Pengaruh pemberian hormon tumbuh dan diameter stek terhadap pertumbuhan stek jeruk nipis tanpa biji (citrus aurantifolis s)
Get PDFThis study aims to determine the effect of growth hormone and diameter cuttings seedless lime (Citrus aurantifolis S). This research conducted experiments using a randomized block design (RAK) are arranged in a factorial of two factors. The first factor is the growth hormone (H) and the second factor is the cutting diameter (D). The results showed that growth of hormone Rootone-F with diameter cuttings 0.7 cm and interactions gives the best effect on the growth of seedless lemon cuttings.

PENGENALAN ENZIM AMILASE (ALPHA-AMYLASE) DAN REAKSI ENZIMATISNYA MENGHIDROLISIS AMILOSA PATI MENJADI GLUKOSA
Get PDFAmilase (Alpha-amylase) adalah enzim yang mengkatalisis hidrolisis dari alpha-1, 4-
glikosidik amilosa pati menghasilkan glukosa. Jumlah glukosa yang dihasilkan selama
reaksi enzimatis diukur dengan menggunakan pereaksi dinitrosalycilic acid (DNS) pada
panjang gelombang 550 nm. Semakin tinggi nilai absorbansi yang dihasilkan, semakin
banyak pula gula pereduksi (glukosa) yang terkandung dalam sampel.Larutan DNS
yang awalnya berwarna kuning akan bereaksi dengan gula reduksi sehingga
menimbulkan warna jingga kemerahan. Kurva standar glukosa nilai persamaan y=
0,0034x + 0,1818, R²=0,9875yang berarti data tersebut termasuk teliti.Berdasarkan data
absorbansi glukosa tereduksi yang dihasilkan dari hidrolisis pati oleh enzim alphaamilaseterlihat bahwa semakin lama waktu kinerja enzim amilase, semakin menurun
nilai absorbansinya yang berarti kadar glukosanya semakin menurun (fluktuatif),
kemungkinan kenaikan suhu menyebabkan terjadinya proses denaturasi, bagian sisi
aktif enzim akan terganggu dan menyebabkan konsentrasi enzim menjadi berkurang
sehingga kecepatan reaksinya pun akan menurun. Pengujian pati sisa; persamaan untuk
kurva standar pati, y= 8.6x+0.021, nilai R2=0,9908, semua larutan sampel berwana
kuning dan nilai absorbansinya sangat rendah (hampir mendekati nol), hal ini berarti
kemungkinan hampir semua pati yang terkandung dalam larutan telah terhidrolisis oleh
enzim alpha amilase menjadi glukosa. Apabila terdapat amilosa pati dalam larutan akan
berpengaruh dalam pembentukan intentitas warna warna biru-hitam, hal ini disebabkan
oleh adanya molekul iodium (Ion-ion triiodida) yang terikat dalam kumparan helix
amilosa pati.

EFFECT OF SEEDLING AGE ON GROWTH & YIELD OF BINA DHAN 6
Get PDFAn experiment was conducted at Rangpur, Bangladesh during November 2015 to July 2016 to study the effect of seedling ages on the growth & yield of BINA dhan 6. Seedlings of different ages, viz 25, 35, 45, 55 & 65 days old were transplanted on the same day. Result revealed that plant height, number of leaves hill-1, total dry matter (TDM) hill-1, leaf area index (LAI), number of total tillers, number fertile tillers hill-1, number of grains panicle-1, 1000 grain weight, grain & straw yield was affected significantly due to different ages of seedlings. The result also showed that number of tillers hill-1, number of leaves hill-1, & leaf area index increased for all seedling ages up to 75 days after transplanting (DAT) and decreased gradually thereafter. The highest number of tillers hill-1, leaves hill-1 and leaf area index, the highest amount of stem, leaf, root and total dry matter and CGR were obtained from 35days old seedlings at all sampling dates. The highest number of effective tillers hill-1, panicle length, number of grains panicle-1, grain yield (6.96 t ha-1) and straw yield (7.75 t ha-1) were also achieved by 35 days old seedlings at harvest. Thirty-five days old seedlings were found to be superior to other ages of seedlings in term of growth and grain yield
