Adventitious root formation of different varieties of tomato (Solanum lycopersicum L.) applied with plant growth regulators under flooded condition [manuscript]
(2020) John Jeric S. Leaño
This study evaluated the effects of Auxin and Cytokinin on growth and survival of different varieties of tomato under flooded conditions. Specifically, it aimed to evaluate varietal difference in adventitious root formation of tomato under flooded condition and to determine the effects of auxin and Cytokinin in adventitious root formation and elongation of flooded tomato. The treatment used were water regime as main plot WR1-0 day (non-waterlogged/control), WR2- 2 days (waterlogged) (Or until wilting. Variety as subplot VI- Diamante Max, V2-Rosanna, and V3-Apollo. Combination of auxin and Cytokinin as sub-sub plot C1-Untreated Control, C2- 0% auxin + 5% Cytokinin, C3 – 0% Auxin + 10% Cytokinin, C4- 0.125% Auxin + 0% Cytokinin, C5-0.125% Auxin + 5% Cytokinin, C6- 0.125% Auxin + 10% Cytokinin, C7- 025% Auxin + 0% Cytokinin, C8- 025% Auxin + 5% Cytokinin, C9- 025% Auxin + 10% Cytokinin. Treatments were arranged in split-split plot design in RCBD. Based on the results, combination of auxin and cytokinin did not improve the growth (plant dry weight) of different tomato varieties subjected to flooded condition. No varietal difference was found in terms of adventitious root formation 9number, length and dry weight) indicating that Diamante Max, Rosanna and Apollo have similar capacity.
