“…SHARMA (1956) has recently stressed the 'importance of detailed karyotypic study to find out structural changes in the chromosomes, in vegetatively propagated plants where gametic unbalanced conditions are not eliminated. SHARMA and SHARMA (1959) All of them are vegetatively propagated. SHARMA (1956) has emphasised that such altered nuclei play a distinct role in the origin of new types through the formation of daughter shoots.…”

“…It is quite established that polyploidy is often asso ciated with reduction in chromosome length as recorded in a large number of species (vide Stebbins 1950, Sharma andSharma 1959). This reduction has been attributed to several reasons including compact spiralization.…”
“…Singh and Roy (1970) also supported the view that x=8 should be regarded as the primary base number and the other base numbers like x=4, 6, 7 should be considered as derived. Further, it was observed that there is relationship between increase in chromosome number and reduction in chromosome size (Dowrick 1952, Darlington 1955, Sharma and Sharma 1959, Singh and Roy 1970.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
