“…4a). It should be pointed out that increase in W k with an elevated K step around 300 s is commonly accepted as a specific indicator of injury on OEC, although increased V k is also a reasonable candidate (Wen et al, 2005;Yang et al, 2007;Li et al, 2009;Brestic et al, 2012;Yan et al, 2013). However, just increased V k was observed in this study ( Fig.…”

“…We believe that K phase was concealed in the elevated J phase at high temperature, and V k is more proper to indicate heat-induced injury on OEC on the premise of elevated J step. In addition, OEC is often recognized as the most heat-sensitive PSII component (Lu and Zhang, 2000;Allakhverdiev et al, 2008;Li et al, 2009), but earlier inhibition on electron transport beyond Q A occurred in this study. The underlying reason is that heat stress was carried out under growth light not in dark, and the block of electron transport from PSII may be a self-protection way by reducing the possibility of PSI photoinhibition (Sonoike, 2011;Zhang et al, 2011).…”

a b s t r a c tIn order to explore the response of photosynthetic electron transport chain to heat stress, chlorophyll a fluorescence and modulated 820 nm reflection transients were examined in the leaves of Jerusalem artichoke (Helianthus tuberosus L.). J step was elevated at 43• C, suggesting that electron transport beyond primary quinone electron acceptor of photosystem II (Q A ) was inhibited. I step was elevated at 45• C due to the lowered plastoquinol re-oxidation rate. Significant decrease in the Q A reducing reaction centers per photosystem II (PSII) antenna chlorophyll and marked increase in relative variable fluorescence intensity at 300 s also occurred at 45• C, indicating that the electron transport chain from PSII donor side to Q A was injured. Overall, the fragment between Q A and plastoquinol is the most susceptible to heat in the electron transport chain before photosystem I (PSI). The maximal photochemical capacity of PSI was not affected by heat stress even at 48• C, and the interaction between PSII and PSI become unbalanced, when temperature rose to 45• C. At 45 • C, prolonged PSI oxidation occurred in the expanding leaves because of the inhibited electron donation from PSII, however, PSI oxidation amplitude decreased in the expanded leaves. We infer that electron transport chain of PSI acceptor side is more sensitive to heat stress than the chain before PSI in the expanded leaves. Therefore, electrons in PSI reaction center could not be efficiently drained to the downstream at high temperature, and then PSI oxidation was blocked.

“…Phenotipic distance matrix based on 16 OIV descriptors was computed by NTSYSpc version 2.10s software (Rohlf, 2000) using DICE coefficient of similarity (Nei, 1978, Li et al, 2009). The distance matrix was then processed using the UPGMA algorithm, which was then visualized as the dendrogram by the same software.…”

In Herzegovina, different genotypes of grapevine are called the same, and the origin of these cultivars is mainly unexplored. Two groups of autochthonous cultivars are grown. The first group consists of more widespread Žilavka and Blatina, and accompanying Bena, Krkošija, Dobrogostina and Trnjak, and the second one of less common cultivars that should be preserved from extinction. Considering the small number of studies on the comparison of different methods used for analyses of similarities and relatedness of grapevine germplasm, it was interesting to assess the use of morphological characterization with molecular markers in identification of cultivars in Herzegovina. The results indicate that a similarity coefficient had a broad value range for both methods. Both methods successfully in different ways differentiated all analysed varieties, and for complete and comprehensive identification of grapevine varieties should be use.

“…1). O-J-I-P transient has been accepted as a reliable and popular tool in photosynthetic research, especially to study PSII behavior in recent years (Wen et al 2005;Strauss et al 2007;Toth et al 2007;Yang et al 2007;Chen et al 2008;Rapacz et al 2008;Yan et al 2008Yan et al , 2011Li et al 2009;Mehta et al 2010;Rapacz et al 2010;Jedmowski et al 2013). O, J, I and P are a sequence of phases in the kinetics of fast fluorescence rise, and environmental stress often provokes the occurrence of K phase in this transient, suggesting the damage to oxygen-evolving complex in donor side of PSII (Strasser et al 2004).…”

Physiological adaptive mechanisms of plants grown in saline soil and implications for sustainable saline agriculture in coastal zone

et al. 2013

There is large area of saline abandoned and lowyielding land distributed in coastal zone in the world. Soil salinity which inhibits plant growth and decreases crop yield is a serious and chronic problem for agricultural production. Improving plant salt tolerance is a feasible way to solve this problem. Plant physiological and biochemical responses under salinity stress become a hot issue at present, because it can provide insights into how plants may be modified to become more tolerant. It is generally known that the negative effects of soil salinity on plants are ascribed to ion toxicity, oxidative stress and osmotic stress, and great progress has been made in the study on molecular and physiological mechanisms of plant salinity tolerance in recent years. However, the present knowledge is not easily applied in the agronomy research under field environment. In this review, we simplified the physiological adaptive mechanisms in plants grown in saline soil and put forward a practical procedure for discerning physiological status and responses. In our opinion, this procedure consists of two steps. First, negative effects of salt stress are evaluated by the changes in biomass, crop yield and photosynthesis. Second, the underlying reasons are analyzed from osmotic regulation, antioxidant response and ion homeostasis. Photosynthesis is a good indicator of the harmful effects of saline soil on plants because of its close relation with crop yield and high sensitivity to environmental stress. Particularly, chlorophyll a fluorescence transient has been accepted as a reliable, sensitive and convenient tool in photosynthesis research in recent years, and it can facilitate and enrich photosynthetic research under field environment.
