Gibberellins and Light Regulated Petiole Growth in Thlaspi arvense L.
Petiole growth in Thlaspi arvense L. was stimulated when a basic 8 hour photoperiod (4.20 milliwatts per square centimeter) was extended with low intensity light (0.16 milliwatt per square centimeter) from incandescent lamps. The day length extension was effective only when the light contained high proportions of far red light. Exogenous gibberellin A(3) (GA(3)) could partially substitute for t...

متن کاملComparison of Biological Activities of Gibberellins and Gibberellin-Precursors Native to Thlaspi arvense L.
Field pennycress (Thlaspi arvense L.) is a winter annual weed with a cold requirement for stem elongation and flowering. The relative abilities of several native gibberellins (GAs) and GA-precursors to elicit stem growth were compared. Of the eight compounds tested, gibberellin A(1), (GA(1)), GA(9), and GA(20) caused stem growth in noninduced (no cold treatment) plants. No stem growth was obser...
متن کاملSelection and Characterization of a Gibberellin-Deficient Mutant of Thlaspi arvense L.
Field pennycress (Thlaspi arvense L.) is a winter annual weed with a cold requirement for reproductive development. Previous work in this laboratory has demonstrated that the bolting aspect (rapid stem growth) of reproductive development is mediated by gibberellins (GA). The present paper describes the selection and characterization of a mutant lacking the capacity for thermoinduced stem growth...
متن کاملLocalization of the Site of Perception of Thermoinductive Temperatures in Thlaspi arvense L.
This paper describes attempts to localize the site of perception of low temperatures (0-10 degrees C) during thermoinduction in Thlaspi arvense L. Reproductive development (stem elongation and flower formation) was observed when shoots were cooled to 4 degrees C for 4 weeks and then returned to 21 degrees C while maintaining the roots constant 21 degrees C. However, chilling the roots was ineff...
