“…The rate of photosynthesis and the efficiency of light energy utilization play a critical role in plant growth (Semesi et al, 2009;Liao et al, 2022). Currently, research on both terrestrial (Hussain et al, 2020) and aquatic plants (Balestri and Bertini, 2003;Balestri and Lardicci, 2006) supports the conclusion that IAA and GA 3 application improves plant photomorphogenesis and promotes efficient photosynthesis by leaves. We found that the application of IAA and GA 3 enhanced rETR max , F m , F v /F m , q P , F PSII , and photosynthetic pigment content in the leaves of TTFs, and reduced their F o and NPQ (Figures 4 and 5; Table 1).…”

IntroductionThe transplantation of seagrass fragments with shoots and rhizomes is the most common method for the ecological restoration of damaged seagrass meadows.MethodsThe aim of this study was to explore the effects of exogenous addition (10 mg per month for 3 months) of three commonly used plant growth regulators (PGRs), including indoleacetic acid (IAA), gibberellin (GA3), and paclobutrazol (PP333) on the growth and physiology of transplanted Thalassia hemprichii fragments (TTFs), with and without the rhizome apex (RA), using a simulation test. [Results] IAA and GA3 elevated the photosynthetic capacity and growth rate of TTF leaves but did not significantly alter leaf length and width. In contrast, PP333 reduced the leaf photosynthetic capacity and growth rate, while greatly increasing the leaf width and root viability. Additionally, PP333 treatment led to an increase in antioxidant enzyme activities (peroxidase [POD], superoxide dismutase [SOD], and catalase [CAT]), as well as malondialdehyde (MDA) and total phenol contents in TTFs, indicating some stress effects on the seagrass. Furthermore, IAA and GA3 decreased soluble sugar and protein contents and increased starch content in TTF tissues, whereas PP333 treatment elevated both nonstructural carbohydrate and soluble protein contents. The presence of RA positively affected the growth and physiology of T. hemprichii compared with TTFs without RA. There was a significant interaction between the PGRs and RA on leaf growth rate, chlorophyll fluorescence variables, and photosynthetic pigment content of the TTFs (p < 0.05).DiscussionThis study provides guidelines for the application of PGRs during the transplantation of T. hemprichii fragments for the restoration of seagrass meadows.

“…It was shown that the use of IAA considerably improved the morphological, physiological, yield, and biochemical characteristics (Hussain et al, 2020). The fact that auxin and gibberellins (GA) created a considerable stimulation for plant development may be the cause of the rise in morphological characteristics.…”

In order to investigate the potential of Indole Acetic Acid (IAA) for affecting yield contributing factors and Nitrate Reductase Activity, an experiment was conducted on four Vigna mungo genotypes. The four mash bean genotypes, 80, 88, 97, and ES-1, were examined against Indole Acetic Acid concentrations of 25, 50, 75, 10, 12, and 150.0 mgL-1. Plants were grown in pots which were randomly placed in the Botanical garden of Bahauddin Zakariya University, Multan. Pakistan. Four replicates of each treatment were developed and evaluated. Aforementioned amounts of Indole Acetic Acid were sprayed thrice, with intervals of ten days each. Ist spray was conducted at twenty days after germination. Nitrate Reductase Activity, grains number fruit-1, legumes number plant-1, and plant total yield were the traits chosen for study. After ten days of completion of three sprays of Indole Acetic Acid, Nitrate Reductase Activity (NRA) in the leaves was evaluated, and yield plant-1and its contributing factors were noted when the crop reached at its physiological maturity. Typically, an exponential increase in the number of grains, legume per plant, total yield, and Nitrate Reductase Activity (NRA) was seen as Indole Acetic Acid concentration increased from 75.0 to125.0mgL-1. By using a statistical technique, it was found that the responses of different genotypes to Indole Acetic Acid concentrations varied. MASH 97 was proved to be the most influenced in term of total yield plant-1, the number of grains plants-1 and the Nitrate Reductase Activity (NRA). While, MASH ES-1 performance lagged behind all other genotypes. Keywords: Indole Acetic Acid; Legumes; Nitrate Reductase; Vigna; Yield; Pods

“…In crop growth and development, auxins as Indole acetic acid (IAA) plays an extremely effective role (Dimkpa et al, 2009). According to Hussain et al (2011), foliar spray of IAA is very useful for the enhancement of yield and plant growth. It was noted that auxins increased the number of pods and seeds and the yield of seeds in Pea (El-Shraiy and Hegazi, 2009).…”

Background: Pea is the most important crop and vegetable in the world but it has low yield. There is a need to find the ways for the improvement of crop productivity. Plant growth regulators (PGRs) are extensively used in many crops for enhancement of yield and quality. This study was designed to find the influence of PGRs on growth, yield and quality of pea cultivars grown in Pakistan. Methods: Pot experiments were conducted to evaluate the effect of various plant growth regulators (IAA, NAA and GA3) on pea during 2018-19. Four cultivars of pea i.e. Meteor, Green cross, Sultan and Dollar were used in these experiments. There were 0, 100 and 200 mmol’×L-1 levels for each hormone that were applied as foliar spray after 14 days of germination. Experiment was laid down in completely randomized design (CRD) with three replicates. Results: Morphological, biochemical and yield attributes significantly increased in four cultivars of pea except variety Sultan for few parameters. Cultivar Meteor showed highly positive increasing effects on growth and yield attributes as compared to other treatments. Catalases (CAT) activities were increased and peroxidase dismutase (POD) activities were reduced. It can be concluded that reduction in POD activities helped to increase the defense mechanism of plants and high CAT activities caused better balance in plant metabolism as a result growth, yield and quality of pea were increased. All the variables including shoot length, shoot biomass, number of fruits, total seed yield, carbohydrates and protein had positive correlation with phytohormones. These outcomes might be good indicators to predict the best pea cultivars that can have positive promising response for growth, yield and quality traits under plant growth regulators (PGR).
