No full textThe study aimed to obtain morphophysiology information on fruit-drop events in chili plants on application of plant growth regulator (PGR) auxin (IAA and IBA) and gibberellins. The study was arranged based on a split-plot design in a randomized block design with 3 replications. The main plot is 3 types of PGR namely IAA, IBA, and GA3. The subplots are 5 levels of concentrations (ppm): 0, 25, 75, 50, and 100. The data were analyzed using STAR software and Smallest Significant Difference (LSD) 5%. The results showed that the application of PGR and concentration did not significantly affect the number of attached and abscised flowers. However, the application of PGR resulted in a higher number of attached flowers than the abscised flowers. Giving IAA 25 ppm produced the highest number of fruits compared to other IAA concentrations. Increasing the concentration of GA3 tends to increase the number of attached fruits and the highest at 100 ppm GA3. The interaction between PGR and concentration significantly affected the weight per fruit. The treatment of GA3 100 ppm produces the highest weight per fruit. Increasing the concentration of auxin tends to reduce the weight per fruit. The IBA 100 ppm decreases the length of chili.Penelitian bertujuan mendapatkan data dan informasi morfofisiologi kejadian gugur bunga dan buah (fruit-drop) pada tanaman cabai terhadap pemberian zat pengatur tumbuh (ZPT) auksin (IAA dan IBA) dan GA3. Penelitian disusun berdasarkan Rancangan Petak Terpisah dalam rancangan acak kelompok dengan 3 ulangan. Petak utama adalah 3 jenis ZPT yaitu IAA, IBA, dan GA3. Anak petak yaitu konsentrasi perlakuan yang terdiri dari 5 taraf (ppm) yaitu 0, 25, 50, 75, dan 100 ppm. Data yang diperoleh dianalis menggunakan software STAR dan jika terdapat beda nyata diuji lanjut dengan Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan IAA, IBA, dan GA3 serta konsentrasi perlakuannya tidak berpengaruh nyata terhadap jumlah bunga tinggal maupun bunga gugur pada tanaman cabai besar. Namun, hasil penelitian menemukan bahwa perlakuan ZPT menghasilkan jumlah bunga tinggal yang lebih banyak dibandingkan bunga gugur. Pemberian IAA 25 ppm menghasilkan jumlah buah tinggal tertinggi dibandingkan konsentrasi IAA lainnya. Peningkatan konsentrasi GA3 cenderung meningkatkan jumlah buah tinggal dan tertinggi pada konsentrasi GA3 100 ppm. Interaksi antara jenis ZPT dan konsentrasi pemberiannya berpengaruh nyata terhadap bobot per buah. Perlakuan GA3 100 ppm menghasilkan bobot per buah tertinggi. Peningkatan konsentrasi auksin cenderung menurunkan bobot per buah. Pemberian IBA 100 ppm menurunkan panjang buah cabai besar
Gene Pyramiding for Brown Planthopper Resistance-related Traits, Early Maturity and Aroma of Rice Assisted by Molecular and Phenotypic Markers
Full text linkThe brown planthopper (BPH)-resistant rice, early maturity, and aromatic are expected by both farmers and consumers. The traits have been combined through gene pyramiding and some promising rice genotypes obtained. However the genetic control of BPH resistance and maturity is quantitatively inherited, it is therefore both molecular and phenotypic assessments would be tremendously helpful in selecting promising genotypes. The study aimed to obtain genotypes with such valuable traits. Rice lines were analyzed using molecular markers i.e., RM586, RM589, RM8213 (BPH resistant gene markers); RM7610 and RM19414 (early maturity markers), and IFAP (Internal Fragrant Antisense Primer) for detecting aromatic, and INSP (Internal Non-fragrant Sense Primer) for non-aromatic rice. Phenotypic assessment was performed for brown planthopper resistant-related traits, such as chlorophyll content, stomatal conductance, and trichome density. Other evaluations were heading date and aroma (using 1.7% KOH solution). Results showed that molecular markers for evaluating BPH resistance genes (Bph3, Bph4, Qbph4, and Bph17), aroma (fgr gene), and heading date (Hd2 and Hd3 genes) could differentiate genotypes, and they serve as perfect markers, except for heading date markers. Seven genotypes i.e., #2, #3, #4, #5, #6, #10, and #11 were related to all traits expected based on molecular marker analysis. Meanwhile, genotypes #1, #2, #4, #6, and #11 were similar to their parents based on phenotypic analysis. Pyramiding program based on molecular and phenotypic markers enables us to combine three valuable traits into one rice genotype as presented in this studyThe brown planthopper (BPH)-resistant rice, early maturity, and aromatic are expected by both farmers and consumers.

Effect of Watering Frequency on The Growth and Yield of Oyster Mushrooms (Pleurotus ostreatus)
Full text linkOyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom. Banjarbaru City tends to have high temperatures with a relative humidity that tends to below. This is quite different from the requirements for growing oyster mushrooms which require low temperatures with relatively high humidity. One of the easiest and cheapest methods to maintain temperature and relative humidity to remain ideal and appropriate is to water the surrounding oyster mushrooms growing media, so knowledge of the most appropriate and ideal watering frequency for growth and development of oyster mushrooms is needed. The environmental design used was a Completely Randomized Design (CRD), a single factor with 4 treatments, 5 replications, so that 20 experimental units were obtained. The treatments are p1 = once watering per day, p2 = twice watering per day, p3 = three times watering per day, p4 = four times watering per day. The result showed that the watering frequency showed significant difference to the growth time of oyster mushroom shoots and the wet weight of oyster mushrooms. The best treatment in accelerating the growth time of oyster mushroom shoots and increasing the wet weight of oyster mushrooms is four times watering frequency per day.Oyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom.
