Tissue structures comparison of leaf and root in musa spp using histology technique / Muhammad Amyriul Naufa Mohd Yusoff

There are three type of Musa spp diseases that had been study which is Musa
acuminate (AA Group) "Pisang Emas" that was infected by the Panama diseases,
Musa acuminate (AAA Group) "Pisang Abu" was infected by Moko diseases and
Musa acuminate (AAA Group) "Pisang Jelai Berangan" was infected by Black
leaf streak diseases. In order to view and study these changes, histological
technique were be applied. Hence, during this study, xylem and phloem structure
for infected "Pisang Abu" and "Pisang Emas" had been study by using histology
technique with dino eye software. Base on the observation for" Pisang Emas" the
result showed the structure for infected xylem· and phloem had decrease in size of
opening where it tend to shrink from their normal size. The diameter for healthy
"Pisang Emas" was the highest than the infected one which was for healthy
0.34±0.01 mm meanwhile the was infected 0.32±0.02 mm. Next was the infected
"Pisang Abu" where the structure of xylem and phloem tend to be. blocked by
degeneration of xylem and phloem wall structure the xylem and phloem structure
were be destroyed because the bacterium feed on these tissue structure. The
diameter for healthy xylem and phloem "Pisang Abu" was the highest than the
infected one which is for healthy 0.35±0.03 mm but the infected xylem and
phloem was 0.28±0.02 mm. Meanwhile, for the "Pisang Jelai Berangan" the
measurement for xylem and phloem structure was not taken because Black leaf
streak diseases did not affect this structure. The Black leaf streak diseases only
affect stomata count on the structure leaf. The total stomata for "Pisang Jelai
Berangan" were higher than infected leaves with 640,119 on upper epidermis and
8,470,295 for lower epidermis. While infected leaves were 184,271 on upper
epidermis and 5,047,813 for lower epidermis with area for leaf surface 3262.5
