aim of this study was to develop an in situ,
non-destructive method for observation and monitoring of the
underground developmental stages of the root parasite Orobanche
The parasitic weed Orobanche
causes severe damage to vegetables and field crops. Most of the damage
occurs during the underground, unobservable parasitism stage. Sunflower
cv. Adi) plants were planted in a soil that was artificially inoculated
Clear Plexiglas minirhizotron observation tubes were inserted into the
soil. Seed germination, early stage of penetration, and formation of
tubercles and spikes were observed non-destructively and were monitored
as video images throughout the growing season by means of a
minirhizotron TV camera. Use of this technology enabled monitoring the
complete individual parasite life cycle, from germination to
shoot emergence. In addition, the effect of the systemic herbicide imazapic on
the development of O.
was inspected and quantified. This novel methodology facilitates the
study of major aspects of the host-parasite interaction, parasitism
dynamics, parasite growth rate and the effect of chemical treatments
on the parasite.
