Emissions of green leaf volatiles and terpenoids from Solanum lycopersicum are quantitatively related to the severity of cold and heat shock treatments

The influence of soil salinity on volatile organic compounds emission and photosynthetic parameters of Solanum lycopersicum L. varieties

“…In our studies we found only (Z)-3-hexenol which is emitted from tomato under osmotic stress compared with the previous articles which reported four or even nine different C5 and C6 green leaf volatiles, respectively [21,16]. The emission became significant even at 100 mM NaCl in soil but was very low for control plants.…”

“…The emissions consisted of α-pinene, camphene, 2-carene, α-phellandrene, limonene, β-phellandrene, (E)-β-ocimene and terpinolene as have been previously reported by Jensen et al [21] and Copolovici et al [16]. The composition was the same for stressed and control plants and could be due to cellular damage or enhanced permeability of barriers of terpene-containing structures.…”

“…The composition was the same for stressed and control plants and could be due to cellular damage or enhanced permeability of barriers of terpene-containing structures. The same emissions have been described for B. cinerea infection of tomato which has been associated with inoculation damage [21] as well as for cold and heat stress [16]. It has been shown that the terpene emissions from storage pools scale exponentially with temperature due to the permeability changes of the glandular trichomes [16,34].…”

“…The same emissions have been described for B. cinerea infection of tomato which has been associated with inoculation damage [21] as well as for cold and heat stress [16]. It has been shown that the terpene emissions from storage pools scale exponentially with temperature due to the permeability changes of the glandular trichomes [16,34]. In case of osmotic stress, the trichomes developed irregularly in Nicotiana tabacum L. [35] and even showed an overall density increase in Madia sativa [36,37].…”

“…The volatile compounds emitted from tomatoes have not been studies thoroughly. The green leaf volatile emission has been reported for tomato plants inoculated with necrotrophic fungus Botrytis cinerea [21], after feeding by cotton leaf worms, Spodoptera littoralis [22] and as a result of cold and heat stress [16]. The aim of this paper is to evaluate different tomato varieties (including wild species) for their tolerance to soil salinity and to find if some volatile organic compounds can be used for rapid screening of tomato varieties for salinity stress resistance.…”
