“…These results were agreed with those obtained in a previous study in which BA-treated leaves had higher specific and dry weights, and the chlorophyll and carotenoid contents were greater than water controls (Adedipe et al, 1971). The increase in photosynthetic pigments has been observed in the mustard plant due to exogenous IAA treatment, that led to an increase in plant growth parameters as well as yield due to increase in photosynthetic rate (Hayat et al, 2001).…”

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.

“…Gibberellins also play an important role in the tolerance of plant to salinity by enhancing plant growth and yield (Hayat et al 2001;Siddiqui et al 2008). An osmotic stress, sufficient to inhibit germination, has been reported to cause a reduction in gibberellins content (Kaur et al 1998).…”

Salinity is one of the major abiotic stresses limiting crop growth and yield. This study investigated the underlying mechanisms of Trichoderma asperellum Q1 in promoting cucumber growth under salt stress, including the abilities of the strain to solubilize phosphate and to produce phytohormone. The results showed that T. asperellum Q1 could solubilize inorganic or organic phosphate and the activities of phosphatases and phytase could be detected in the culture supernatant. In hydroponic experiments, the growth of cucumber seedlings was increased in the hydroponic system treated by culture filtrate of strain Q1 with tricalcium phosphate or calcium phytate under salt stress. This strain also exhibited the ability to produce indole acetic acid (IAA), gibberellic acid (GA) and abscisic acid (ABA) in liquid medium without any inducers. The levels of those three phytohormones in cucumber seedling leaves also increased after inoculated with this strain, along with increased root growth and root activities of the plant. These results demonstrated the mechanisms of T. asperellum Q1 in alleviating the suppression effect of salt stress involving the change of phytohormone levels in cucumber plant and its ability of phosphate solubilization.

“…In leguminous crops, the number of pods per plant and total seed yield increases after the application of exogenous BRs (Hayat and Ahmad 2003;Ramraj et al 1997;Rao et al 2002;Takematsu and Takeuchi 1989;Vardhini and Rao 1998). Growth and seed yield of mustard or rapeseed plants is also promoted by their treatment with BRs (Hayat et al 2000(Hayat et al , 2001bRamraj et al 1997;Rao et al 2002;Takematsu and Takeuchi 1989); the same applies for seed yield in cotton (Ramraj et al 1997).…”

The effect of brassinosteroids on the morphology, development and yield of field-grown maize

et al. 2010

The response of two field-grown inbred lines of maize (Zea mays L.) and their F1 hybrid to the application of 10 -8 -10 -14 M solutions of 24-epibrassinolide or synthetic androstane analogue of castasterone in V3/4 and V6/ 7 developmental stages was followed during the vegetative and early reproductive phases of plant development. Brassinosteroids (BRs) significantly affected (either positively or negatively, depending on the genotype and the developmental stage they were applied) the height of plants during the early weeks after their application, but not the final plant height nor the number of leaves. Spraying of plants with BRs in V3/4 developmental stage usually also increased the length of the 7th to 10th leaf, whereas the application in V6/7 developmental stage had the opposite effect. The beginning of the reproductive phase of plant development and the course of flowering was strongly influenced by the application of BRs. Treatment of plants in V3/4 stage delayed and treatment of plants in V6/7 stage advanced the dates of anthesis and silking, regardless of the type of BR used, its concentration or plant genotype. The influence of BRs on the development of the secondary ear was the least pronounced in the F1 hybrid; in both inbred lines it strongly depended on the concentrations of BRs used. Various yield parameters were also affected by treatment of plants with BRs, but this effect depended on the developmental stage during which the application of BRs occured, the plant genotype, the type of BR and its concentration.
