Seedlings of Bambusa tidda Roxb. and Dendrocalamus strict us Nees were grown in the
nursery under four different light conditions, viz. sunlight, partial sunlight, shade, and
6 hours photoperiod up to nine months of age. Almost all the seedlings were dead (80 to
90%) under shade and 6-hr grolux electric light photoperiod conditions after 200 -270
days. Survival was highest (80-95%) under both sunlight and partial sunlight condition.
The seedlings were comparatively healthy, green and tall under partial sunlight. Under
these two light conditions seedings started clump formation within three months of age.
The clump formation was delayed and a very few bamboo seedlings formed weak clumps
under shade and 6 hours photoperiod conditons.
