Growth performance of native endangered species c. tabularis and a. polystachya in Chittagong University Campus.

1. Welcome

2. Growth Performance of Native Endangered Species C. tabularis and
A. polystachya seedlings at Chittagong University Campus

3. 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

4. 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.

5. 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.

8. Findings

11. Individual value plot of collar diameter vs fertilizer in three altitude
A. polystachya

14. Test of Significant
Comparison between Factors Significant test result
Height increment of c. tabularis
comparison among sites
Significantly different
Height increment of A. Polystachya
comparison among sites
Significantly different
Collar diameter increment of c.
tabularis comparison among sites
No Significant different
Collar diameter increment of A.
Polystachya comparison among sites
No Significant different

15. 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.
