Interactive effects of NaCl salinity and elevated atmospheric CO2 concentration on growth, photosynthesis, water relations and chemical composition of the potential cash crop halophyte Aster tripolium L.

Canola seed germination and seedling initial growth under conditions of salinity

“…Changing membrane permeability can lead to solute leaching, reducing mitochondrial efficiency as for consequence ATP production and energy for seed germination (NONOGAKI et al, 2010) and seedling growth. (GEISSLER et al, 2009) and these are the major reserves sources in canola seeds, because typically canola seed has an oil content ranging from 35-45% and a minimum of 35% protein (AOF, 2007), probably, this cause negative effects on seedling growth because the energy available for this process is reduced. Is important also to highlight that in plant cells, toxicity is resolved by vacuolar compartmentalization (QIU et al, 2007), and recent reports suggest that Na + can be bound in starch granules (KANAI et al, 2007), although, this compartmentalization would be energy intensive, while binding sodium to starch would prevent the starch from being used to provide energy for germination (ZHANG et al, 2010) as for seedling growth.…”

Impact of Seawater Salinity on Ultrastructure of Chloroplasts and Oleosomes in Relation to Fat Metabolism in Flag Leaf of Two Wheat Cultivars During Grain-filling

“…Salinity stress resulted in noticeable alterations and swelling of thylakoidal structures as reported in case of Nicotina bigelovii [7] and wheat [1,8] Geissler and others [9] showed that under saline conditions, the chloroplasts of Aster tripolium plants were partially horseshoe-shaped, their thylakoid membranes showed dilations, the spaces between the membranes looked swollen and un-dilated thylakoid areas were developed. In particular, the number of grana stacks was considerably reduced.…”

Role of Exogenous 24-Epibrassinolide in Enhancing the Salt Tolerance of Wheat Seedlings

“…Salinity causes the accumulation of low molecular weight compounds called compatible solutes such as proline and glycine betaine (Chen et al, 2007). High salinity adversely affects growth, physiology and productivity by increasing ion toxicity, and decreasing protein synthesis and lipid metabolism (Geissler et al, 2009). In addition, further investigations regarding the approaches to alleviating salinity toxicity are needed.…”
