The circadian clock, synchronized by daily cyclic environmental cues, regulates diverse aspects of plant growth and development and increases plant fitness. Even though much is known regarding the molecular mechanism of circadian clock, it remains challenging to quantify the temporal variation of major photosynthesis products as well as their metabolic output in higher plants in a real-time, no...

In this study, 12 taxa from the Chlorophyta, Phaeophyta and Rhodophyta were collected from different depths at Gemlik-Karacaali and Erdek-Ormanlı. A total of 175 specimens from these divisions were used to determine Total Protein (TP), Total Soluble Carbohydrate (TSCH) and Chlorophyll a (Chl a), Chlorophyll b (Chl b), Chlorophyll c (Chl c), total carotenoid (Car) contents and Chl b/Chl a, Chl c...

this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

to evaluate and compare the chlorophyll content, carotenoid, protein, peroxidase and polyphenol oxidase in different barley species in iran, 49 genotypes belonging to 5 barley species were employed in a completely randomized design with three replications in greenhouse conditions. a high level of within and between species variation was detected. in all the species, significant positive correla...

The effects of single and combined growth regulator treatments of indole-3-acetic acid (IAA), gibberellic acid (GA3) and coconut milk on plant height, yield, chlorophyll and vitamin contents of Abelmoschus esculetus L and Solanum gilo L were investigated. The single growth regulator treatments consisted of 50mg/L, 100 mg/L of IAA and GA3 and 10%, 15% of coconut milk. In case of combined growth ...

The positive effect of melatonin on the function of the photosynthetic apparatus is known, but little is known about the specific mechanisms of melatonin's action in plants. The influence of melatonin on chlorophyll metabolism of 24-day-old Pisum sativum L. seedlings during paraquat (PQ)-induced oxidative stress was investigated in this study. Seeds were hydro-primed with water (H), 50 and 200 ...

cadmium as a heavy metal is also considered as a serious threat for the environment. this element is accumulated in soil through industrial processes as well as phosphate fertilizers and aggregates into the food chain.this study was conducted in order to investigate of different levels of cadmium effects on growth features of rapeseed(brassica napus l.) plants. root and shoot weight and height,...

nickel and cadmium are heavy metals with some hazards for plant metabolism. the impacts of nickel chloride (0, 400 and 800 μm) in the presence of vitamin b complex (0, 30 and 60 ml from pharmacy commercial stock) and the impacts of cadmium chloride (0, 100, 200, 300, 400, 500 and 600 μl from 100 µm stock) in pot and cadmium nitrate (0, 100, 200, 400, 800, 1600 and 3200 μl from 100 µm stock) in ...
