Abstract

Triploid watermelon seeds are produced from the crossing between watermelon diploid as males and tetraploid watermelons as females. The success of triploid seed formation is influenced by the success of pollination determined by pollen viability which is characterized by the period of anthesis and peptic receptivity by the time of pollination. This experiment was conducted in Jember  on 2018. The Factorial Randomized Block Design, 3x3  with three replications, was concucted to determine the effect of male anthesis period and pollination time on the success rate of seedless watermelon seed formation. The results showed that no significant interaction of the male anthesis period and the time of pollination effect. Pollens harvested during pre anthesis give the best pollination results. On the other hand, the best pollination can be done at 07.30 – 08.30 am  Keywords: anthesis, pollination, seeds, seedless watermelon.

Abstract

Tomato was classified as a climacteric fruit with a fast ripening period andthen followed by the increase of fruit softening. The inhibition of fruit softening was needed to maintain the quality and shelf life of the fruit. One of the way to inhibit the tomatoes softening was calcium application. However, the best concentration and timing of calcium application for tomato was still limited. The aimed of research was to determine the best combination of concentration and time of application of calcium chloride (CaCl2) to the physicochemical of tomato. Experiment was arranged in factorial completely randomized design (CRD) with two factors and three replications. First factor was concentration of CaCl2 which consisted of 5 levels (0 M; 0.3 M; 0.6 M; 0.9 M; 1.2 M), while the second factor was application time of CaCl2 (pre- and post-harvesting). The results showed that there was no interaction between concentration and application time of CaCl2 to the physicochemical of tomatoes. Treatment of CaCl2 1.2 M could increased fruit calcium content, inhibited weight loss and fruit softness, increased total titrated acid content, and inhibited the degradation of vitamin C. The application time of CaCl2 in pre- and post-harvest was not significantly different in term of physicochemical properties. Keywords: fruit softness, quality, weight loss, shelf life, vitamin C
