Summary
Growth and ascorbic acid content of English spinach (Rumex patientia L.) were determined during a period of 7 weeks in the phytotron and also in the open field in relation to temperature. As compared with constant warm temperature, a low average temperature in the phytotron resulted in significantly increased plant weights and increased ascorbic acid contents. The results of the open field studies showed great deviations in plant weight and ascorbic acid content, due to metereological conditions. Generally, the content of ascorbic acid in spinach increased with the growth of the plants.
