ABSTRACT The objective of this study was to evaluate the effect of a plant growth regulator (PGR; Stimulate®) on the yield and quality of zucchini fruits from plants of the cultivar Caserta-Italiana grown under different salinity levels of the irrigation water (SLIW). A randomized block design was used, in a 2 × 6 factorial arrangement consisted of two SLIW (0.5 and 5.0 dS m-1) and six PGR application modes: imbibition of seeds for 8 h in distilled water (PGR-T1; Control); imbibition of seeds for 8 h in PGR at 10 mL L-1 (PGR-T2); imbibition of seeds for 8 h in PGR at 10 mL L-1 plus foliar application at 10 mL L-1 at the flowering stage (PGR-T3); imbibition of seeds for 8 h in PGR at 10 mL L-1 plus two foliar applications at the flowering stage and at 20 and 30 days after sowing (PGR-T4); foliar application at 10 mL L-1 at the flowering stage (PGR-T5); and two foliar applications at 10 mL L-1 at 20 and 30 days after sowing (PGR-T6). The SLIW affected differently the variables of the zucchini crops evaluated. The PGR application to plants under no salt stress (0.5 dS m-1) increased the solid soluble concentration and biomass accumulation of zucchini fruits. The PGR application as seed treatment and foliar application at the flowering stage increased the fruit yield of zucchini plants irrigated with saline water.

The water in semiarid regions contains salts in excess. When good quality water is not available it is necessary to use strategies that can make feasible the use of saline water. The aim of this study was to evaluate the effects of the application of the plant growth regulator on the culture of basil stressed with salt. The experiment was carried out in a randomized block design by the matrix “Central Box Compound”. Shoot height, stem diameter, leaf area, dry masses and soil chemical characteristics were evaluated. The salinity of the irrigation water causes reduction of the basil growth parameters, with the exception of the inflorescence dry mass. Plant growth regulator applications have effect on basil growth when plants are irrigated with saline water.

A model system was devised to study the translocation of 2,4-D in leafy spurge (Euphorbia esula L.). The effects of rate of 2,4-D application, decapitation, and rate and pretreatment with ethephon on 14C-2,4-D translocation were studied. Rooted cuttings were obtained by rooting newly-developed axillary shoots in moist vermiculite for 4 wk. These cuttings were then placed in liquid nutrient medium for translocation experiments. Seven days after application, 50–60% of the 14C translocated from 14C-2,4-D treated leaves was found in the stem. The percentage of 14C that accumulated in the stem increased with increasing rate of 2,4-D application to 1 kg/ha. Up to 85% of 14C translocated to the root was released into the nutrient medium. Shoot decapitation 5 mm below the apex up to 4 days before 2,4-D application decreased 14C percentage in leaf tissue and increased 14C in stem and root. Foliar application of ethephon at 1 kg/ha resulted in a transient increase in the rate of ethylene evolution from shoot and root tissues, decreased the amount of 14C translocated to the root zone and increased the 14C in the leaves. Ethephon treatment of larger, vermiculite-grown plants also decreased 14C accumulation in the roots. These results indicate that the use of root cuttings is a convenient and reliable method for the study of herbicide translocation and plant growth regulator/herbicide interactions in leafy spurge.Key words: Translocation, 2,4-D, leafy spurge, Euphorbia esula L., plant growth regulator, ethephon

Laxogenoside-C (LG-C) has BRs-likely activity and with higher activity stability. In this study, the LG-C and SsS (the mixture of Laxogenoside-A, -B, and -C; isolated from the Smilax scobinicaulis C.H. Wright) were used to conduct the seeding treatment and greenhouse experiments with different application time and concentrations, to clarify the effect on yield and quality of radish (Raphanus sativus L.) for development of a new plant growth regulator. The results showed that 10 μM LG-C and SsS increased hypocotyls, elongation and cotyledon weight compared with other treatment. The greenhouse experiments indicated that the interaction effect of plant growth regulator types and application time was significant for all parameters except for phosphorus content. An application of LG-C or SsS produced a higher yield than multiple times. Compared with T0 treatment, LG-C and SsS sprayed at root enlargement (T4) increased yield by 25.33% and 24.10%, respectively. T4 treatment of LG-C produced the highest yield and free amino acid and phosphorus, but the other parameters not. T4 treatment of SsS not only had the highest yield and water-soluble carbohydrates and water-soluble protein but also improved the other radish quality. In conclusion, this study indicated that the application of SsS at root enlargement with 10 μM improved radish root tubers yield and quality.

