“…It is well known that the chlorophyll fluorescence parameter is used to detect and quantify chilling stress by means of changes induced in PSII. F v /F m , as a kind of chlorophyll fluorescence parameter, can be used as an important indicator of injury to PSII (Rizza et al, 2001;Lu et al, 2003;Tambussi et al, 2004;Baker, 2008;Liu et al, 2013;Zhou et al, 2015). Additionally, the present study showed that the application of Spd and SNP significantly decreased chilling-induced electrolyte leakage, compared to the chilling treatment alone.…”

Polyamines (PAs) and nitric oxide (NO) are vital signals in modulating plant response to abiotic stress. However, to our knowledge, studies on the relationship between NO and PAs in response to cold stress in tomato are limited. Accordingly, in this study, we investigated the effects of putrescine (Put) and spermidine (Spd) on NO generation and the function of Spd-induced NO in the tolerance of tomato seedling under chilling stress. Spd increased NO release via the nitric oxide synthase (NOS)-like and nitrate reductase (NR) enzymatic pathways in the seedlings, whereas Put had no such effect. Moreover, H 2 O 2 might act as an upstream signal to stimulate NO production. Both exogenous NO donor (sodium nitroprusside (SNP)) and Spd enhanced chilling tolerance in tomato, thereby protecting the photosynthetic system from damage. Compared to chilling treatment alone, Spd enhanced the gene expressions of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX), and their enzyme activities in tomato leaves. However, a scavenger or inhibitor of NO abolished Spd-induced chilling tolerance and blocked the increased expression and activity due to Spd of these antioxidant enzymes in tomato leaves under chilling stress. The results showed that NO induced by Spd plays a crucial role in tomato's response to chilling stress.

“…12 For Arabidopsis thaliana as well as in many other plant species, the chlorophyll fluorescence parameter F v /F m that is widely used as a proxy of the maximum quantum efficiency of PS II photochemistry was found to be highly correlated with low temperature tolerance. [21][22][23][24][25] However, F v /F m measurements overestimates the cold tolerance in Rhododendron ferrugineum L. by 5 °C. 26 Low temperature tolerance of various wheat cultivars was tested using non-imaging fast chlorophyll fluorescence induction kinetics, often called JIP tests.…”

“…Variable fluorescence (Fv) was calculated by subtracting F 0 from Fm. The Fv/Fm ratio measures the efficiency of excitation energy capture by open PSII reaction centers, representing the maximum capacity of light-dependent charge separation in PSII (Rizza et al, 2001).…”

This research was carried out in 2014 at the Research Farm of the University of Tabriz, Iran. The experiment was arranged as split plot on the basis of randomized complete block with three replicates to assess the effects of four irrigation intervals (irrigations after 60, 80, 100 and 120 mm evaporation) on physiological and agronomical traits of three cultivars of maize (Zea mays L.; 'SC704', 'NS640', 'DC303': late, mid and early maturing, respectively). Irrigation intervals and maize cultivars were assigned to the main and sub-plots, respectively. Leaf temperature of all maize cultivars significantly increased, but chlorophyll content index, maximum efficiency of photosystem II, number of grains per plant, 1000 grain mass, plant biomass, grain yield and harvest index significantly decreased with increasing irrigation intervals. Late maturing cultivar ('SC704') was superior in all studied traits, followed by mid ('NS640') and early ('DC303') maturing cultivars. It was concluded that water limitation can potentially reduce performance of maize cultivars in the field, but the extent of this reduction depends on genotype and severity of stress.Key words: chlorophyll content; leaf temperature; maize; photosystem II; drought stress IZVLEČEK USPEVANJE SORT KORUZE (Zea mays L.) V RAZMERAH SUŠNEGA STRESARaziskava je bila opravljena v sezoni 2014 na Research Farm of the University of Tabriz, Iran. Poskus je bil zasnovan kot poskus z deljenkami na osnovi popolnega naključnega bločnega poskusa s tremi ponovitvami za ovrednotenje učinkov štirih načinov namakanja (namakanje po 60, 80, 100 in 120 mm evaporacije) na osnovi fizioloških in agronomskih lastnosti treh sort koruze (Zea mays L.; 'SC704', 'NS640', 'DC303': zgodnje, srednje in pozno dozorevajoča sorta). Načini namakanja so bili vrednoteni na glavnih ploskvah, sorte koruze na podploskvah. Temperatura lista je pri vseh sortah značilno naraščala z večanjem intervala namakanja, lastnosti kot so indeks vsebnosti klorofila, maksimalna učinkovitost fotosistema II, število zrn na rastlino, masa 1000 zrn, biomasa rastlin, pridelek zrnja in žetveni indeks pa so se z večanjem intervala namakanja značilno zmanjšale. Pozno dozorevajoča sorta ('SC704') je bila v vseh preučevanih lastnostih najboljša, sledili sta ji srednje ('NS640') in zgodaj ('DC303') dozorevajoči sorti. Ugotovljeno je bilo, da pomanjkanje vode lahko potencialno zmanjša uspevanje koruze, a je obseg zmanjšanja odvisen od genotipa in jakosti stresa.
