Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...

Abstract Phosphorus (P) is obtained by plants as phosphate (Pi) from the soil and low Pi levels affects plant growth development. Adaptation to condition entails sensing internal external translating those signals molecular morphophysiological changes in plant. In this review, we present findings related local systemin with focus mechanisms behind root system architectural impact of hormones ep...

In plants, multistep component systems play important roles in signal transduction in response to environmental stimuli and plant growth regulators. Arabidopsis contains six nonethylene receptor histidine kinases, and, among them, AHK1/ATHK1, AHK2, AHK3, and CRE1 were shown to be stress-responsive, suggesting their roles in the regulation of plant response to abiotic stress. Gain- and loss-of-f...

Plant cells in tissues experience mechanical stress not only as a result of high turgor, but also through interaction with their neighbors. Cells can expand at different rates and in different directions from neighbors with which they share a cell wall. This in connection with specific tissue shapes and properties of the cell wall material can lead to intricate stress patterns throughout the ti...

The microorganisms are in the different of habitants, they are also on the surface of seeds of cultivated plants. Quantitive and generic composition of saprophagan air-plant microflora is very diversified and still it is not well known. Microbial populations of seeds depend on numerous factors. Chemical constitution of seeds and different abiotic environment factors have the significant influen...

Naturally occurring polyamines in plants have been implicated in cell division, metabolic activity, floral initiation, and fruit development. The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilizat...

Over the last few years, we have been experimenting with the idea of applying ethylene-releasing plant growth regulators (PGRs) to the rootzone as a substrate drench. This is a rather radical idea for floriculture production overall and flowerbulb forcing in particular. In this newsletter, we’ll review ethylene as a growth regulator, discuss the commercialy available ethylenereleasing PGRs and ...

Abstract Kandelia candel (L.) Druce is one of the rare mangrove species in Indonesia. Additionally, rehabilitation requires effective and efficient methods. Accelerating growth using vegetative propagation, specifically hypocotyl cutting, necessary. The objectives this study were to investigate scientific literature on use K . for Indonesia analyze seedling from cuttings. Scientific was collect...
