![]() The Plant is stressed from its roots because heirloom plants roots are bigger designed to produce until the first frost. Google Scholar Visser EJW, Blom CWPM, Voesenek LACJ. Hormonal interplay during adventitious root formation in flooded tomato plants. I checked my container, where I am trying out growing a Tomato Plants in a container as this year experiment with an Heirloom Plant and a Hybrid and that Heirloom Plant looks the same. Adventitious root primordia were constitutively present on the stem and internodes of this species (i.e. In the last picture, the affected plant is on the left. The frequency of lateral root initiation in tomato seedling roots is increased over eightfold in response to 1.6 M -naphthaleneacetic acid and GUS activity was observed in both lateral and adventitious root initials, including very early initials, and persisted until shortly after the lateral emerged from the parent tissue. ![]() Third is the entire obsession, I mean garden. So I've removed the automatic irrigation gadget from this Earthbox (which happened to be dripping today, perhaps because I moved it to an uneven surface), dumped most of the water from the reservoir, and removed some of the plastic cover.Īnyone have any thoughts about potential root damage?įirst pic is affected stem, second is top of that plant, and another in the same box. We all learned by doing and I doubt that no matter what, this particular tomato is going to be producing any good tomatoes for you as it is too stressed to recover.". Ethylene entrapment by water may represent the rst warning signal to the plant indicating waterlogging. not sure what is in the container but how is the drainage? The bumps on the stem are called root initials or adventitious roots and while they can be normal, they are often a sign of over watering and poor drainage that damages roots. Although tomato (Solanum lycopersicum) is known for its sensitivity to waterlogging, its ability to produce adventitious roots (ARs) increases plant survival when the level of oxygen is decreased in the root zone. "This looks like a stressed/drowned tomato. A molecular marker for lateral root initiation: the RSI-1 gene of tomato (Lycopersicon esculentum Mill) is activated in early lateral root primordia Abstract. I've also read comments about root primordia or initials, like this quote from KarenO I've been setting up the automatic watering set-eup on my Earthboxes, and this one was dripping today. ![]() Today I noticed these white bumps on the stems, and recalled it might be "oedema" (I LOVE that spelling!), and reflect overwatering. I've been growing tomatoes for a long time, and I probably would have ignored this in the past, but these plants have been unusually pristine. I have probably lost my mind, because I am inspecting these plants 5 times a day.
