* The FTSE 100 futures contract was up 0.9 percent by 0637 GMT.
* Shares in stocks with significant business ties to Scotland, such as Royal Bank of Scotland, Lloyds Banking Group, energy firm SSE and engineering firm Weir were seen opening up 2 to 3 percent, traders said.
* Sterling, already pushed up on Thursday by expectations that Alex Salmond's nationalists would fall short of the majority needed to break up their union with England, struggled to add to early gains but was still up about a third of a percent on the day at $1.6447.
* The UK blue chip index had closed up 38.39 points, or 0.6 percent, at 6,819.29 points on Thursday in anticipation of the vote.
* A Thomson Reuters basket of 12 stocks listed on Britain's FTSE 350 index, headquartered in Scotland, has slowly risen over the last two weeks. (link.reuters.com/wej72w)
* Antonin Jullier, head of equity trading strategy at Citi, said: "There is a relief rally and the pound is rising already, which is logical. If the pound rebounds too much on the back of short covering then it could brake the FTSE's rise."
"Volatility is also likely to come down today...(But) given the recent focus on the vote and the potential for Scotland to gain more control even in a "No" vote, the market reaction may turn out to be a lot more muted than headlines would have suggested."
* Trading could be choppy, however, in morning trade due to "triple-witching" - when the contracts for stock index futures, stock index options, and stock options expire on the same day.
