“…Some regulators have recently been introduced to control maize lodging (Schluttenhofer et al, 2011). Plant growth regulators can optimize plant morphology and increase yield by regulating endogenous plant hormone signaling and metabolism (Naeem et al, 2012;Zeng et al, 2012). Different plant growth regulators have been applied to maize, such as ethephon (Shekoofa and Emam, 2008), mepiquat chloride (Kamran et al, 2018c), paclobutrazol (Kamran et al, 2020), and uniconazole (Schluttenhofer et al, 2011), in the context of lodging resistance and maize yield improvement; however, the effect on vegetative (and perhaps generative) plant growth is highly dependent on the time of application and dosage of plant growth regulator and probably varies with the maize cultivar used (Hütsch and Schubert, 2018).…”

Combating Dual Challenges in Maize Under High Planting Density: Stem Lodging and Kernel Abortion

et al. 2021

High plant density is considered a proficient approach to increase maize production in countries with limited agricultural land; however, this creates a high risk of stem lodging and kernel abortion by reducing the ratio of biomass to the development of the stem and ear. Stem lodging and kernel abortion are major constraints in maize yield production for high plant density cropping; therefore, it is very important to overcome stem lodging and kernel abortion in maize. In this review, we discuss various morphophysiological and genetic characteristics of maize that may reduce the risk of stem lodging and kernel abortion, with a focus on carbohydrate metabolism and partitioning in maize. These characteristics illustrate a strong relationship between stem lodging resistance and kernel abortion. Previous studies have focused on targeting lignin and cellulose accumulation to improve lodging resistance. Nonetheless, a critical analysis of the literature showed that considering sugar metabolism and examining its effects on lodging resistance and kernel abortion in maize may provide considerable results to improve maize productivity. A constructive summary of management approaches that could be used to efficiently control the effects of stem lodging and kernel abortion is also included. The preferred management choice is based on the genotype of maize; nevertheless, various genetic and physiological approaches can control stem lodging and kernel abortion. However, plant growth regulators and nutrient application can also help reduce the risk for stem lodging and kernel abortion in maize.

“…The optimal treatment for maximum yield and quality of tobacco: Plant growth regulators could involve in the improvement of plant growth and yield (Hadi et al, 2010). They can optimize the plant morphology and biomass, and improve crop quality by regulating a variety of metabolic activities (Tassi et al, 2008;Zeng et al, 2012). For instance, Ren et al, (2016) reported increased accumulation of photosynthetic products, increased grain filling rate, and improved ear character, thereby leading to increased grain yield of summer maize by spraying exogenous ethephon and diethyl aminoethyl hexanoate (DA-6).…”

Experiments, both pot and field trial, were conducted to examine the effects of exogenously applied IAA and GA3 (at 0, 10, 20 and 30 days after topping) individually or in combination, on growth and C and N metabolisms of tobacco (Nicotiana tabacum L.). Application of IAA or GA3, at low concentrations had a promising effect in terms of promoting the yield and quality of tobacco. The key enzymes' activities were also enhanced by low PGRs concentrations, which is known to be involved in the C and N metabolisms. The combined treatment of the two PGRs was more effective than the PGRs applied individually in improving the activities of nitrate reductase (NR), invertase (INV) and amylase (AMY) finally resulting in improved soluble sugars, reducing sugars, starch, total C and N, soluble proteins and nicotine content. The optimum levels for improvement of C and N metabolites were found to be GA3 at 50 mg/L and IAA at 30 mg/L.

“…Application of PGRs control plant development by regulating the endogenous hormone biosynthesis and catabolic system to facilitate the desired growth ( Zeng et al, 2012 ). PGRs have numerous advantages over traditional methods of crop production due to their effectiveness at low concentrations, wide range of applications, low toxicity, ability to regulate plant morphology and physiology, and their influence on many crop species ( Saini et al, 2013a ).…”

“…Plant growth regulators (PGRs) could be effective in realizing the yield potentials of these crops due to their numerous effects on plant life including flowering, growth, ion transport, and fruiting ( Ali & Bano, 2008 ). Again, PGRs regulate the expression of endogenous hormones, improve plant physiology metabolism, and increase crop yield ( Zeng et al, 2012 ). In particular, PGRs can optimize the process of photosynthesis and play a substantial role in maximizing crop yields.…”

Soybean [Glycine max (L.) Merrill] is a predominant edible plant and a major supply of plant protein worldwide. Global demand for soybean keeps increasing as its seeds provide essential proteins, oil, and nutraceuticals. In a quest to meet heightened demands for soybean, it has become essential to introduce agro-technical methods that promote adaptability to complex environments, improve soybean resistance to abiotic stress , and increase productivity. Plant growth regulators are mainly exploited to achieve this due to their crucial roles in plant growth and development. Increasing research suggests the influence of plant growth regulators on soybean growth and development, yield, quality, and abiotic stress responses. In an attempt to expatiate on the topic, current knowledge, and possible applications of plant growth regulators that improve growth and yield have been reviewed and discussed. Notably, the application of plant growth regulators in their appropriate concentrations at suitable growth periods relieves abiotic stress thereby increasing the yield and yield components of soybean. Moreover, the regulation effects of different growth regulators on the morphology, physiology, and yield quality of soybean are discoursed in detail.
