Abstract

Rice is a cereal crop that belongs to the graminae family of high economic value, and is the main food for more than a portion of the world's population. This study aims to determine the relationship genetic of rice in Kampar by RAPD marker. Eight genotypes of rice from district in Kampar were amplified using eight primers (OPA 5, OPB 7, OPC 19, OPD 2, OPD 3, OPD 8, OPD 11, and OPD 13). The analysis of molecular data was performed by using NTSys pc -2.02 and GenAlex 6.1 . The results of the amplification of rice produced 48 loci with DNA band sizes obtained ranging from 350-1700 bp. The average percentage of polymorphic loci of the eight primers was 49.80%, where the highest percentage of polymorphic loci produced by OPA-7 primer was 75%, while the lowest polymorphic locus percentage was observed in OPD-13 primer which was 14.28%. The value of genetic distance between rice from Kampar in this study is in the range of 0.06 - 0.37. At a genetic distance of 0.79, rice plants can be grouped into two groups, namely the first group consisting of sokan and coku. The second group consisted of suntiong, korean , cupak putio, kuniong, jangguik, and cupak tenggi. The results of this study are expected to be taken into consideration in developing rice breeding strategies in the future.

Abstract

Christmas palm is a plant that has high economic value as an ornamental plant and is in great demand. Christmas palm seeds begin to germinate 3-4 weeks after planting, slow germination because of to seeds experiencing physical dormancy. To break dormancy can be done by scarification and immersion GA3. The purpose of this study was to determine the effect of scarification and GA3 on the germination and growth of christmas palm seedlings and the interaction between the two treatments. This research was carried out from December 2017 to March 2018 on experimental Field and Agronomy Laboratory Faculty of Agriculture and Animal Science State Islamic University Sultan Syarif Kasim Riau. The method used Randomized Complete Block Design (RCBD) with two factors and four replications. The first factor was the scarification (control and with scarification) and the second factor is immersion GA3 (0 ppm, 150 ppm, 300 ppm and 450 ppm). The results showed that scarification by means of sandpaper can increase the growth rate and height of the christmas palm plant.The dipping of GA3 with concentration of 450 ppm for 2 hours is the best concentration for growth speed. There was no interaction between scarification and GA3 immersion on all observational parameters both in germination and in the nursery of chritmas palm plants on the land.

Abstract

The problem of propagation of Punica granatum, was hard seed, and it difficult to germinate. One of the efforts to solve the problem is using H2SO4 as to breakdown of the hard seed. This study aimed to obtain the best concentration of H2SO4 and soaking time, as well as the interaction between H2SO4 concentration and soaking time on the germination of  Punica granatum seeds. This study used a completely randomized design (CRD) consisting of 2 factors. The first factor is H2SO4 concentration (0%, 20%, 40%, 60%, and 80%), and the second factor is soaking time (10, 15, and 20 minutes). Parameters observed were germination, germination rate, vigor index, germination height, root length, weight of sprouts, and dry weight of Punica granatum sprouts. The results showed the use of water was the best treatment on germination (85.30%), germination rate (17.37 days), vigor index (2.24%), germination height (7.80 cm), and root length of Punica granatum (7.05 cm), soaking time did not effect the germination of Punica granatum, and the interaction between the use of water and the soaking time 15 minutes was the best treatment on the parameters of fresh weight of sprouts (0.17 g) and dry weight of Punica granatum sprouts (0.13 g).
