The Cost

Abstract Some plant species accumulate selenium in their tissues in quantities far above soil concentrations, and experiments demonstrate that selenium can serve as a defence against herbivores and pathogens. However, selenium may also cause oxidative stress and reduce growth in plants. We measured growth, selenium accumulation and herbivory in four varieties of the selenium accumulator Brassica juncea to investigate the cost of accumulation as well as its benefit in reducing herbivory. We measured selenium levels, plant size and flower number in four varieties of B. juncea watered with sodium selenate or treated as controls. We also conducted no-choice herbivory trials on leaves from both treatments with the specialist herbivore Pieris rapae. The selenate treatment slightly increased leaf number over the control, but tissue concentrations of selenium and flower number were negatively correlated in some varieties. In herbivory trials, leaves from the plants in the selenate treatment lost less leaf tissue, and the majority of larvae given leaves from selenate-treated plants ate very little leaf tissue at all. In the variety with the highest selenium accumulation, leaves from selenate-treated plants that showed reduced flower production also experienced less herbivory in feeding trials. The protective advantage of greater selenium accumulation may be offset by negative effects on reproduction, and the relatively low level of selenium accumulation in this species as compared to more extreme hyperaccumulators could reflect the minimum level necessary to enhance protection from herbivory.

Penelitian ini bertujuan untuk mempelajari variabilitas genetik, heritabilitas, dan menyeleksi penampilan genotipe karakter agronomi unggul pada 57 galur sawi untuk digunakan dalam bahan baku konsumsi dan industri. Penelitian ini dilaksanakan di Seed Bank and Nursery, Agrotechno Park Universitas Brawijaya, Desa Jatikerto, Kecamatan Kromengan, Kabupaten Malang pada bulan Desember 2018 – April 2019. Metode yang digunakan untuk penelitian ini adalah rancangan acak kelompok diperluas (augmented design). Perlakuan yang diberikan adalah 60 genotipe sawi yang terdiri dari 57 genotipe yang diuji dan 3 varietas sebagai cek. Genotipe yang diuji akan disebar kedalam 5 blok, sedangkan tiga varietas cek akan ditanam pada setiap blok, sehingga terdapat 72 satuan percobaan. Variabel pengamatan karakter agronomi terdiri dari 15 karakter kualitatif dan 24 karakter kuantitatif. Variabilitas yang luas terdapat pada karakter biji per polong, jumlah polong per tanaman, dan berat segar. Heritabilitas tinggi terdapat pada karakter panjang kotiledon, jumlah daun konsumsi, berat segar, umur panen benih, jumlah polong per tanaman, panjang polong, lebar polong, dan jumlah biji per polong. Terdapat galur-galur sawi yang mempunyai karakter unggul untuk bahan baku konsumsi dan industri.

Cropping Seasons

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.
