  • 3. AGR 3506 : PRINSIP SAINS TANAMAN 1. Morfologi dan Pengkelasan MORFOLOGI TANAMAN Struktur & morfologi • 2 bahagian asas :  akar : bahagian di bawah tanah  pucuk : bahagian di atas tanah • morfologi digunakan utk pencaman tumbuhan :  batang  daun  akar  bunga 01  biji benih
  • 4. AGR 3506 : PRINSIP SAINS TANAMAN 1. Morfologi dan Pengkelasan Morfologi Daun • 5 jenis daun :  foliage leaves  budscales  floral bracts  sepal  cotyledon • fungsi daun :  sintesis makanan melalui fotosintesis  perlindungan (kudup, tunas)  penyimpanan (endosperma dlm kotiledon 02

  • 6. AGR 3506 : PRINSIP SAINS TANAMAN 1. Morfologi dan Pengkelasan Morfologi Daun • ubahsuaian daun :  glan ( glands for secretion)  duri (spines or thorns (protection)  storage tissues (bulb - onion)  thickened leaf surface (reduce moisture loss)  kutikel nipis (thin cuticle) (submerge conditions)  sulur paut ( tendrils - support, climbing) 04
