A field experiment was conducted during 2006-2007 and 2007-2008 seasons at Herbal garden, Rajendranagar, Hyderabad, India to study the influence of exogenous application of CPPU and GA yield, 3 fruit quality characters and seedlessness in watermelon. The experiment consists of 12 treatments (CPPU-50 ppm (T ), CPPU-100 ppm (T2), CPPU-200 ppm (T3), GA -100 ppm(T ), GA -200 ppm(T ), CPPU 50 ppm + ...

N-(2-Chloro-4-pyridyl)-N'-phenylurea (CPPU) is a highly active cytokinin-like plant growth regulator that promotes chlorophyll biosynthesis, cell division, and cell expansion. It also increases fruit set and accelerates fruit enlargement. However, there has been no report about the effect of CPPU on fruit development and its physiological mechanism in macadamia. In this study, we investigated t...

Bunch thinning is one of the main cultural practices that enhance fruit quality. Hand thinning of date palm bunches is tedious and can not be implemented on a large scale. In this study, the cytokinin derivative CPPU [Nchloro4 pyridyl) N-phenyl urea] and fine mist of water were used 2 days prior pollination as thinning agent via reducing fruit set of Barhi and Lulu cultivars in two separate stu...

The effects of N-benzyladenine (BA) and N-(2-chloro-4-pyridyl)-N-phenylurea (CPPU) in combination with gibberellic acid (GA3, 100 mg l ) on berry setting and development and on the endogenous level of polyamines (PAs ) were investigated in order to elucidate the role of PAs in the setting and development of GA3-induced seedless grape berries affected by cytokinins. BA stimulated berry developm...

Fruit set of plants largely depends on the biosynthesis and crosstalk of phytohormones. To date the role of cytokinins (CKs) in the fruit development is less understood. Here, we showed that parthenocarpic fruit could be induced by 1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU, an active CK) in tomato (Solanumlycopersicum cv. Micro-Tom). The fresh weight of CPPU-induced parthenocarpic fruits was co...

Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on ...

The limitations in current understanding of the molecular mechanisms underlying fruit response to the application of plant growth regulators have increasingly become major challenges in improvement of crop quality. This study aimed to evaluate the response of strawberry to the preharvest application of exogenous cytokinin known as forchlorfenuron (CPPU). Postharvest internal and physiological q...

Cytokinins (CKs) are thought to play important roles in fruit development, especially cell division. However, the mechanisms and regulation of CK activity have not been well investigated. This study analysed CK concentrations and expression of genes involved in CK metabolism in developing tomato (Solanum lycopersicum) ovaries. The concentrations of CK ribosides and isopentenyladenine and the tr...

Forchlorfenuron (CPPU) has been used worldwide, to boost size and improve quality of various agricultural products. CPPU its metabolites are persistent have detected frequently in fruits, water, sediments, organisms aquatic systems. Although the public became aware through exploding watermelon scandal 2011 Zhenjiang, China, little was known potential effects on environment wildlife. In this stu...
