Acclimatization of micropropagated Kappaphycus alvarezii (Doty) Doty ex Silva (Rhodophyta, Solieriaceae) in outdoor nursery system

The introduced alga Kappaphycus alvarezii (Doty ex P.C. Silva, 1996) in abandoned cultivation sites in Bocas del Toro, Panama

The red alga Kappaphycus alvarezii (Doty ex P.C. Silva, 1996) has been intentionally introduced throughout the tropics for mariculture. In some cases, the alga has spread outside cultivation sites and impacts native biota. We conducted surveys of two sites in Bocas del Toro, Panama, where non-native K. alvarezii was previously cultivated to determine whether it is established and began to exami...

Effect of Kappaphycus alvarezii (Doty) Doty ex silva. extract on grain quality, yield and some yield components of wheat (Triticum aestivum L.)

A pot experiment was conducted in rabi season 2004-05 to study the effect of Kappaphycus alvarezii extract applied as a foliar spray at 0.25%, 0.50% and 1.0% on wheat. Compared to control the yield of grain increased by 80.44% when, the plants were sprayed with 1.0% K. alvarezii extract. The nutritional quality of grain such as carbohydrate, protein and minerals also improved under the influenc...

Assessment of Four Molecular Markers as Potential DNA Barcodes for Red Algae Kappaphycus Doty and Eucheuma J. Agardh (Solieriaceae, Rhodophyta)

DNA barcoding has been a major advancement in the field of taxonomy, seeing much effort put into the barcoding of wide taxa of organisms, macro and microalgae included. The mitochondrial-encoded cox1 and plastid-encoded rbcL has been proposed as potential DNA barcodes for rhodophytes, but are yet to be tested on the commercially important carrageenophytes Kappaphycus and Eucheuma. This study ga...

Molecular identification of the exotic lineage of Kappaphycus alvarezii (Rhodophyta, Solieriaceae) cultivated in the tropical region of Brazil

Kappa carrageenan is an important phycocolloid extracted from the red seaweed Kappaphycus alvarezii. This species has been introduced into several regions, most recently in Brazil. The remote invasive potential of this seaweed in both south and southeast waters of Brazil (subtropical regions) has been established, but introduction in the northeastern tropical area is contested due to the absenc...
