Abstract

An experiment was conducted at seed science and technology laboratory, agriculture Faculty, Unsyiah from Mei to Agustus 2003. The objectives of this research were to evaluate the effect of organic compound on improving of mangosteen seed vigor. The research was calcilated with non factorial, based on Complete Randomized Design with four replications. The treatments were control and organic compound of five levels, i.e. coconut oil, corn, banana, carrot, and tomato. Each extract concentration used was 15%. Variables such as growth potential, seedling growth rate, speed of germination, and uniformity of growth were measured. The results showed that all organic compound significantly increased growth potential, seedling growth rate, speed of germination, and uniformity of groth. The coconut milk treatment is the best to increase mangosteen seed vigor.

Abstract

Fungi mikoriza arbuskula (FMA) membentuk simbiosis mutualisme dengan banyak tanaman. Fungi ini berperan penting dalam ekosistem melalui kemampuannya meningkatkan keanekaragaman tanaman dan kualitas tanah. Survey dilakukan untuk mengetahui keanekaragaman FMA pada rizosfer beberapa varietas jagung dan kolonisasinya pada akar tanaman. Metode yang digunakan adalah isolasi langsung dan kultur trapping dengan sorgum sebagai tanaman inang. Hasil isolasi menunjukkan jumlah dan jenis spora FMA hasil kultur trapping lebih banyak daripada isolasi langsung. Jenis spora FMA yang dijumpai pada isolasi langsung adalah Glomus, Acaulospora dan Gigaspora sedangkan pada kutur trapping adalah Glomus, Acaulospora, Gigaspora, dan Scutellospora. Glomus merupakan spora FMA terbanyak yang dijumpai pada rizosfer jagung pada Inseptisol. Persentase kolonisasi akar tertinggi dijumpai pada akar jagung hibrida Bisi 2 yaitu 74,67%.
