Developmental Aspects of Leaf Blade Hyponasty
Botanical Gazette, 1977Nastic curvatures can be induced by indole-3-acetic acid (IAA) or transport inhibitors in the leaves of 4-day-old seedlings of Phaseolus vulgaris var. Pinto, but not in leaves of 10-day-old seedlings in which the capacity for differential growth is reduced.

Grass leaf blade development: Modification of the source
Canadian Journal of Plant Science, 1999Developing leaf blades of tall fescue (Festuca arundinacea Schreb.) were subjected to three treatments that modify their source capacity: (1) emerged tips cut daily, (2) grown in darkness or (3) grown at the CO2 compensation point. Treated and control leaves developed similarly but treated leaves senesced rapidly at the leaf tip.

Middle-earth’s pervasive atmosphere of realism breathes life into his fiction. This subcreated world stretches its unstressed believability beyond animation to sentience and beyond sentience to awareness. Middle-earth, like the creature in the old Frankenstein movies, is “alive!”—and much less melodramatic about it than mad scientists.

Leaf blade movement of Drosera and auxin distribution
Naturwissenschaften, 1985The leaf of the South African sundew Drosera capensis folds over its prey to form an "outer s tomach" (Fig. 1). The movement is induced not only by the organic material of the prey but also by a local application of NH4H2PO4 as a signal. The speed and intensity of the bending is enhanced by external auxin treatment.

Epidermal Patterns of the Leaf Blade in Selected Andropogoneae
2023Epidermal patterns of the widest portion of the leaf blade of selected members of the Andropogoneae were studied. These included 23 genera and 71 species, some of which were duplicates, making a total of 83 entries. The specimens were collected by Dr. H. C.

Leaflet initiation and blade expansion are separable in compound leaf development
The Plant Journal, 2020SUMMARYCompound leaves are composed of multiple separate blade units termed leaflets. In tomato (Solanum lycopersicum) compound leaves, auxin promotes both leaflet initiation and blade expansion. However, it is unclear how these two developmental processes interact.

Auxin-Cytokinin Effects in Leaf Blade Hyponasty
Botanical Gazette, 1978The cytokinins K, BA, and FA reduce auxin-mediated hyponasty of the primary leaf blade of Phaseolus vulgaris L. var. Pinto. The inhibition of auxin-mediated hyponasty by cytokinins differs from that produced by auxin-transport inhibitors in time course, amount of inhibition, and effective site of application.

The Role of Meristematic Activities in the Formation of Leaf Blades
Journal of Plant Research, 2000(L.) Heynh. Leaf primordia also have their own meristematic regions and meristematic activity is maintained in part of the leaf blade, in some case, even after maturation. Transgenic plants have been generated that have proved to be useful tools in the analysis of the behavior of meristematic regions in leaf blades of A. thaliana. This review, based on
