Evaluation of endophytic bacterial isolates on germination and haustorium initiation of Strigahermonthica (Del.
7) Table 5: Effects of carbohydrates on Strigahaustorium initiation in response to DMBQ: Haustorium (%) Carbohydrates concentrations g/100ml Glucose DMB Q Water 0.
The results showed that NH absolutely inhibited haustoria initiation in response to haustorium factor, while Mg caused a significant reduction in haustorial initiation compared to the control.
A negative relationship was observed between salt levels and germination percentage of Striga seeds during or after conditioning and haustorium.
Seven of the bacterial isolates screened had no effects on haustorium
It is known that Rhamphicarpa fistulosa connects its xylem system to the host plantthrough haustorium
Differential production of the enzyme catalase, which disproportionate H2O2 to H2O and molecular oxygen, by bacterial isolates would lead to differential production of DMBQ and hence differential reduction in haustorium
Once the tip of the radicle makes contact with the epidermis of a host, it swells and forms a haustorium
producing several one-cell-wide filaments that penetrate into cactus tissues through stomatal openings.
Germination, radicle elongation, haustorium
initiation, attachment and penetration are the earliest developmental stages of Striga.
Cotyledon The first leaf, consisting of haustorium
, middle part, and cotyledonary sheath.
The structure and development of the haustorium
in parasitic Scrophulariaceae.
These somewhat loosely defined haustoria are not strictly comparable with the chalazal and micropylar endosperm haustoria found in many Asteridae, such as Lamiaceae (Rudall & Clark, 1992), where distinct well-defined endosperm chambers are formed, often containing a few large coenocytic nuclei which may wander around the periphery of the haustorium
