Daftar Isi:
  • Limited land for agriculture in high altitude causes farmers of tomato switch their crop to low altitude. Due to this, plant breeder assembled low altitude cultivars of tomato. Climate change results drought stress. Plant may show different distribution assimilates under the drought stress. This study aimed to determine the responses of distribution assimilates of the low altitude cultivars of tomato under drought stress and determine for the tolerant cultivars of tomato under drought stress. The research conducted at the Experimental Station, Faculty of Agriculture, Gadjah Mada University, Banguntapan, Bantul , Yogyakarta from November 2012 to January 2013. The experiments used split plot design with two treatments, drought stress as the main plot and low altitude cultivars of tomato as subplot. The design consisted of three replications. Drought stress treatment consisted of 4 levels, that is 1, 2, 4, and 8 days of watering interval. Cultivars treatment consisted of 7 different cultivars. The cultivars are Zamrud , Permata, Mirah, Tombatu, Tyrana, Ratna, and Tymoty. The results showed that the increasing of interval watering causes decreased growth and yield. The analysis of cluster resulted two group of cultivars. The one of the group consisted of Zamrud, Permata, and Ratna and the other group consisted of Mirah, Tyrana, Tombatu, and Tymoti. Based of tottaly fruits weight, Zamrud, Permata, and Ratna included into the group of tolerant cultivars under drought stress. The totally fruits weight of the three cultivars decreased as following 10.16%, 22.06%, and 41.26%. Mirah, Tyrana, Tombatu, and Tymoty included into the group of untolerant cultivars under drought stress with decreased of totally fruits weight as following 64.99%, 66.02%, 71.81%, and 82.36%.
