dep. on motor trucks

Rate of Depreciation allowable as per income tax act on Motor truck(Lorries) which is used for commercial purpose acquired on or after 1-1-2009 but before 1-4-09 is 50%

The same was ammended w.e.f. 1-4-2010 that 1-4-09 is extended to 1-10-2009.

I want to know that whether any further ammendment  was came in regard of  extention of period of 1-10-09?
