Considering the economic importance of the tomato and its nutritional benefits to human health, a study was made of how two different environmental factors (temperature and overall solar radiation) influence the nutritional quality of cherry tomatoes during the plant full production cycle. Solanum lycopersicum L. cv. Naomi plants were grown in an experimental greenhouse. Three fruit samples wer...

Iodine is a non-essential element for land plants, but considered as beneficial element, related to antioxidant capacity, environmental adaptations and improvement of plant growth. Salinity one the more recurrent abiotic stresses worldwide, seriously affecting vegetal production. The aim this work was evaluate iodine application (Q products® KIO3, Quimcasa de México, Naucalpan, Mexico) in straw...

OBJECTIVE To investigate the acaricidal activity of different extracts from Syzygium cumini (S. cumini) (Pomposia) againsst Tetranychus urticae Koch (T. urticae) and the biochemical changes in antioxidants enzymes. METHODS Six extracts of S. cumini (Pomposia) at concentrations of 75, 150 and 300µg/mL were used to control T. urticae (Koch). RESULTS The ethanol extract showed the most efficie...

Photoperiod and nutrient nitrogen (N) supply influence the growth, development, and productivity of crops. This study examined the physiological, biochemical, and morpho-anatomical traits of NA5 and NA9, two barley cultivars with contrasting photoperiod lengths, under the combined treatment of photoperiod regime and N supply. Under long photoperiod, high N supply decreased net photosynthesis; d...

Melatonin, an indoleamine molecule, regulates a wide range of physiological functions during the growth, morphogenesis, and response plants to abiotic stresses. We examined effect exogenous melatonin application (5, 10, 20 mg·L-1) on growth antioxidant enzyme activity Kimchi cabbage under high temperature (air 32/26°C) drought stress (soil moisture 20–24%) conditions. Application 10 mg·L-1 alle...

Peel browning disorder has an enormous impact on the exterior quality of 'Huangguan' pear whereas the underlying mechanism is still unclear. Although different methods have been applied for inhibiting the peel browning of 'Huangguan' pear, there are numerous issues associated with these approaches, such as time cost, efficacy, safety and stability. In this study, to develop a rapid, efficient a...

Heavy metal stress induced alterations in the activities of several representatives of the enzymatic antioxidant defense system such as guiacol peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) were comparatively studied in barley seedlings treated by Zn and Cd. Although roots were the main sites of metal accumulation, the oxidative damage was detrimental mainly in the leaves. Our...

Lilium species with ornamental, edible, and medicinal values are distributed all over the world. Little is known about responses of genotypes to waterlogging stress. hybrid 'Brindisi' was used study physiological roots, bulbs, leaves 1, 2, 4, 8, 13 d Results showed that stress seriously hindered transport nutrients from bulbs stems leaves. The indicators could be divided into two categories. fi...

WRAB18, an ABA-inducible protein belongs to the third family of late embryogenesis abundant (LEA) proteins which can be induced by different biotic or abiotic stresses. In the present study, WRAB18 was cloned from the Zhengyin 1 cultivar of Triticum aestivum and overexpressed in Escherichia coli to explore its effects on the growth of E. coli under different abiotic stresses. Results suggested ...
