Micrografting of Protea cynaroides

Role and significance of total phenols during rooting of Protea cynaroides L. cuttings

Phenolic compounds, which are known to regulate root formation, are found abundantly in difficult-toroot Protea cynaroides stem cuttings. In this study, analysis of total phenol content was carried out on blanched and unblanched cuttings to observe its fluctuation throughout the entire rooting period (120 days) and establish its relationship with root formation. Results showed that blanching si...

In Vitro Organogenesis of Protea cynaroides L. Shoot-Buds Cultured Under Red and Blue Light-Emitting Diodes

Flavonoid compounds of Lamyropsis cynaroides.

Lamyropsis (Charadze) Dittrich (Asteraceae) was erected to generic rank and clearly de"ned by Dittrich (1971). It is a member of tribe Cardueae Cass. subtribe Carduinae Dumort. and most closely related to the genera Cirsium and Ptilostemon. It currently comprises a total of 8 perennial species distributed from S Europe eastwards to Central Asia (Bremer, 1994). The morphological links of the gen...

Micrografting in Extensive Quantities

The exclusive use of very small grafts has moved from the experimental to the forefront. Dense packing of minigrafts of 1.5 mm or less in combination with one-or two-haired grafts offers the appearance of comparable density and undetectability, while using donor hair very efficiently. The use of smaller grafts in greater quantity offers many advantages normally unavailable with traditional larg...

New species of Anthostomella on fynbos, with a key to the genus in South Africa.

A study of saprobic fungi occurring on the fynbos of the Western Cape Province of South Africa yielded four unknown Anthostomella species. A. proteae from Protea nitida, A. cynaroides from P. cynaroides, A. leucospermi from Leucospermum oleifolium, and A. brabeji from Brabejum stellatifolium are described as new. New records for South Africa include A. conorum from Leucadendron sp., Protea magn...