Aim: To assess the pleiotropic role of a plant growth regulator, commercially identified as brassinolide (BR) in mitigating waterlogging stress imposed on maize. Study Design: A factorial combination of two maize varieties [Ikom White (IKW) and Oba-98], two BR levels (0 and 250 ml) and two waterlogging stages of maize growth [control (WL0) and seedling stage (WL1)], arranged as a split-split plot in a randomized complete block design with three replications was used. Place and Duration of Study: Akpabuyo Local Government Area, Cross River State-Nigeria. A two-year field experiment was conducted during the dry seasons of December 2016 and December 2017. Methodology: Waterlogging test was conducted on plots by demarcating them with 3.6 by 1.7 m metal sheets buried to a depth of 60 cm to prevent lateral soil-water movement. Two maize seeds were sown at 25 cm within and 75 cm between rows. The BR (250 ml) was sprayed foliar at 21 DAS. The non-waterlogging plots served as control. Observations were made on growth and yield variables as well as the plant's physiological traits. Results: Waterlogging significantly reduced the growth attributes of maize and increased (p≤0.05) the leaf moisture content. The photosynthetically active radiation on maize plants was substantially reduced (p≤0.05) by the waterlogging stress. Dry matter yield (DMY) and nutrient uptake in the leaves, stems and grains were reduced (p≤0.05) at both silking and at harvest. The effect of the BR was greater in Oba-98 with higher nutrient contents, radiation absorption, dry matter and grain yields than IKW. Conclusion: Treatment of maize plants with BR could induce some tolerance of field waterlogging. Thus, for optimum efficiency in maize production under stressed soil condition of waterlogging, it is recommended that the foliar spray of BR at the 250 ml per plant rate be considered.

ABSTRACT: Abiotic stresses and poor biomass accumulation are chief constraints to accomplish potential yield in Leymus chinensis. An experiment was conducted to improve biomass and correlation of biomass accumulating attributes with photosynthetic pigments, osmotic substances and antioxidants under foliar application of different plant growth substances. The experiment was conducted at inner Mongolia Xilinguole, China, using a Randomized Complete Block Design and 5 replications. The treatments consisted of water (control); BA5 = application of BA (6-benzylaminopurine) at 5 mg L-1; BA25 = application of BA at 25 mg L-1; BA50 = application of BA at 50 mg L-1; BR0.02 = application of BR (brassinosteroid) at 0.02 g L-1; BR0.2 = application of BR at 0.2 mg L 1; BR2 = application of BR at 2 mg L-1; GA10 = application of GA (gibberellic acid) at 10 mg L-1; GA50 = application of GA at 50 mg L-1 and GA100 = application of GA at 100 mg L-1. Application of all plant growth substances significantly improved biomass, osmotic adjustments, photosynthetic pigments and antioxidant activities compared to control. However, the most promising results were found with 0.2 mg L-1 BR. The highest chlorophyll a/b, glutathione and ascorbate peroxidase activities were recorded with 25 mg L-1 BA. Conclusively, 25 mg L-1 BA, 0.2 mg L-1 BR and 10 mg L-1 GA exhibited more promising results than other concentrations for the evaluated attributes.

Introduction: This study aims to obtain concentration of shallot extract (Allium cepa ) and growth regulators to increase growth of Mucuna bracteata. Mucuna is a land cover plant that must be planted in oil palm plantation areas. It is very important to be able to cover the planting area. Materials and Methods: This study used two factorial in randomized block design. The first was concentration of shallot extract per 100 ml distilled water consists of 4 levels, such as control (B0), 10 cc (B1), 20 cc (B2), 30 cc (B3) and the second was the auxins-plant growth regulator consists of 4 levels: Control (G0), 100 ppm (G1), 200 ppm (G2), 300 ppm (G3). Data analyzed with ANOVA with a significant 5% and continued with the DMRT using SAS version 9.1.3. Results: It was found that effect of concentration of shallot extract had a significant effect on survival percentage of Mucuna bracteata at a concentration of 10 cc (B2) after opening the lid at four weeks after planting (WAP) and did not change until 8 WAP. Likewise, the number of leaves at the control concentration (B0) at the age of 6 WAP, and a concentration of 10 cc (B1) at the age of 7-8 WAP. The concentration of growth regulators and their interactions did not significantly affect the survive percentage and number of leaves in Mucuna bracteata.
