“…So far, nine categories of phytohormones have been identified. These include auxins, cytokinins (CK), gibberellins (GA), abscisic acid, (ABA), ethylene (ET), brassinosteroids (BR), salicylates (SA), jasmonates (JA), and strigolactones (SL) (Su et al, 2017). These hormones are not only produced by plants but are also produced by beneficial and pathogenic microorganism (e.g.…”

Role of Cytokinins for Interactions of Plants With Microbial Pathogens and Pest Insects

It has been recognized that cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other organisms, including pathogens. Cytokinins are not only produced by plants but are also by other prokaryotic and eukaryotic organism such as bacteria, fungi, microalgae and insects. Notably, cytokinins are produced both by pathogenic and also beneficial microbes and are known to induce resistance in plants against pathogen infections. In this review the contrasting role of cytokinin for the defence and susceptibility of plants against bacterial and fungal pathogen and pest insects is assessed. We also discuss the cross talk of cytokinins with other phytohormones and the underlying mechanism involved in enhancing plant immunity against pathogen infections and explore possible practical applications in crop plant production.

“…The main objective of this article was to summarize the recent advances in the use of various plant growth regulators in increasing production efficacy of ber (Ziziphus maurtiana) fruit. Plant growth regulators: Plant growth regulators are the non-naturally occurring synthetic compounds (Su et al, 2017) requires in minute quantity to promote or inhibit the plant physiological process (Rademacher 2015). PGRs regulate the growth and development of plants by regulating the internal processes (Bons et al, 2015).…”

“…abscisic acid, cytokinins, gibberellins and ethylene were also identified as synthetic plant hormones (Kende and Zeevaart, 1997;Ferguson and Lessenger 2006). Since then marked experiments has done to identify their efficacy in the regulation of plant physiological process (Sara et al 2014;Su, 2017). Discovery of plant hormones and identification of their efficacy in the improvement of yield and qualitative parameters had a great impact on the fruit production (Bisht et al, 2018).…”

Ber (Ziziphus maurtiana) is an important minor fruit crop of India. Over the years the crop is now widely domesticated and commercial orchards of Ber are now available. With wide commercialization, many physiological problems, i.e. flowers and fruit drop, embryo abortion, poor flowering and fruit setting, abnormal and small size fruits etc. were observed which cause huge loss to the growers. In order to minimize these problems, over the years many experiments and advancement have been done, and among them, usage of plant growth regulators is one of the most adopted methods and is utilized to improve flowering fruiting and yield with improved fruit quality. The current review discusses the role of different plant growth regulators and how they influence each fruit character. This information could be useful to the researchers in planning further advance research in this aspect and for the commercial growers to decide the proper treatments to mitigate the problems.

“…A decline in the antioxidant enzymatic activities by yeast extract spray was recorded in the drought stressed wheat which is concomitant with the results of El-Ghinbihi & Hassan (2007). Many of the effects of yeast extract, as a bio stimulant, are based on their ability to influence the hormonal activity of plants (Su et al, 2017) which can alter the plant's hormonal status and have a major influence on its growth and health, and act as a hormonal and nutritional increment factor (Vasconcelos & Chaves, 2019).…”

Yeast Extract and Lithovit Mineral Fertilizer Ameliorate the Harmful Effects of Drought Stress in Wheat

2020

T HE effects of two levels of drought stress (25% and 50% of FC) and the control (75% FC) on the growth, some physiological processes and some metabolites in wheat (Triticum aestivum, cv. Masr 2) at seedling (30 days), vegetative (65 days) and yield (160 days) stages were studied. The ameliorative effects of the foliar spray for the harmful effects of drought by the bio-stimulant yeast extract (10%) or the mineral fertilizer lithovit (3.8%) were also studied. The results showed that both levels of drought stress decreased all of the measured growth criteria and chl a and chl b at both growth stages. The foliar spray with yeast extract or lithovit resulted in the alleviation of these inhibitory effects. Carotenoids increased with drought stress but decreased using both foliar spray treatments. Carbohydrates and total soluble proteins decreased under both drought levels, but using yeast extract or lithovit treatment alleviated these effects. Higher activities of catalase, peroxidase and ascorbic oxidase were recorded under the two stress levels, while yeast extract and lithovit treatments inhibited them. At yield stage, both drought levels resulted in severe reduction in all yield parameters, carbohydrates and total soluble proteins contents in the produced grains. Foliar spray with yeast extract or lithovit improved all the measured parameters of yield and increased the contents of the metabolites in the grains. Although lithovit was slightly more effective than yeast extract, the latter treatment seems preferable as it is a natural product with no apparent residual effects on plants and soil.
