Radicle of Echinocactus platyacanthus (Cactaceae)

Plant and Soil, 1994
Radicle of mature Echinocactus platyacanthus embryo is approximately 320 µm long and represents less then 1/7 of the embryonal axis length. The radicle-hypocotyl boundary can be distinguished according to the striking difference in the size and shape of cells in protoderm and procambium, as well as discontinuity and different number of the cell files ...

Probes for Detection of Free Radicles

2020
Reactive species are reactive molecules, having one or two lone pairs that are naturally generated in biological environment via endogenous and exogenous method. These are non-avoidable by-product, highly reactive which are mainly produced by the Electron Transport Chain (ETC) of mitochondria by aerobic respiration.

Natica as a Radicle

The American Naturalist, 1930
NATICA or the naticoici type holds a unique place in the ontogeny and phylogeny of the coiled Gastropoda. Its position in the history of the race has been admirably pointed out by Grabau1 in his " Studies of Gastropocla," and in his treatise on the "Phylogeny of Fusus and Its Allies. "9 There would be little cause at this time to take up the discussion

'Radicle' biochemistry: the biology of root-specific metabolism

Trends in Plant Science, 1999
The roots of higher plants are a fascinating and largely unexplored biological frontier. One of their features is the ability to synthesize a remarkable diversity of secondary metabolites, and to adjust their metabolic activities in response to biotic and abiotic stress.

Simulation of Cotton Radicle Elongation During Emergence

Transactions of the ASAE, 1977
ABSTRACT AN empirical computer simulation model for pre-dicting cotton radicle elongation under either constant or fluctuating conditions of the soil physical environment was developed from a set of experimental constant environment radicle growth data—radicle response for four levels each of temperature, moisture, and impedance.

Gavitropism of Pine Radicles in the Dark

New Forests, 2006
Although gravitropism of maize (Zea mays L.) roots is dependent on light, it is not known if light affects the gravitropism of pine radicles. Therefore, seeds of slash pine (Pinus elliottii Englm.) and loblolly pine (Pinus taeda L.) were germinated under constant light or constant darkness.

The Analogy between Radicles and Elements

Nature, 1915
THE remarkable chemical analogy of the ammonium radicle and the alkali metals may be explained with the help of Bohr's theory of atomic structure. According to Bohr, the atom of nitrogen consists of a nucleus with a positive charge of 7e, surrounded by two rings of electrons, the inner containing 4, the outer 3 electrons.

Biodegradation of Oxalic Acid from Spinach Using Cereal Radicles

Journal of Agricultural and Food Chemistry, 2005
A high level of oxalate intake constitutes a health risk for infants and metabolically disposed adults. Spinach, acclaimed for its many health benefits, is among the vegetables richest in oxalate. Blanching reduces oxalate unsatisfactorily and unspecifically.

Warm and freeze-fracture of cotton seed radicles

Proceedings, annual meeting, Electron Microscopy Society of America, 1987
In cotton seeds the radicle has 12% moisture content which makes it possible to prepare freeze-fracture replicas without fixation or cryoprotection. For this study we have examined replicas of unfixed radicle tissue fractured at room temperature to obtain data on organelle and membrane structure.Excised radicles from seeds of cotton (Gossyplum hirsutum

Growth Movements of the Radicle of Striga

Nature, 1960
THE directional growth of the radical (haustorium) of the root parasite Striga asiatica (= S. lutea) is normally controlled by a chemotropic factor diffusing from the host plant root1. The parasite seeds may be germinated by treatment with a solution in which the host roots (Sorghum vulgare, etc.) have been growing. In this case the radicle undergoes a
