<p><em></em><em>Identification of Indonesia sugarcane varieties tolerant to waterlogging has not been done extensively. Information on varieties tolerant to waterlogging is required for seedling establishment in waterlogged areas. The purpose of this research was to identify the sugarcane varieties responses to several duration levels of waterlogging at seedling stage. The planting materials used were collection of Sugar Factory Semboro including VMC 76-16, BL, PS 862, PS 864, and PS 881. This research was arranged in randomized complete block design (RCBD) with two factors and three replications. The first factor was 5 varieties; the second factor was waterlogging treatment with four levels, i.e. without waterlogging, 2, 4, and 6 weeks of waterlogging in the bucket. The results showed different level of tolerance to water logging among the varities. PS 881 and VMC 76-16 varieties were the most tolerant to waterlogging supported by its ability to maintain plant height, root volume, root and shoot dry weight after been waterlogged for 6 weeks. These varieties were also able to establish aerenchyme tissue and increased the stomatal density. PS 862 was the least tolerant variety to waterlogging. <br /><br />Keywords: aerenchyme, morphology, stomatal density, waterlogging, water stress</em></p>

Cabai (Capsicum annum L.) merupakan tanaman penting di Indonesia. Dalam 100 gram cabai segar mengandung sekitar 0,1-1,5% capsaicin yang merupakan tingkat kualitas cabai. Salah satu faktor yang mempengaruhi kadar capsaicin adalah kondisi stres salinitas. Kami mengamati efek salinitas dan waktu aplikasi pada hasil dan kandungan capsaisin. Tujuan dari penelitian ini adalah untuk mengetahui respon tanaman cabai dengan penambahan konsentrasi dan waktu aplikasi NaCl terhadap cabai dan kualitas. Penambahan konsentrasi NaCl sampai 9000 ppm dan waktu penerapan fase vegetatif NaCl dapat meningkatkan variabel kualitas kadar capsaicin dibandingkan dengan perlakuan kontrol.
