Abstract

The objective of the research is to identify normal and abnormal flowers on oil palm clones from tissue culture in PPKS plantation in Dharmasraya District. This research used descriptive method and the data were taken by purposive sampling. Forms of normal and abnormal flowers were described, as well as the stages of flowers development. Result indicated that normal female flowers have 3 stigmas and 3 lobes, while abnormal female flowers have more than 3 stigmas and 3 to 7 lobes. In comparison, normal female flowers have 6 circles of corollas while abnormal female flowers have 7 circles with additional carpels on corolla. There are three kinds of abnormalities found i.e.: transvestite coat, heavy coat, and very heavy coat (abort). The percentages of normal flowers is 80% while the abnormal flowers is 20%.

Abstract

The soil contaminated by lime mud has a high content of Ca and Na. It affects the availability of nutrients within the soil. Calcareous soil conditions tend to disperse, sensitive to washing and erosion. Meanwhile, the availability of P nutrients is also low due to the binding of P by Ca in the form of (Ca3PO4)2 that leads the soil productivity to be low. Organic material is a soil enhancer which has complete function, easily available, abundant and can increase P nutrients especially for the plants in the long-term. Hence, the objective of this research was to observe the response of increasing level of soil P contaminated by lime mud and P uptake in maize plant tissues toward the treatment of adding organic material. The research design used in this study was factorial randomized block design comprising of two factors and three replications. The first factor was the source of fertilizer (1) no fertilizer (P0), (2) animal waste bokashi (P1), (3) straw bokashi (P2), (4) guano organic (P3), and (5) NPK inorganic (P4). The second factor was (1) polluted soil (T1) and (2) unpolluted soil (T2). The results revealed that combination of fertilizer types and planting media could significantly increase soil Ca and wet weight of maize crops, additionally gave impact indirectly toward soil pH, P and C-Organic content in the soil, P uptake, plant height, root volume, and dry weight of maize crops. By doing a treatment of giving animal waste bokashi fertilizer combined with contaminated soil media, it apparently produced better results than controlling, and resulted better product than treating them with straw bokashi fertilizer and guano organic fertilizer.

Abstract

Specific changes in morphology, anatomy, biochemistry and molecular occur due to changes in light intensity. Changes in growth is closely related to the mechanism of plant resistance when low light conditions. In addition, the environmental stress conditions of supply nutrients plants need in order to remain able to grow optimally. This experiment was conducted in experimental garden Sawah Baru, Post-harvest Laboratory and Micro-engineering Laboratory Bogor Agricultural University, beginning in December 2014 until July 2015. This experiment was aims to determine the effect of shade and fertilization on the growth and change of morpho-anatomy of leaves jack bean. The experiment was arranged in a split plot design based on randomized complete block design. Shade as the main plot that consists of three levels: without shade, shade 25% and 50% and combination doses of fertilizer as a subplot which consists of three levels ie: 50 kg urea ha-1 + 100 kg SP-36 ha-1 + 75 kg KCl ha-1, 75 kg urea ha-1 + 125 kg SP-36 ha-1 + 100 kg KCl ha-1, 100 kg urea ha-1 + 150 kg SP-36 ha-1 + 125 kg KCl ha-1.The results showed increased percentage of shade caused etiolation, reduction number of branches, change the leave size, depletion of palisade tissue which decreases the thickness of the leaves, and decreased of pod/plant.Whilefertilizationfactoronlyinfluence onthe thickleaves andthickpalisade.

Abstract

The reseach was conducted in the Kebun Pembibitan Kelompok Tani Budidaya, Sungai Dareh, Dharmasraya fromJuly to October 2016. The aim of the study was to investigate the interaction between grafting and concentration ofbenzylaminopurine, to measure the growth of grafts treated with benzylaminopurine and to determine the bestconcentration of benzylaminopurine. A completely randomized factorial design was used. The first factor was thetype of bud (green or brown) and the second factor was benzylaminopurine concentration (0, 5, 10, 15, and 20ppm). The best concentration of benzylaminopurine for green buds was 10 ppm whereas the best concetration was20 ppm for brown buds.

Abstract

Conductivity test is a test to physically measure the electrolyte leaking from seeds and be classified as vigor test. However, some factors may affect the result of the test; therefore, standardized procedures should be defined for its accuracy and consistency. The research reported here was aimed at obtaining specific method of conductivity test for wheat seeds and to study the correlation between conductivity test result with seed germination and field emergence. The experiments were conducted at the laboratory of BBPPMBTPH, Cimanggis, Depok from February to June 2013. The experiment was designed to identify the correct amount of wheat seeds and the volume of water used to soak the seeds. The experiment was assigned according to a completely randomized design (CRD) with 20 wheat seed lots and three replicates. Data collected including seed germination (SG), vigor index (IV) or First Count Test (FCT), field emergence (FE) at 8, 14, and 21 days, tetrazolium test (TZ), and conductivity test for nine combinations of wheat seed amount and the water volume for soaking (50, 75, and 100 seeds in 100, 150, and 200 mL of water). Results show that soaking 75 wheat seeds in 200 mL of water was best for conductivity test. This soaking condition resulted in negatively significant correlation between seed germination and field emergence. Moreover, low value of conductivity resulted in high values of SG, IV, FE, and TZ. Wheat seed germination and field emergence can be estimated using the equations of y = 0.028x2 – 3.321x + 104.9 and y = 0.022x2 – 2.704x + 87.96, respectively.

Abstract

Penelitian dengan judul seleksi toleransi padi lokal generasi M2 hasil iradiasi sinar gamma terhadap cekaman Fetelah dilaksanakan pada lahan Nagari Sialanggaung Kabupaten Dharmasraya. Pelaksanaannya dilakukan sejakbulan Agustus sampai Desember 2010. Tujuan penelitian ini adalah menseleksi padi lokal generasi M2 yang toleranterhadap cekaman Fe.Metode yang digunakan pada penelitian ini adalah metode deskriptif. Pengamatan gejalaserangan keracunan Fe dianalisis berdasarkan anjuran Komisi Nasional Plasma Nutfah, (2003). Pengelompokanskor menjadi toleran atau peka sesuai dengan IRRI (1980) dalam Abifirin (1986) dimana tanaman dengan skor 0-4termasuk toleran dan skor 5-9 termasuk peka. Sedangkan untuk data tinggi tanaman (cm), jumlah anakan total(batang), panjang malai tanaman (cm) dan bobot 100 biji (g) akan dibandingkan dengan tanaman induknya(kontrol).Hasil penelitian dapat disimpulkan bahwa adanya pengaruh mutasi terhadap cekaman Fe tanaman padikultivar Sijunjung, Kuriak Kusuik dan Anak Daro. Hal ini dapat dilihat dari persentase tanaman yang toleranterhadap cekaman Fe lebih besar apabila dibandingkan dengan tanaman induknya (kontrol), sehingga tanamandapat diseleksi untuk dilanjutkan ke penanaman M3, sedangkan untuk kultivar Anak Daro tidak dapat dilanjutkan kepenanaman M3 karena pada saat memasuki masa generatif tanaman kultivar Anak Daro terserang hama werengyang menyebabkan tanaman mati.
