Cholidia, Dinia (2017) Model Laju Pertumbuhan Perkecambahan Tanaman Jagung (Zea mays L.) Pada Variasi Massa Benih Jagung. Sarjana thesis, Universitas Brawijaya.
Abstract
Laju pertumbuhan tanaman jagung dipengaruhi oleh penentuan varietas unggul yang dilakukan dengan penentuan mutu benih. Patokan mutu benih yaitu bentuk dan massa benih, daya tumbuh, vigor serta kemurnian benih. Massa benih sangat berpengaruh dalam perkecambahan karena didalam benih terdapat cadangan makanan (endosperm) yang berfungsi untuk menyuplai makanan pada proses perkecambahan. Pertumbuhan perkecambahan benih dapat di prediksi dengan menggunakan model matematis pertumbuhan kurva tipe S. Model ini mengasumsikan bahwa pada masa tertentu jumlah populasi akan mendekati titik kesetimbangan (equilibrium). Penelitian ini menggunakan perlakuan faktor tunggal (massa benih) dengan tiga perlakuan massa benih besar 0,39 – 0,293 g, massa benih sedang 0,254-0,292 g dan massa benih kecil 0,155 – 0,253 g setiap perlakuan diulang tiga kali. Pengamatan dan Analisis Data dilakukan meliputi parameterdaya perkecambahan, tinggi tanaman,diameter batang, massa basah dan kering tanaman. Parameter daya perkecambahan yang diperoleh dianalisis dengan menggunakan tiga model matematis perkecambahan yaitu model Gompertz, Logistic dan General Logistic. Hasil dari penelitian ini menyatakan bahwa laju pertumbuhan perkecambahan jagung meningkat dengan semakin besarnya massa benih biji. Sedangakan untuk pemodelan sendiri dari ketiga perlakuan tersebut yang sesuai dengan data yang dihasilkan selama proses pengamatan adalah model Gompertz memberikan hasil lebih tinggi dibandingkan model Logistik dan model General Logistic.
English Abstract
The rate of growth of maize plants is influenced by the determination of superior varieties conducted by the determination of seed quality. Seed quality is the shape and mass of seed, growing power, vigor and purity of seed. The seed mass is very influential in germination because in the seed there is food reserves (endosperm) which serves to supply food in the germination process. Growth of seed germination can be predicted by using mathematical model of growth of type S. curve. This model assumes that at certain times the population number will be close to the equilibrium point. This research used single factor treatment (seed mass) with three large seed mass treatment 0,39 - 0,293 g, medium seed mass 0,254-0,292 g and small seed mass 0,155 - 0,253 g each treatment repeated three times. Observation and Data Analysis conducted include germination power parameters, plant height, stem diameter, wet mass and dry plants. The germination power parameters obtained were analyzed using three germination mathematical models that were Gompertz, Logistic and General Logistic models. The result of this study indicate that the growth rate of maize germination increases with the greater mass of seeds. While for the self-modelling of the three treatments that match the data generated during the observation process is the Gompertz model gives higher result than the Logistic model and general Logistic model.
