Welcome

Growth Performance of Native Endangered Species C. tabularis and

A. polystachya seedlings at Chittagong University Campus

Why this Research?

Chukrasia tabularis and Aphanamixis polystachya both

are native Endangered Species.

C. tabularis is irregular seed producer.

Aphanamixis polystachya is a IUCN Red Listed Threaten

species

Objectives To investigate survival percentage of two endangered species C.

tabularis and A. polystachya seedlings.

To measure the growth performance of C. tabularis and A.

polystachya seedlings at three altitude of the hill at Chittagong

University Campus.

To investigate fertilizer effect on survivability and growth

performance of two endangered species C. tabularis and A.

polystachya.

How this Research carried out?

• Randomized block design were followed in this experiment, with three

replicates in three altitude each containing 3 plots.

• There were 28 trees in each plot spaced at 2m x 2m. Two boundary rows of

the same species were planted surrounding the experiment. Planting holes

were dug by spade.

Recommendation

The results depicts that growth performance of C. tabularis and A.

polystachya is better in lower altitude of the hill. Therefore, these two

species recommended for future planting at the lower altitude of the hill

at Chittagong University Campus.
