Radial hydraulic conductivity along developing onion roots.

Although most studies have shown that water uptake varies along the length of a developing root, there is no consistent correlation of this pattern with root anatomy. In the present study, water movement into three zones of onion roots was measured by a series of mini-potometers. Uptake was least in the youngest zone (mean hydraulic conductivity, Lpr = 1.5 x 10(-7) +/- 0.34 x 10(-7) m MPa-1 s-1...

Effect of Irrigation Frequency and Fungicide Spray on Yield and Disease Infection of Onion

A two-year field experiment was conducted at Regional Agricultural Research Station, Jessore during the rabi seasons of 2002—2003 and 2003-2004 to find out the level of disease incidence under different levels of irrigation and fungicide spray on the bulb yield of onion. Four irrigation levels: no irrigation (I1), irrigation at 10 days interval (I2), 20 days interval (I3), and 30 days interval ...

Infection of Narcissus Roots by Aphelenchoides subtenuis.

The widespread destruction of commercially grown bulbs of Narcissus tazetta papyraceus (Paper White) has been reported in Israel. This phenomenon is usually characterized by a premature yellowing of the foliage, accompanied by root rot and dark, sunken basal plates. This study confirmed thatAphelenchoides subtenuis is the main cause of the basal plate disease of Narcissus. In contrast to other ...

Evidence for symplastic involvement in the radial movement of calcium in onion roots.

The pathway of Ca(2+) movement from the soil solution into the stele of the root is not known with certainty despite a considerable body of literature on the subject. Does this ion cross an intact, mature exodermis and endodermis? If so, is its movement through these layers primarily apoplastic or symplastic? These questions were addressed using onion (Allium cepa) adventitious roots lacking la...

Suppression of Mitosis and Macromolecule Synthesis in Onion Roots by Heavy Water

Exposure of microorganisms to high concentrations of D20 slows or stops growth, but the inhibition is often overcome after a time; in many instances, serial subculture leads to successful adaptation the many component processes of population growth, seems generally to be the most sensitive process. Shifts in the patterns of nucleic acid synthesis are sometimes seen (Flaumenhaft, Conrad, and Kat...
