... defined as any environmental variable, which can induce a potentially injurious strain in plants. The concept of optimal growth conditions is a fundamental principle in biology. Since living ... ion contents in plants under salt stress revealed that halophytes accumulate salts whereas glycophytes tend to exclude the salts (Zhu, 2007). High salinity affects plants in two main ways: high ... induction of Φ PSII and a large increase of NPQ. The obtained results indicate of an increase in sink strength in the vicinity of the wound.
