Pengenalan Hardware

Keyboard adalah salah satu bagian yang paling penting dari sebuah komputer yang digunakan untuk memasukkan perintah, teks, data numerik dan jenis-jenis data dengan menekan tombol pada keyboard. Ketidaktahuan pengaturan pada keyboard akan menyebabkan ketidaknyamanan dalam penggunaannya. Berikut ini adalah cara pengaturan keyboard yang kiranya dapat membantu anda.

Pengaruh Infestasi Ganda Meloidogyne incognita dan Cendawan Pengkoloni Nematoda Puru Akar pada Pertumbuhan Kedelai

Effects of Mixed Infestation of Meloidogyne incognita and Fungi Colonizing the Root-Gall Nematode on Soybean Growth. Laboratory and greenhouse experiments were carried out during April-October 1996 to investigate the response of three soybean varieties to the combined infestation of Meloidogyne incognita (Kofoid & White) Chitwood and three root-gall nematode colonizing fungi (MCF). The experiments were done in a factorial completely randomized design with three replications. Treatments in laboratory test were combination of three soybean varieties, i.e. Black soybean (V,), Wilis (Vd and Lokon (Vd, two initial population densities of M. incognita, i.e. 0 and 300/200 ml growth medium, and three MCF species, i.e. Paecilomyces sp., Gliocladium catenulatum, and Trichoderma viride. The greenhouse treatments were the combination of three soybean varieties (V,, V2, V3), three initial population densities of M. incognita (0, 1000, and 200014 1 growth medium), and three MCF species. Result of laboratory tests showed that the combination of M. incognita and three MCF species signifcantly reduced the damage level of M. incognita and root weight loss. Reduction of shoot weight loss occurred only in slightly resistant and susceptible varieties in combination with Paecilomyces sp. and G. catenulatum. Combination of T. viride and M. incognita on three soybean varieties showed synergistic interaction. Result of greenhouse tests showed that all of the MCF isolates significantly reduced the damage level and the final population of M. incognita. However, only Paecilomyces sp. could reduce the root weight loss, relative plant growth rate, and harvested seeds. These reducing eflects were achieved on Lokon variety only, that is susceptible to M. incognita. There was no synergistic interaction between M. incognita and T. viride in the greenhouse test, even though the root colonization frequency of Trichodenna sp. on the susceptible variety was rather high.
