Abstract
Kedelai (Glycine max L.) mempunyai arti penting untuk
memenuhi kebutuhan pangan dalam rangka perbaikan gizi
masyarakat, karena kandungan nutrisinya yang banyak dan
merupakan sumber protein nabati yang ekonomis. Kendala dalam
produksi kedelai adalah faktor lingkungan, salah satunya adalah
curah hujan yang dapat mengakibatkan genangan (waterlogging).
Tujuan dari penelitian ini adalah mengetahui respon karakter
fisiologis kedelai varietas Grobogan dan toleransinya terhadap
cekaman genangan.
Penelitian cekaman genangan dilakukan pada stadia
vegetatif dengan taraf genangan 100%, 150%, 200% dan kontrol
sebagai pembanding. Berdasarkan data didapatkan hasil bahwa
tinggi tanaman tertinggi terdapat pada konsentrasi genangan
150% (G2) dan terendah pada kontrol (G0), namun secara
keseluruhan tidak berbeda nyata. Sedangkan luas daun, panjang
akar, nitrogen daun, nodul akar, kadar klorofil, berat basah dan
berat kering mengalami penuruan seiring dengan bertambahnya
konsentrasi genangan. Etilen mengalami peningkatan pada
konsentrasi genangan 200% (G3) yaitu mencapai 14,878 ppm.
Rasio stomata yang membuka semakin sedikit seiring dengan
pertambahan perlakuan taraf genangan.

Soybean (Glycine max L.) has important role to fulfilling
food necessity in order to improve people nutrition, because it has
extra nutrition and economic vegetable protein source. Obstacle in
the production of soybean are environmental factors, one of it is
rainfall that can lead to waterlogging. The purpose of this research
was to determine tolerance and response of the physiological
characteristics of soybean (Glycine max L.) Grobogan variety in
watelogging stress.
The research of waterlogging stress is conducted in
vegetative stadia with the concentration of waterlogging is 100%,
150%, 200% and control as comparison. Based on the data, the
highest plant is the concentration of waterlogging 150% (G2)
besides the shortest plant is the control (G0) but overall the plant
height was not significantly different. While the leaf’s wide, root
length, nitrogen in leaf, root nodules, chlorophyll content, fresh
weight and dry weight, are decline as the waterlogging
concentration increased. Ethylene increased significally in the
concentration of 200% (G3) it reach 14,878 ppm. The next result
showed that the ratio of stomatal opening decreases with the
increase of the level of waterlogging treatment.
