Respon Fisiologis Dan Kadar Protein Total Daun Kedelai [Glycine max (L.) Merr.] Varietas Grobogan Terhadap Tingkat Naungan Yang Berbeda

---

ABSTRAK

Budidaya kedelai varietas Grobogan sebagai tanaman sela dalam sistem tanam
tumpang sari merupakan salah satu upaya untuk meningkatkan produksi kedelai,
namun, sebagai tanaman sela kedelai harus mampu beradaptasi terhadap kondisi
ternaungi. Penelitian bertujuan menganalisis respon fisiologis kedelai varietas
Grobogan terhadap tingkat naungan berbeda, meliputi perubahan kadar protein total
daun, kadar pigmen fotosintetik, indeks stomata dan lebar celah stomata serta
pertumbuhan vegetatif tanaman. Penelitian menggunakan Rancangan Acak Lengkap
(RAL) satu faktor berupa perbedaan tingkat naungan yaitu: tanpa naungan, naungan
50% dan naungan 70%. Data dianalisis menggunakan Analisys of Variance
(ANOVA) dan dilanjutkan dengan Duncan’s Multiple Range Test (DMRT) pada taraf
kepercayaan 95%. Hasil penelitian menunjukkan bahwa kedelai varietas Grobogan
merespon peningkatan taraf naungan dengan meningkatkan kadar protein total daun
dan pigmen fotosintetik serta menurunkan indeks stomata dan lebar celah stomata.
Tanaman ternaungi mengalami pertumbuhan vegetatif yang terhambat dilihat dari
penurunan jumlah daun, luas daun, tebal daun, tinggi batang, diameter batang,
panjang akar dan bobot tanaman. Kedelai varietas Grobogan mampu beradaptasi dan
bertahan hidup di bawah naungan 50% dan 70%.
Kata Kunci: pertumbuhan, pigmen fotosintetik, stomatav

ABSTRACT

Cultivation of soybean varieties Grobogan in intercropping system is one of the
efforts to increase soybean production, however, to grow properly as intercrops,
soybean must be able to adapt to shaded condition. The study aimed to analyze
physiological responses of soybean varieties Grobogan to different shade levels,
including changes in amount of leaf total protein content, photosynthetic pigments
content, index stomata and stomata gap width and vegetative growth. The research
was conducted using a Completely Randomized Design (CRD) one factor, that is
level shading with three treatments: no shading, 50% shade and 70% shade. Data
were analyzed by Analysis of Variance (ANOVA) and continued by Duncan's
Multiple Range Test (DMRT) at 95% confidence level. The results showed that
varieties Grobogan responded to increased shade by increasing leaf total protein
content and photosynthetic pigments content and decreasing index stomata and
stomatal gap width. Shaded plants showing stunted vegetative growth, seen by
decreased of leaf number, leaf area, leaf thickness, stem height, stem diameter, root
length and plant weight. Soybean varieties Grobogan is able to adapt and survive
under 50% and 70% shade.
Key words: growth, photosynthetic pigment, stomata
