Plant material
Tomato (Solanum lycopersicum L. ‘Moneymaker’) seeds were
germinated in potting soil in a growth chamber (24°C, 12/12 light/dark).
Five days after emergence, seedlings were transplanted to pots
containing a 3:1 (v/v) mixture of sand and sieved potting soil
(Structural Type 1, Snebbout). Seedlings were watered three times a week
and fertilized weekly with 30 ml of fertilizer (Soluplant NPK
19-8-16+4MgO+ME, Haifa Chemicals, 1 g l-1). Rice
(Oryza sativa L. ‘Nipponbare’) seeds (GSOR-100, USDA) were grown
as in Nahar et al. (2011).
