Phototropism in Hypocotyls of Radish [PDF]
Plant Physiology, 1986 When etiolated radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls were subjected to a continuous unilateral illumination with white fluorescent light (0.1 watt per square meter), the growth rate at the lighted side was strongly inhibited for the first 2 hours, while that at the shaded side showed no change.

Comparison of different methods of proline application to alleviate the effect of nickel stress on germination and seedling growth of Cucumis melo var. Flexousus [PDF]
علوم و فناوری بذر ایران, 2022 Nickel is an essential microelement, but the increased concentration it in the medium disrupts the germination and growth of plants. In the present study, the effect of pretreatment and exogenous proline in the seedling growth of Cucumis melo under ...

The combined effects of light intensity, temperature, and water potential on wall deposition in regulating hypocotyl elongation of Brassica rapa [PDF]
PeerJ, 2020 Hypocotyl elongation is a critical sign of seed germination and seedling growth, and it is regulated by multi-environmental factors. Light, temperature, and water potential are the major environmental stimuli, and their regulatory mechanism on hypocotyl ...

Plants, 2022 Unlike typical negative gravitropic curvature, young hypocotyls of Brassica rapa and other dicots exhibit positive gravitropism. This positive curvature occurs at the base of the hypocotyl and is followed by the typical negative gravity-induced curvature.

Gibberellin Response in Lettuce Hypocotyl Sections [PDF]
Plant Physiology, 1975 Excised lettuce (Lactuca sativa L.) hypocotyl sections retain the ability to elongate in response to gibberellic acid (GA(3)) addition. In 48 hr at 30 C a GA(3)-treated segment more than doubles while a control segment elongates less than 50%. Auxin has no detectable effect on this system.
