“…According to Reig et al (2014), NAA inhibits pollen grain germination and/or interrupts pollen tube growth, determining the development of new embryos depending on the treatment date. Although there are several studies confirming such responses in other cultures, including apple (Li, Li, & Shu, 1998), citrus (Chouza et al, 2011) and medlar (Reig et al, 2014), thus far, no studies have been performed on the effect of NAA on pollen germination and pollen tube growth, whether in vitro or in vivo for Annona species, and such studies are needed to identify the NAA mechanisms in flowers. This response associated with NAA is more evident when we observe studies of Annonaceae using only GA 3 .…”

The aim of the study was to assess the effect of plant regulators (gibberellic acid and naphthalene acetic acid) and adjuvant LI 700® with and without hand pollination on the fruiting and quality of Annona squamosa L. cultivars. The experiment was conducted in the experimental orchard of the Florida Tropical Research and Education Center (TREC/UF) in Homestead, Florida, USA. The experimental design in random blocks comprised 14 treatments, 10 repetitions and 3 flowers per treatment and per tree for ‘Red’ and ‘Lessard Thai’ cultivars. To assess quality, 9 fruit from each treatment were used, with 3 repetitions and 3 fruit per repetition. High instability was observed in fruit fixation rates between cultivars. The application of growth regulators did not increase fruit fixation in the tested cultivars. The application of naphthalene acetic acid had a deleterious effect on the flowers of the sugar apple cultivars. The most uneven (asymmetrical) fruit was obtained in the treatments with the application of growth regulators. The application of the adjuvant showed toxicity, causing damage to the skin of the fruit. The fruit with the greatest symmetry had the lowest levels of soluble solids and the highest toxicity. The application of growth regulators associated with hand pollination was not efficient, presenting a low percentage of fruit fixation for Annonaceae cultivars. None of the studied treatments produced parthenocarpic fruit (without seeds). The utilization of an adjuvant in the applied concentration caused damage to the fruit peels (darkening) due to toxicity in both cultivars.

“…Plant growth regulators can improve the physiological characteristics of crops by improving the hormone balance and other ways so as to enhance the tolerance of crops to abiotic stress and increase crop yield [33]. Li et al [35] showed that promalin (1.8% 6-BA and 1.8% GA3) diluted 6000 times could improve the texture, quality and berry weight of grapes (Vitis vinifera) effectively. Baron et al [36] found that the use of plant growth regulators alone or in combination with mineral elements was beneficial to the activity of antioxidant enzymes in grapevines, the change of photosynthetic pigment content in leaves and the transport and accumulation of reserves.…”

Drought is one of the most important factors that limit crop yield. In this study, the growth promotive activity of terrein, a microbial metabolite, on four selected agricultural plants (Vigna radiata, Brassica chinensis, Triticum aestivum and Sorghum bicolor) under drought conditions was assessed via pot experiment. Terrein effectively stimulated the seedling growth of tested species and increased their fresh and dry weight at low concentrations (2 and 10 μg/mL), either applied as a seed soaking agent or a spray solution, especially on root growth. The maximum stimulatory effect on root growth was observed on B. chinensis seedlings (99.20%), on fresh weight was found on T. aestivum seedlings (97.23%), and on dry weight was discovered on V. radiata seedlings (58.33%), implying that this stimulatory effect was species-specific. Further study revealed that the application of terrein significantly raised the contents of GA3, IAA and CTK; meanwhile, MDA content declined significantly, whereas the activity of POD, CAT and SOD was boosted significantly, suggesting that terrein can stimulate plant growth by reducing the production of ROS. Our work is the first study focusing on terrein’s plant growth promotive activity, indicating terrein has the potential to be further explored as an environment-friendly growth regulator.

Putrescine (Put), gibberellic acid (GA3), and salicylic acid (SA) are involved in improving fruit growth and development. This is the first study investigating the effect of 1 mM Put, 100 mg L-1 GA3, and 100 mg L-1 SA on Phoenix dactylifera, cv. Zaghloul fruits. The experiment was conducted in a completely randomized block design during two successive seasons and five treatments [control (distilled water spray), Put, Put + GA3, Put + SA, and Put + GA3 + SA] were sprayed at the Hababouk (cell division) stage and Kimri [unripe green (cell elongation)] stage. Our results showed that all treatments significantly improved the yield and quality of ‘Zaghloul’ fruit by increasing the dry matter, crude fiber, ash, total soluble solids, (reducing, non-reducing, and total soluble) sugars, carbohydrate, protein, nitrogen, phosphorus, potassium, calcium, magnesium, sodium, zinc, iron, and manganese content as well as the peroxidase and catalase activity. Compared with the control treatment, exogenous applications also enhanced the amino acid (glutamic acid, aspartic acid, proline, glycine, alanine, arginine, cysteine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, serine, threonine, tyrosine, valine) acquisition and phytohormone (indole-3-acetic acid, cytokinins, GA3, SA) content, while decreasing the percentage of moisture, total acidity, total phenols, and tannins. The novel evidence indicates that among all treatments, application of diamine (Put), in combination with phytohormones (GA3 and SA), has the greatest effect on improving ‘Zaghloul’ fruit yield by up-regulating the nutrient acquisition, sugar accumulation, amino acid profile, antioxidant response, and phytohormone performance. These findings support the use of Put in conjunction with GA3 and SA to improve fruit yield and quality.
