Abstract

The objective of this research was to know whether citric acid was able to decrease effect of aluminum on the seedling growth of soybean (Glycine max L.) varietas anjasmoro.   The experiment was conducted in Plant Physiology Laboratory, Department of Biology, Faculty of Mathematic and Natural Science, Lampung University on January 2016 in 2x3 factorial designs. Factor A was aluminum with 2 levels : 0 mM and 5 mM.  Factor B was citric acid with 3 levels : 0 mM, 5 mM and 10 mM.  Variables in this research were fress weight, dry weight, relative water content and total chlorophyll content.   Analysis of variance was conducted  at  5% significant  level.    If  interaction  was  not  significant,  main  effect  was determined with lsd test at 5% significant  level. If interaction was significant simple effect was determined with F test at 5% significant level.  The result showed that the citric acid decreased fress weight, dry weight, relative water content and no effect on total chlorophyll content while aluminum did not affect all variables and no interaction between citric acid and aluminum on all variables. It is concluded that citric acid was not able to inprove seedling growth of soybean varietas anjasmoro with aluminum or no aluminum. Keyword : Citric acid, Aluminum,  Soybean, Frees weight , dry weight

Abstract

Phalaenopsis amabilis cultivated have many constraints such as the appearance of fusarium wilt disease caused by Fusarium oxysporum. Plantlet P.amabilis which resistant to F. Oxysporum was selected in the solid Vacin and Went (VW) medium was added with salicylic acid at concentrations of 65 ppm, 75 ppm, and 85 ppm, compared with controls (0 ppm). The goals of the research were to study and determine of: 1) The SA concentration of planlet P. amabilis selection tolerant; 2) The proper concentration of AS during in vitro selection for suppressing the Fo. The research was carried out in December 2015 to February 2016 in the Botany Laboratory (in vitro research room), Departement of Biology, Faculty of MIPA, Lampung University. The result showed that: 1) The SA tolerant concentration for plantlet selection with P. amabilis was between 65 ppm - 85 ppm. 2) The 85 ppm of SA was effective for suppressing the Fo compared to 65 ppm and 75 ppm. Keywords: Phalaenopsis amabilis, salicylic acid, Fusarium oxysporum, In vitro, Resistance.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah ekstrak daun jarak pagar dapat menghambat pertumbuhan jagung hibrida varietas bisi 18, serta untuk mengetahui variabel mana yang lebih sensitif terhadap pengaruh ekstrak air daun jarak pagar. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 taraf konsentrasi ekstrak air daun jarak pagar yaitu 0% b/v (kontrol) 5% b/v  10% b/v 15% b/v 20% b/v dengan 5 kali ulangan. Variabel yang diamati dalam percobaan ini adalah panjang tunas, berat segar dan berat kering kecambah, kadar air relatif,  dan kandungan klorofil a, b, dan total. Data hasil penelitian ini dianalisis ragam pada taraf 5% jika hasilnya berpengaruh maka di lanjutkan dengan uji BNT pada taraf nyata 5%. Hasil penelitian menunjukan bahwa ekstak daun jarak pagar konsentrasi 20% menurunkan panjang tunas dan berat kering secara signifikan kecambah jagung hibrida varietas bisi 18. Dari hasil penelitian ini dapat disimpulkan bahwa ekstrak daun jarak pagar mempengaruhi panjang tunas dan berat kering, tetapi tidak mempengaruhi berat segar kecambah, kadar air relatif, rasio tunas akar dan klorofil jagung hibrida varietas bisi 18.

Abstract

Tujuan dari penelitian ini adalah membuktikan bahwa pada fase awal pertumbuhan vegetatif padi gogo varietas Inpago 8 tahan terhadap alelopati dari ekstrak daun kering babandotan (Ageratum conyzoides L.). Penelitian ini dilakukan pada bulan November – Desember 2018 di Laboratorium Botani Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Lampung. Penelitian ini menggunakan metode RAL (Rancangan Acak Lengkap) dengan ekstrak daun kering babandotan sebagai faktor utamanyayang terdiri atas 5 taraf konsentrasi yaitu 0% b/v, 2,5% b/v, 5% b/v, 7,5% b/v, dan 10% b/v dan terdiri dari 5 kali ulangan. Parameter yang diukur dalam penelitian ini adalah daya kecambah, panjang tunas, berat segar, berat kering,kadar air relatif, dan kandungan klorofil a,b serta total kecambah. Homogenitas ragam ditentukan dengan uji Levene pada taraf nyata 5%. Analisis ragam dan uji BNJ dilakukan pada taraf nyata 5 %. Hasil penelitian ini menunjukkan bahwa ekstrak daun kering babandotan tidak bersifat alelopati terhadap perkecambahan benih padi gogo varietas Inpago 8. Pada konsentrasi 7,5% b/v menstimulasi pertumbuhan kecambah padi gogo Inpago 8 yang ditunjukkan oleh peningkatan panjang tunas dan berat segar tunas.
