Brassica Oleracea L

The cabbage whitefly (CW), Aleyrodes proletella (L.) (Hemiptera: Aleyrodidae), is an important pest in Brassica oleracea L. crops. Little is known about the mechanisms of resistance to CW of savoy cabbage and kale cultivars. Light microscopy (LM) and scanning electron microscopy (SEM) analysis were used to determine the relationship between the morphological and anatomical features of savoy cabbage (Brassica oleracea L. convar. capitata (L.) Alef. var. sabauda L.) and kale (Brassica oleracea L. convar. acephala (DC.) Alef. var. sabellica L.) leaves and host suitability to colonization by CW. Two kale cultivars, “Redbor” and “Starbor”, and two savoy cabbage cultivars, “Gloriosa” and “Alcosa”, that differed in the degree of infestation by A. proletella were taken for histological analysis. The lowest infestation by all forms of A. proletella was observed on savoy cabbage cultivar “Alcosa” and kale cultivar “Starbor”. The reduced colonization by cabbage whitefly may be related to the structure of the epidermis and the anatomical features of the leaf. The leaves of “Starbor” and “Alcosa” had more folds in the epidermis, less numerous but larger stomata, and a more compact mesophyll structure compared to “Redbor” and “Gloriosa”. In both analysed species, there was no clear relationship between the thickness of the abaxial epidermal layer, thickness of the lamina, number of vascular bundles, and degree of infestation by the cabbage whitefly. This study identified promising sources of resistance to A. proletella among cultivars of savoy cabbage and kale. Varying infestation by CW was associated with morphological and anatomical characteristics of leaves. Further study is needed to confirm the relationship between insect resistance and leaf surface and morphological characteristics of leaves in a broader range of Brassica spp.

Latar Belakang: Beta-karoten merupakan salah satu isomer karoten yang bisa ditemukan pada sayuran berwarna hijau tua atau kuning tua (seperti wortel dan brokoli). Brokoli merupakan sayuran yang memiliki kandungan beta-karoten yang cukup tinggi, yaitu 623 IU/100 gram. Namun, proses pengolahan brokoli menjadi hidangan dapat menurunkan kandungan beta-karotennya. Tujuan: Mengetahui pengaruh teknik pengolahan terhadap kandungan beta-karoten pada brokoli. Metode: Jenis penelitian ini adalah observational di laboratorium. Penelitian ini menggunakan rancangan acak sederhana dengan dua kali pengulangan dan satu unit percobaan. Teknik pengolahan yang dilakukan adalah merebus, mengukus, dan menumis. Brokoli mentah digunakan sebagai kontrol. Penelitian dilakukan pada bulan Februari–Maret 2017. Analisis kadar beta-karoten dilakukan di Laboratorium Chem-mix Pratama Yogyakarta dengan metode spektrofotometri. Hasil: Kadar beta-karoten tertinggi terdapat pada brokoli mentah diikuti dengan brokoli yang ditumis, dikukus dan direbus. Persen penurunan kadar beta-karoten yang direbus, dikukus dan ditumis dibandingkan dengan brokoli mentah masing-masing sebesar 45,87%, 33,52% dan 22,25%. Ada penurunan kadar beta-karoten yang signifikan setelah direbus, ditumis, maupun dikukus dibandingkan dengan brokoli segar (p<0,05). Kesimpulan: Kadar beta-karoten pada brokoli mengalami penurunan setelah dilakukan pengolahan dengan cara direbus, dikukus, dan ditumis. Merebus mengakibatkan penurunan kadar betakaroten terbanyak dibandingkan dengan kedua proses lainnya.
