Abstract
Two experiments were carried out in private farm (Khatatba Minufiya Governorate) in winter of field 2016/ 2017and 2017/ 2018 seasons to evaluate the alteration of physiological and biochemical processes as well as yield and its quality of tomato plants (Solanum lycopersicum) grown under chilling stress (5-10°C at night). The nanobiostimulators used in this study were, NB compound contains (CPPU, BR and proline) used by two concentrations (NB1: 0.5 and NB2: 1.0 ml L), nano jasmonic acid (JA1: 5 and JA2: 10 ppm), and finally nano silicon (Si1: 2 and Si2: 3 mM) beside the control plants which sprayed with tap water. The treatments applied as foliar on tomato seedlings grown under low temperature at 45, 60 and 90 day after transplanting. The results were as following:- low temperature caused significant reductions in plant height, fresh and dry weight of leaves and branches as well as leaf area, chlorophyll content, antioxidant enzymes (PPO, PO and CAT), also reduced proline content and total sugars. Moreover significant reduction in early and total yield and firmness, TSS and Vit C, meanwhile increased chilling injury index (CI %.) Spraying NB1 and Si1 at low concentration caused a significant reduction in chilling injury index (CI) and increased significantly chlorophyll content, antioxidant enzymes (PPO, PO and CAT), proline content and total sugars. Meanwhile significantly reduced chilling injury index (CI). Moreover, nanobiodtimulators at low concentration caused a good performance for tomato plants with highly early yield (57, 48%) and (43, 40%) for NB1 & Si1 beside total yield (30, 37%) and (20, 23%) for NB1 & Si1, in both seasons respectively, also the same treatments had induction in firmness, TSS and Vit. C compared to the control plants.
