Marigold has special importance and application in landscape designing. Nowadays, various species and cultivars of this plant are grown in many climates, where different environmental stresses such as freezing, salinity and drought can lead to vegetative disorders. This study was carried out to investigate the interactions between salinity and ammonium nitrate on seed germination, vegetative gr...

Effect of salinity on sprouting water uptake, ion uptake and metabolic efficiency of wheat seeds in the variety kanchan were studied in Jaydebpur. The treatments were 0, 4, 8, 12 and 16dS salinity level. The experiment was set in CRD with four replications. There were 50 seeds per petridish. Seeds were moistened with saline solution. Germination was recorded up to 72 hours with an interval of 1...

Salinity reduces substrate water potential, thereby restricting water and nutrient uptake by plants; salinity may also cause ionic imbalance and toxicity. Because substrate salinity fluctuates through the growing season, a plant may be exposed to different salinity levels, at various stages of development, with potentially significant consequences on population dynamics. Here, we present the re...

abstract various resistances to salinity are due to plants genetically variations, and selection on the basis of one factor will not be a suitable criterion in measurement of resistance to salinity, therefore in choosing resistant varieties, it is necessary to notice to a set of resistant indexes to salinity, creating changes in physiology, anatomy and morphology of plant species. this research...

Application of grafting technique could be an approach for increasing salinity resistance of tomato cultivars. To assess the impact of grafting on resistance of tomato to salinity, two varieties of conventional tomato called Hamra and Kevin were grafted on a salt-resistant base, called AR-9704, using chisel grafting method, and were grown in the greenhouse, using a hydroponic system, under thre...

The present work describes the effect of different salinities on the functional morphology of the P. argentinus hepatopancreas and analyses the tissue recovery after re-acclimation to freshwater. Adult prawns of both sexes at sexual rest were collected from a tributary of the Mar Chiquita coastal lagoon. The prawns were acclimated in aquaria to four salinity conditions: 0 (control), 8, 16 and 2...
