    Abstract

    Deep-seeding and ethylene were found to stimulate extension growth of the first internode of intact wheat (Triticum aestivum L.) seedlings in darkness. Seedlings of Hon Mang Mat emerged from much deeper in the soil than the seedlings of the other varieties used and their first internodes elongated to a much greater extent in response to ethylene. Carbon dioxide slowed elongation of the first internode and inhibited ethylene action. Elongation of the first internode due to deep-seeding and ethylene treatment showed high heritabilities, suggesting a genetic basis underlying those traits.
