1. KEDUDUKAN DAUN VERTIKAL/HORISONTAL)
2. BENTUK DAUN (JARUM, LEBAR)
NISBAH LUAS DAUN
NLD : HASIL BAGI LUAS DAUN DENGAN BERAT
KERING TOTAL TANAMAN
NLD : HASIL BAGI LAJU PERTUMBUHAN RELATIF
DENGAN HARGA SATUAN DAUN.
NLD = LPR ATAU NLD = LD
HSD BKT
NISBAH BERAT DAUN
 LUAS DAUN DITENTUKAN OLEH JUMLAH
BAHAN TANAMAN (KARBOHIDRAT) YANG
DIALOKASIKAN KE BAGIAN DAUN
 DAUN TUA BERBEDA DENGAN DAUN MUDA
 PEMBAGIAN/TRANSLOKASI KARBOHIDRAT KE
DAUN MENENTUKAN PERKEMBANGAN
TANAMAN DALAM SIKLUS HIDUPNYA.
 PEMBAGIAN KARBOHIDRAT SUATU FENOMENA
INVESTASI MODAL KE BAGIAN TANAMAN YANG
PRODUKTIF.
NISBAH BERAT DAUN
NBD = BERAT DAUN
BERAT DAUN TOTAL
NBD MENGIKUTI POLA PERTUMBUHAN SIGMOID
LUAS DAUN SPESIFIK
PROSES LAIN YANG MENENTUKAN LUAS DAUN
SELAIN PEMBAGIAN KARBOHIDRAT KE BAGIAN
DAUN YANG EFISIEN ADALAH PEMBENTUKAN
LUAS DAUN PER SATUAN KARBOHIDRAT YANG
TERSEDIA.
HAL INI DAPAT DIPELAJARI/DIKETAHUI
MELALUI SUATU INDEKS YANG DIKENAL
DENGAN LUAS DAUN SPESIFIK.
LUAS DAUN SPESIFIK (LDS) YAITU
HASIL BAGI LUAS DAUN DENGAN
BERAT DAUN
LUAS DAUN SPESIFIK (LDS) = LD
BD
HASIL PERKALIAN ANTARA LDS DAN NBD
MENGHASILKAN NLD
LUAS DAUN SPESIFIK
KETEBALAN DAUN
KANDUNGAN CHLOROFIL
