“…IAA bosses many different effects, such as inducing cell elongation and cell division with all subsequent results for plant growth and development (Teale et al, 2006). On a larger scale, IAA serves as a signaling molecule necessary for the coordination of growth and development of plant organs (Aldesuquy, 2000). BA is a synthetic cytokinin that stimulates cell division in plants.…”

“…A homogenous lot of pea seeds Intisar 2 (obtained from the Agricultural Research center, Giza, Egypt) were surface sterilized by soaking in 0.01M HgCl2 solution for one min, washed thoroughly with distilled water then, divided into four sets. Seeds of the 1 st set were pre-soaked in distilled water to serve as a control, while seeds of the 2 nd set were soaked in 10 -9 µg/ml IAA, 3 rd set was soaked 10 -6 µg/ml BA, while the 4 th set was soaked in a combination of the previous concentrations of IAA+BA; all seeds were left in the soaking solution for 3h (Aldesuquy, 2000). All treated seeds were planted in plastic pots (40 cm diameter and 45 cm depth); each pot was filled with about 3.5kg of sterilized peat moss soil containing 5 seeds.…”

“…Cytokinins affect seed germination, root and shoot differentiation, leaf senescence and plant-microbe interactions particularly the formation of nodules not only auxins (Santner and Estelle, 2009). Seed priming with indole-3-acetic acid (IAA) at 25 mg kg -1 stimulated the flag leaf growth, namely its fresh an dry masses, leaf area, pigment, saccharides and protein formation as well as its effect on 14 co 2 fixation in wheat flag leaf (Aldesuquy, 2000).…”

Pea (Pisum sativum intisar2) is one of the most important leguminous vegetable crops worldwide. This study was carried out to evaluate the effect of indole-3-acetic acid (IAA), benzyl adenine (BA) or their interaction on the growth vigor of both root and shoot, leaf area, pigment content as well as yield attributes and metabolism of pea plants. In the majority of cases, primily pea seeds in 10-9 µg/ml IAA, 10-6 µg/ml BA or their combination caused marked increase (p ≤ 0.05) in root, shoot growth vigor, pigment content, total soluble sugars, total protein of pea leaves as well as yield attributes (i.e pods number/plant, no of seeds/ pod and 100 seed weight). The magnitude of increase of pea plants was more pronounced in the following order: IAA > (IAA+BA)> BA. In conclusion, the results cleared that IAA is the best treatment for improving the growth and productivity of pea plants.

“…Similar studies showed that IAA inhibited the expression of senescence associated gene and reduced accumulation of 1-amino cyclopropane carboxylic acid, thereby reduced the biosynthesis of ethylene (Bao et al 2001). IAA could improve pigment production and delayed leaf senescence (Aldesuquy 2000). Although it has been reported that ABA accelerated leaf senescence (Hung and Kao 2004), molecular genetic analysis indicated that there was not a crucial link between ABA and senescence (Fedoroff 2002;Jing et al 2003).…”

Application of abscisic acid regulates antioxidant enzymes activities and modulates endosperm cell division in winter wheat

et al. 2016

Effects of exogenous abscisic acid (ABA) on antioxidant enzymes activities and endosperm cell division of two wheat (Triticum aestivum L.) cultivars were investigated. Results showed that the superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activity in flag leaves of both cultivars is elevated by application of ABA and it is correlated with less membrane damage: lower malondialdehyde (MDA). Exogenous ABA significantly increased endosperm cell number and endosperm division rate, finally increased grain weight. Although ABA treatment decreased endogenous zeatin riboside (ZR) content in flag leaves from 7 to 28 days after anthesis (DAA), indole acetic acid (IAA) levels were significantly increased by spraying with ABA. Correlation analysis showed that endogenous contents of ZR, ABA, and IAA in grains were positively and significantly correlated with grain-filling rate. IAA content in leaves was positively and significantly correlated with grain-filling rate. The results suggested that increased grain weight of ABA-treated plants was due to higher antioxidant abilities of flag leaf resulting in longer maintenance of photosynthetic capacity and higher grain-filling rate.Key words: hormones, antioxidant enzymes, malondialdehyde, grain filling, staygreen, Triticum aestivum L.Résumé : Les auteurs ont examiné les effets de l'acide abscissique (AA) exogène sur l'activité des enzymes antioxydants et la division des cellules dans l'endosperme de deux cultivars de blé (Triticum aestivum L.). Les résultats indiquent que l'application d'AA augmente l'activité de la superoxyde dismutase (SOD), de la peroxydase (POD) et de la catalase (CAT) dans les feuilles paniculaires des deux variétés, et que cette hausse est corrélée à des dommages moins importants à la membrane cellulaire, à savoir une concentration plus faible de malondialdéhyde (MDA). L'AA exogène accroît le nombre et la multiplication des cellules dans l'endosperme de façon significative, ce qui a pour conséquence de donner un grain plus lourd. Bien que l'application d'AA diminue la concentration de zéatine riboside (ZR) endogène dans les feuilles paniculaires sept à 28 jours après l'anthèse, la pulvérisation d'AA augmente significativement la celle d'acide indole acétique (IAA). L'analyse des corrélations révèle que la teneur endogène en ZR, AA, et IAA du grain est positivement et significativement corrélée au remplissage du grain. La concentration d'IAA dans les feuilles présente une corrélation positive significative avec ce facteur. Les résultats donnent à penser que le poids plus élevé du grain des plants traités à l'AA est attribuable au meilleur pouvoir antioxydant de la feuille paniculaire, qui permet à la photosynthèse de se poursuivre plus longtemps et au grain de se remplir davantage.

The effect of seed presoaking with different concentrations of growth bio-regulators (indole acetic acid, gibberellic acid and kinetin) on productivity and some biochemical and physiological aspects of yielded seeds of cowpea (Vigna sinensis L.) was investigated. Generally, application of growth regulators stimulated yield and yield quality of cowpea plants as compared to control plants through inducing a massive increase in number of pods/plants, seed biomass, pod length and number of seeds. In addition, results of this study showed that these growth regulators increased protein content and total soluble sugars in cowpea yielded seeds. Finally, it is evident from the present data that application of kinetin appeared to be the most effective hormone in stimulated productivity endogenous hormones and biochemical aspects in yielded seeds of cowpea plants.
