Effecting/effects of thinning are:

A.Average tree size in the remaining crop increases with increasing weight of thinning
B.Delay in thinning is not compensated for in terms of girth increment by removing larger volume, unless this volume represents a greater proportion of the growing stock than did the earlier thinning
C.Both (a) & (b)
D.None of these

Coppice selection means:

A.When mature crop is removed by clear felling and regeneration is entirely by vegetative methods
B.When some selected shoots are selected for retention for future period
C.When crop is partly of coppicing and partly of seedling organ of different age clear
D.None of these
