Tolerance to salinity in Jatropha curcas are genotype-dependent

Abstract

Tolerance to salinity in Jatropha curcas are genotype-dependent A tolerância à salinidade em pinhão manso é dependente do genótipo

Comparative analysis of salt-induced changes in the leaves proteome of two contrasting Jatropha curcas genotypes

“…The all experiments was performed under randomized block design containing two genotypes (CNPAE183, and CNPAE218), one saline concentrations (750 mM L -1 of NaCl) added to Hoagland nutrient solution and 4 replicates. The saline concentration used in this study merged after two previously study of our research group [10,11]. Corte-Real, Miranda [10] describes that while CNPAE183 readily recovered our net photosynthesis after salt stress alleviation, CNPAE218 never recovered our net photosynthesis, since even after 914 hours of salt alleviation its net photosynthesis were negative or almost zero.…”

To effect of comparison, 750 mM L -1 of NaCl, corresponding to 46.8 dS m -1 of electrical conductivity, obtained after linear regression between [NaCl] and its respective electrical conductivity.…”

“…Originally, this study was designed to compare six different genotypes of Jatropha curcas. However, based in the previous study of our research group [10,11],…”

“…The performance of J. curcas under salt stress has been the target of several physiological studies [9][10][11][12][13][14]. Recently, some studies [10][11][12] have been described J. curcas genotypes more tolerant do salinity than others.…”

“…The performance of J. curcas under salt stress has been the target of several physiological studies [9][10][11][12][13][14]. Recently, some studies [10][11][12] have been described J. curcas genotypes more tolerant do salinity than others. Although, J. curcas is a relatively drought-tolerant plant [15][16][17], it is also considered a salt-sensitive one [12,18,19], while others classify it as moderately tolerant to salt stress [13].…”
