Rootstock Performance of Cherry Tomatoes Grown in Soil Cultivation: Evaluation of Growth, Yield, and Photosynthesis

Grafted seedlings have widely been used in fruit vegetables such as tomatoes order to increase productivity by acquiring resistance environmental stress and soil-borne diseases. This study was conducted assess the performance of rootstocks comparatively analyzing growth, yield, photosynthetic efficiency, measuring chlorophyll fluorescence, cherry grown soil cultivation. The tomato variety ‘Nonari’ scion. domestic rootstock cultivars ‘Powerguard’, ‘IT173773’, ‘20LM’, a control cultivar ‘B-blocking’ were grafted with When using ‘20LM’ ‘Nonari’, yield 15% higher than cultivar, index based on absorption (PIABS), which is an plant vitality, much 3.260 even low temperature period. maintained vigor balanced growth until late harvest because its efficiency high when exposed cold early stage. strength non-grafted decreased 7.3mm at 80 days after planting. had greater tolerance they stronger roots. In contrast, plants damaged cold, inhibited led decrease yield. ‘Powerguard’ ‘IT173773’ scion, low, might due stage; fluorescence OJIP transients (OJIP curves) lower those other plants. There significant relationship between fluorescence. Therefore, can be screen rootstocks.
