared to control. Also, interactions between salinity stress and foliar application of glycinebetaine were significant for shoot fresh weight, shoot dry weight, root fresh weigh, root dry weight, proline, protein (p < 0.01), root volume and soluble sugars (P<0.05). The highest values of the studied traits were obtained for the interaction between 7 mM NaCl and 200 mM glycinebetaine. DiscussionSalinity stress reduces the growth of plants through osmotic stress, ion toxicity and nutritional imbalance. However, glycine betaine, as an important osmolite in plants, increases the osmotic potential and improves the water relations and increases the activity of photosynthesis and the production of hydrocarbon materials. In this way, glycine betaine can protect against the stress of salinity by increasing the mechanisms of tolerance to salinity and will provide better conditions for plant growth in a saline environment.
