Two field experiments were used to determine the yield potential of 'Long Pod' cayenne hot peppers due to foliar application of 528 ppm each of chlormequat chloride. ethephon, and ancymidol. Applications were either made at bud formation, fruit development or fruit ripening periods. At last harvest, samples of marketable red-ripe fruits from the border rows of both 'Long Pod' cayenne and “Oriental-l” hot pepper plots were used for hot pepper sauce formulations. Two sets of 32 panelists each, were used to evaluate both the newly formulated experimental (ICES-1 and EHS-2) and commercial (CHS-1 and CHS-2) hot peppers sauces for quality. In 1990, marketable yield was highest due to chlormequat chloride. and for application made at fruit ripening. In 1991, marketable yield was highest due to ancymidol application, and for application made at fruit ripening. Mean sensory scores for hot sauce appearance, flavor and texture were generally highest for experimental hot sauces, whereas pungency scores were highest due to “CHS-1” commercial hot sauce.

This investigation was carried out in the lath house of the nursery of Malta station/ Duhok. Kurdistan region, Iraq. During the growing season of 2017, to study the effect of the different concentrations of  Fe (0, 10 and 20 mg.L -1) and GA3 (0 , 500 and 1000 mg.L-1) on vegetative growth,  roots length  and leaves nutrients content of one year old of  two olive cultivars (Nebali and Bashike) transplantings. The results appear that  Nebali cultivar significantly dominated in stem length (cm), stem diameter(mm),  branch length(cm), leaves number, root length(cm), N(%), K(%), P(%) and Fe(mg.L-1), Baeshike cultivar dominate in leaf area (cm2), stem length(cm) , shoot root ratio(%), root length(cm) and K (%) were significantly increased with the increase the GA3 to 1000 mg.L-1. Foliar application of GA3 at 500 mg.L-1 significantly increased branch length (cm) and P (%). The transplants sprayed with the Fe in 10 mg.L-1 only significantly effect on the Fe % content but spray transplants with the Fe at 20 mg.L-1 had significantly affected on stem diameter(mm), leave number root length(cm) and N(%). Most of the interactions (cultivar × Fe and cultivar × GA3) showed significant effects on the most studied characteristics.

Abstract The experiment was conducted in the Directorate of Agriculture in Najaf during the agricultural season 2020-2021 to know the effect of Foliar application of thiamine and Roselle extract on the chemical parameters of the Mathiola plant(Matthiola incana L).The experiment included two factors, the first is thiamine at four concentrations (90,60,30,0) mg.L-1. The second is Roselle extract at four concentrations (0,2,4,6) g.L-1, a factorial experiment was conducted consisting of three replicates, the experiment was conducted based on the Randomized Complete Block Design (R.C.B.D) 4×4×3=48, The results can be summarized that thiamine at a concentration of 90 mg.L-1 with Roselle extract at a concentration of 6.4 g.L-1 when sprayed on the plant led to a significant increase in the study parameters as the leaves content of total chlorophyll and nitrogen phosphorous potassium, boron and the total soluble carbohydrate content of the leaves and the anthocyanin content of the flowers were increased reached to 57.27 mg.100 g-1 and 2.45% and 0.29% and 2.96% and 13.72 mg.kg-1 and 18.10 mg.g-1 respectively.

While ethephon [(2-chloroethyl) phosphonic acid] has increased yields of red fruits, its use as a pepper (Capsicum annuum L.) fruit ripening agent has been limited by premature fruit abscission and defoliation. We tested ethephon solutions of 0, 1500, 3000, 4500, and 6000 μl·liter-1 with or without 0.1M Ca(OH)2 as a one-time foliar application to field-grown paprika pepper in southwestern Oklahoma. There was a linear increase in fruit abscission with increasing ethephon rates in two out of three years, with or without added calcium. Ethephon at 6000 μl·liter-1 improved the percent of total fruit weight due lo marketable fruits in two out of three years, primarily by decreasing the weight of harvested green fruits. However, ethephon never significantly increased the dry weight of harvested marketable fruits over that obtained from the control. There also was no effect of ethephon on the intensity of red pigment extracted from dehydrated marketable fruits. The only significant effect of Ca(OH)2 was an undesirable increase in the retention of green fruits on the plants. Ethephon had little value as a fruit ripening agent for paprika under the conditions of our studies, and Ca(OH)2 was not useful as an additive to ethephon sprays.

Submergence Stress

Recovery from submergence stress is vital for plant regrowth. The objective of this study was to characterize plant growth, carbohydrate, and antioxidant metabolism of creeping bentgrass (Agrostis stolonifera) to foliar application of nitrogen and cytokinin (CK) after de-submergence. Creeping bentgrass (cv. Penncross and 007) were submerged under the water for 14 days and then foliar-sprayed at 1, 2, 3, 7, and 14 days after de-submergence with six types of chemical treatments, respectively: 1) water (W); 2) 10 mm urea (N10); 3) 20 mm urea (N20); 4) 10 µm CK; 5) N10 with CK (N10CK); and 6) N20 with CK (N20CK). Leaves were harvested at 20 days after chemical applications for various measurements. Compared with the nonstressed plants, plant height (HT), chlorophyll index (Chl), leaf dry weight (DW), water-soluble carbohydrate content (WSC), activities of superoxide dismutase (SOD), and ascorbate peroxidase (APX) decreased, but catalase (CAT) and peroxidase (POD) activities, malondialdehyde (MDA), and total soluble protein (TSP) content increased in both cultivars exposed to 14 days of submergence. After de-submergence, plants treated with N alone (N10, N20) or combined with CK (N10CK, N20CK) generally had higher HT, DW, Chl, TSP, and a lower amount of MDA, compared with treatments of W or CK alone, whereas treatment using CK resulted in higher WSC for both cultivars. Foliar applications of N and CK had some effect on SOD, CAT, POD, and APX activities after de-submergence, but the effects were not consistent across chemicals and cultivars. The results indicated that foliar application of N or combined with CK promoted plant growth and reduced lipid peroxidation after de-submergence. The results also suggested a more positive role of foliar N application in comparison with a complex regulation of CK on creeping bentgrass regrowth after de-submergence.
