Systematics and reproductive biology of Siparuna (Monimiaceae) in Panama.
(1983)
Some components of the essential oil from the leaves of Siparuna guianenis (Monimiaceae) were identified and determined in the steam-volatile extract. The major constituents are curzerenone (26%) and curzerenone types ...
Reproductive studies in the genus Callirhoe (Malvaceae)/
(1981)
Callirhoe involucrata (Torr.) Gray (Malvaceae) is protandrous; however, the temporal separation of the sexual phases is incomplete and the occurrence of a self pollination is possible. Unexpected results were obtained ...
Interactions between ecosystem carbon, nitrogen and water cycles under global change: Results from field and mesocosm experiments.
(2005)
N additions increased NEE by enhancing light interception, RUE, and extending growing seasons. Different N application methods (PF versus GF) caused differential seasonal dynamics of LAI, NEE and RUE due to their different ...
Characterization of clathrin adaptor proteins from cotyledons of developing pea (Pisum sativum L.).
(1998)
Procedures have been developed for the dissociation of coat proteins from clathrin-coated vesicles isolated from cotyledons of developing pea, Pisum sativum L. Based on molecular sizing chromatography, immunoreactivity, ...
Sperm cell characteristics in relation to its transport during fertilization in Plumbago zeylanica and Nicotiana tabacum.
(1999)
In Plumbago, the sperm cell that normally fertilizes the egg has a higher calculated charge (8.277 x 103 esu/cm 2) compared with the sperm cell that fuses with the central cell (6.120 x 103 esu/cm2). Microelectrophoresis ...
Nutrient and biomass allocation strategies for five grass species in an Oklahoma tallgrass prairie.
(1982)
Analysis of biomass, nitrogen, phosphorus, potassium and magnesium allocation patterns to various portions of the plant was undertaken to determine if differences exist between Andropogon gerardii, Schizachyrium scoparium, ...
