Kelapa merupakan tanaman serba guna, kelapa genjah sesuai dijadikan sebagai kelapa muda segar dan lebihÂ potensial disadapÂ niranya. Indonesia memiliki kondisi iklim yang unik, menyebabkan kekeringan. Kelapa genjah rentan terhadap kekurangan air, sehingga perlu dilakukan upaya mengatispiasi kekeringan. Salah satu upaya dalam menghadapi kekeringan dengan pemberian unsur kalium. Tujuan penelitian adalah mengetahui pengaruh dosis pemberian pupuk kalium terhadap respon pertumbuhan beberapa varietas kelapa genjah di pembibitan dalam menghadapi kekeringan. Penelitian dilaksanakan di Rumah Kaca Balai Penelitian Tanaman Palma (Balit Palma) di Mapanget, Sulawesi Utara. Penelitian dilaksanakan bulan Mei sampai November 2020. Menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua faktor. Faktor pertama adalahÂ 4 varietas kelapa genjah. Faktor kedua adalahÂ 5 perlakuan dosis pupuk KCl. Hasil penelitian diperoleh pemberian dosis pupuk kalium 110 g KCl menunjukan kecenderungan lebih baik pada parameter pertambahan tinggi tanaman pada 1 dan 2 bulan kekeringan. Dosis pupuk kalium 165 g KCl (P3) menunjukan kecenderungan lebih baik pada parameter pertambahan diameter batang pada 2 bulan kekeringan dan volume akar. Perlakuan kalium tidak berpengaruh nyata pada pertambahan diameter batang pada 1 bulan kekeringan, penambahan jumlah daun pada 1 dan 2 bulan kekeringan, kandungan klorofil, berat kering tajuk, dan berat kering akar. Pada perlakuan Varietas kelapa genjah tidak terdapat perbedaan yang nyata antara varietas pada semua parameter pengamatan dan hanya berbeda nyata pada kandungan klorofil.Â

This study aims to observe the growth in the sprouting phase and to observe the sulforaphane content in the growth stages of broccoli sprouts treated with kinetin on MS media. The research was conducted at the Laboratory of Biotechnology, Faculty of Agriculture, Sam Ratulangi University and the Laboratory of Department of Chemical Engineering, State of Malang. The study used a Completely Randomized Design (CRD) with 4 treatments and 9 replications, nam ely without kinetin, 0.5 ppm kinetin, 1 ppm kinetin, 1.5 ppm kinetin. The variables observed were the time of sprout formation, sprout height, sprout weight, sulforaphane content. The results of this study showed that the sulforaphane content was not affected by the height and weight of the sprouts but the kinetin concentration, the higher the concentration given, the higher the sulforaphane content.

ABSTRACTQuantitative character was seen as a form of continuous distribution, observed by measuring, had many controller genes, influenced by environmental factors very easily and selected through data analysis. Qualitative character was seen as a form of rigid distribution, observed visually, had one or two controller genes, influenced by environmental factors very scarcely and selected visually. Genetic variation was a variation that happened by the changes of genetic substances which were permanent and were always inherited to its heredity. This research was conducted in Winorangian Village, Tombatu Subdistrict, Minahasa Tenggara Municipality. The objective of this research was to study about the variety of quantitative and qualitative character of five varieties of mung bean.This research was done by using Randomized Block Design (RBD), with five ways of handling and four experiments. As research instruments, the researcher used five varietiesof mung bean: Sriti Variety (V1), Merak Variety (V2), Kenari Variety (V3), Perkutut Variety (V4), and Betet Variety (V5).The research finding showed that those five varieties of mung bean had narrow type of genotype type, where as the genotype type is lesser or equals to the double of the number of the standard deviation of genotype type. It indicated that the inherited character from the predecessor was very strong (homogen) and influenced by environmental factors very scarcely.Keywords: Quantitative Character, Qualitative Character, Genetics Variation, Mung Bean

ABSTRACT The purpose of this study was to determine the purity level of the F2 white kernel Manado yellow line using the Ear To Row Method. This research was cunducted in april until august 2017 in Kalasey 1 village, District of Mandolang, Minahasa Regency, North Sulawesi Province. In this study the observational variables included the percentage of white kernal color and other color percentage of red beard color. In research on cobs one with white clover color characterization, the percentage of white kernels ( 100% in one ear) was 95,85% and the reaming 4,14% were cobs which had a white-yellow mixed kernel color. On the white cactus plant cobs obtained a percentage of 63,2% and the red clover obtained with a percentage of 36,8%. In the second ear with red clover, the percentage of white kernel color (100% in one ear) was 96,01% and the remaining 3,39% were cobs which had a mixture of yellow and white. Crop cobs with white taffy obtained a percentage of 22,09% and cobs of plants with red clover obtained a percentage of 77,91%. The results of the purification of F2 lines yellow Manado corn white kernels using the ear to row method shows that there are still a few corn cobs of corn plants that produce yellow white mixed kernel/ seed. This research suggested that further refining is done for the yield of F2 Manado yellow white kernel corn on cob, producing 100% white kernels to determine the level of purity.

This study aims to determine the effect of using Trichoderma sp on polyembryony of honey Siamese orange seeds. This research was conducted at the Plant and Environment Laboratory, Sub-Laboratory of Genetics and Plant Breeding, Faculty of Agriculture, Sam Ratulangi University, Manado. The design of this study used a completely randomized design (CRD) with 2 factors, namely the concentration of trichoderma sp. T1 (109), T2 (108), T3 (107) and immersion time, W1 (24 hours), W2 (16 hours), W3 (8 hours). The variables observed were: Germination Power (Viability), Polyembryony, Root Weight. The results of the research showed that Trichoderma sp at a dose of 108 and a soaking time of 8 hours obtained the highest germination of Siam Honey orange seeds. From the results of the polyembryony research on honey Siamese orange seeds using Trichoderma sp, 40% polyembryony was obtained, whereas polyembryonic growth on honey Siamese orange seeds without Trichoderma sp obtained 16,6% polyembryony.
