No periodo de 1980 a 1982 foram conduzidos oito ensaios de competicao de cultivares de algodoeiro herbaceo, sendo tres ensaios nacionais e cinco regionais. Os ensaios nacionais foram instalados nos municipios de Teresina, Picos e Batalha, em um delineamento quadrado latino 7 x 7 e nos ensaios regionais adotou-se o delineamento de blocos ao acaso com oito repeticoes e conduzidos nos municipios de Teresina, Agua Branca, Oeiras e Eliseu Martins. As cultivares e linhagens testadas foram: BR-1, IAC-17, IAC-18, IAC-19, IAC-74/221, Su-0450/8909, PR-4139, PR-SM3, Allen 333/57, REBA-B/50, REBA-l/4139, MCU-5, CNPA-76/18, CNPA-76/6873, CNPA-76/6983,CNPA-77/149, CNPA-77/157, CNPA-77/150 e Minas Dona Beja. Constatou-se que as cultivares IAC-17, BR-1, PR-4139 e as linhagens CNPA-756/6873 e CNPA-77/150, foram as mais produtivas e que os municipios de Picos, Oeiras, Eliseu Martins possuem aptidao para o cultivo do algodoeiro herbaceo e que a linhagem CNPA-77/6983 e a cultivar BR-1, apresentaram as melhores caracteristicas tecnologicas de fibra. |

Manuka honey is a well-known natural material from New Zealand, considered to have properties beneficial for burn treatment. Gels created from polyvinyl alcohol (PVA) blended with natural polymers are potential burn-care dressings, combining biocompatibility with high fluid uptake. Controlled release of manuka honey from such materials is a possible strategy for improving burn healing. This work aimed to produce polyvinyl alcohol (PVA), PVA?sodium carboxymethylcellulose (PVA-CMC), PVA?gelatin (PVA-G), and PVA?starch (PVA-S) cryogels infused with honey and to characterize these materials physicochemically, morphologically, and thermally, followed by in vitro analysis of swelling capacity, degradation/weight loss, honey delivery kinetics, and possible activity against Staphylococcus aureus. The addition of honey to PVA led to many PVA crystals with defects, while PVA?starch?honey and PVA?sodium carboxymethylcellulose?honey (PVA-CMC-H) formed amorphous gels. PVA-CMC presented the highest swelling degree of all. PVA-CMC-H and PVA?gelatin?honey presented the highest swelling capacities of the honey-laden samples. Weight loss/degradation was significantly higher for samples containing honey. Layers submitted to more freeze?thawing cycles were less porous in SEM images. With the honey concentration used, samples did not inhibit S. aureus, but pure manuka honey was bactericidal and dilutions superior to 25% honey were bacteriostatic, indicating the need for higher concentrations to be more effective.
