Ekstrak daun stroberi (Fragaria x ananassa var Duchesne) dilaporkan memiliki aktivitas tabir surya yang baik. Namun, diperlukan formulasi dosis sesuai untuk tahap selanjutnya. Oleh karena itu, penelitian ini bertujuan memformulasi emulgel dari ekstrak etanol menggunakan uji sifat fisik, stabilitas, dan nilai SPF. Daun diekstraksi dengan metode refluks 96%. dianalisis kandungan kimianya KLT. Emu...

The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids. To elucidate the ancestries of these octoploid species, we performed a phylogenetic analysis using intron-containing sequences of the nuclear ADH-1 gene from 39 germplasm acces...

The relative susceptibility of 44 genotypes of wild Fragaria L. and commercial cultivars of strawberry Fragaria ×ananassa Duch. to Meloidogyne hapla Chitwood and Pratylenchus penetrans (Cobb) Filipjev & Shuurmans Stekhoven was evaluated in the greenhouse. Eleven genotypes were highly resistant to populations of M. hapla from Washington State and Oregon, with Rf values (initial nematode density/...
