Pollen hydration and self-incompatibility (SI) in Brassica have been studied by using a combination of in vivo video-microscopy and experiments with metabolic inhibitors. Experiments with cycloheximide confirm earlier observations that pollen hydration is regulated through protein synthesis. No protein or glycoprotein has positively been identified with(More)
The green plant regeneration ability from anthers of BR-7, a high yielding indica cultivar, Binnatoa (BA), a salt tolerant indica land race and IR-43 was tested in N6, M8, He2 and R2 media. The response was calculated on the basis of number of anthers producing green plants. The number of green plants per responding anther was also recorded. The response of(More)
Among the in vitro derived different explants such as cotyledonary leaf, hypocotyl, shoot tip and root of two local varieties, namely Singhnath and Kazla (BARI Begun-4) of eggplant (Solanum melongena L.) cotyledonary leaf was found to be the best for multiple shoot regeneration. High frequency direct organogenesis of shoots was achieved from cotyledonary(More)
Comparative study with fluorescence microscopy revealed that the pollen tubes of the self-pollinated rice variety BR-9 reached the ovary within 75 min after pollination. In P. coarctata it took 150 min. In the cross between P. coarctata and BR-9, pollen tubes reached the ovary in 165 min but seed setting was not observed. In the cross between BR-9 and P.(More)
Abstract Crosses were made between three varieties and seven accessions of white jute (Corchorus capsularis L.) in all possible combinations to establish 10 × 10 full diallel set. Variances for general combining ability (GCA) and specific combining ability (SCA) were significant or highly significant for all the characters indicating additive and(More)
The effect of nanoconfinement on the thermodynamics of free radical polymerization of sulfur is examined. We extend Tobolsky and Eisenberg's model of bulk sulfur polymerization to nanopores accounting for the confinement entropy of the chains and ring using scaling reported in literature. The model quantitatively captures literature data from Yannopoulos(More)
