Abstract

Abstract. The efforts to increase rice production at East Borneo apart from the improvement of cultivation systems also could be done by using superior variety. Hybridization of rice plants has been done between the female local variety Pandan Ungu and the male local variety Roti. The research toward F2 progeny to find out the segregation patterns of inheritance of the characters number of tillers, plant height, stem leaves color, and palea-lemma color has been done at the paddy field at Desa Sidomulyo, Kecamatan Anggana, Kabupaten Kutai Kartanegara since October 2016 until March 2017. The F2 identification method that was used is single plant selection methods, based on Standard Evaluation Systems (SES) for Rice. Suitability test between observed value and expected value used Chi-square test, and to see the characters segregation pattern ratio used Mendelian genetics analysis. The inheritance character of stem leaves color was managed by two pairs of genes followed segregation ratio 9:6:1 with the action epistatic genes with cumulative effect, the inheritance of palea-lemma character was managed by two pairs of genes followed Mendelian ratio 13:3 with the action epistatic dominant-recessive, while the characters plant height and number of tillers was managed by polygenes so the inheritance patterns was not following Mendelian ratio.

Abstract

Ulin (Eusideroxylon zwageri) is one of the native plants of Indonesia whose growth is spread in tropical forest, among others in southern Sumatra and Kalimantan. Based on the results of the 1998 Asia Regional Workshop meeting held at the Hanoi (Vietnam) International Union for Conservation of Nature and Natural Resources (IUCN), it was determined that ironwood is on Vulnerable A1cd + 2cd status which means sensitive or is facing a high risk of extinction. Tissue culture is a technique that needs to be applied to overcome the problem of ironwood regeneration initiation. However, the concentration of tannin with high concentration so that the formation of browning which leads to the death of ulin tissue is one of the causes of the low success of ironwood tissue culture. This study was formulated based on the potential of activated charcoal and vitamin C to overcome browning, so that it can significantly affect the growth of Ulin regeneration initiation (Eusideroxylon zwager). The analytical method used is Observation of Qualitative Parameter Treatment, namely explant color and the quantitative parameter observed is the number of explants that have browned and not browned in this case are calculated in percent. Based on the results of the research that has been done, obtained methods to overcome browning in ulin explants (Eusideroxylon zwageri) which is divided into 2 stages. In stage 1 (pre-condition) browning can be overcome with a 100% success rate, explants soaked for 24 hours in 50% MS liquid media with pH 4. In stage 2, browning can be overcome with a 100% success rate on 100% MS solid media addition of BAP 1.0 mg / L with A2B3 treatment (Vitamin C / 1 mg / L ascorbic acid, 4.00 g / L activated charcoal) placed in the dark room.

Abstract

Red Chilli is commodity of vegetable that has high economic value, but still has slow productivity. The objective of this study was identify the effect of indigenous microorganism (EM 4) application and compost to increased the growth and yield of Red Chilli Plant (Cappcicum annum L) on Ultisol. Field trial was conducted on Ultisols in Horticulture Experimental Station, BatuahLoajanan, Kutai Kartanegara. The soil was characterized by low fertility status. The amount of organic matter and microbial acivity are very low. This trial was started on January until April 2017 using Split Plot Design with three replications Main plot consisted of two levels treatment i.e. without EM-4 (E0) as control and Effective Mikroorganisms-4 (E). Sub-plot was four rates of organic compost i.e. 0, 10, 20 and 30 tons ha-1 and chili was used as test plant.Results indicated that EM-4 treatment showed a significant effect on fruit yield of chilli. It increased the fruit yield 38 percent compare to control. Compost application significantly increased on fruit yield. The relationship between unfermented compost rate and fruit yield shows a linear regression YE0 = 1.699 + 0.047 X (r = 0.95) and quadratic regression for EM-4 fermented compost YE1 = 1,175 + 0,319 X – 0.007 X2(R2 = 0.603). Optimum compost rate was 23 ton.ha-1.To increased fruit yield of chilli, EM-4 fermented compost should be applied into and it can decreased compost rate application.
