Does grafting provide tomato plants an advantage against H2O2 production under conditions of thermal shock?

چکیده
Non-grafted tomato plants (Lycopersicon esculentum L. cv. Tmknvf2) and grafted tomato plants (L.esculentum L. cv. Tmknvf2¿L.esculentum L. cv. RX-335) were grown for 30 days at three different temperatures (10æC, 25æC and 35æC). In the leaves of these plants, the enzymatic activities of SOD, GPX, CAT, APX, DHAR and GR were analysed, as were the concentrations of total H2O2, ascorbate and glutathione as well as foliar DW. Regardless of whether the plant was grafted or not, our results indicate that the thermal stress occurred

Effect of grafting on eggplant leaf gas exchanges under mediterranean greenhouse conditions
Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes in leaf photosynthetic capacity of a hybrid eggplant Solanum melongena L., cv. Rima (R), widely used in Greece] when grafted on tomato rootstocks known for their resistance to n...

The effects of exogenous abscisic acid (ABA) and its two agonists, Sulfacetamide (Sa) and Sulfasalazine (SS) on tolerance of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under drought stress were studied. Eight-week plants were treated with ABA (25 and 50 mg/L), Sulfacetamide (Sa) (25, 50 and 100 mg/L) and Sulfasalazine (SS) (25, 50 and 100 mg/L). Solutions were sprayed daily and samp...

Reactive oxygen species (ROS) generation in tomato plants by Ralstonia solanacearum infection and the role of hydrogen peroxide (H2O2) and nitric oxide in tomato bacterial wilt control were demonstrated. During disease development of tomato bacterial wilt, accumulation of superoxide anion (O2 (-)) and H2O2 was observed and lipid peroxidation also occurred in the tomato leaf tissues. High doses ...

Drought causes an increase in some gene expression in plant tissues such as plasma membrane intrinsic proteins type 1 (PIP1), 9-cis-epoxycarotenoid dioxygenase (NCED) SlAREB1. The effects of exogenous abscisic acid (ABA) and two sulfonamide compounds, namely, sulfacetamide (Sa) and sulfasalazine (SS) were studied on gene expression of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under...
متن کاملCan grafting in tomato plants strengthen resistance to thermal stress?
Grafted and non-grafted tomato plants were grown at 25 and 35 ◦C for 30 days. In tomato leaves we analysed total phenols, o-diphenols, enzymatic activities (PAL, PPO and GPX) and dry weight. Our results indicate that heat stress in both grafted and non-grafted tomato plants occurred at 35 ◦C and resulted in (1) increased PAL activity, (2) increased total phenols and o-diphenols, (3) decreased P...
