Abstract

Organic rice is believed to have better nutrition than conventional rice. Not all organic rice grain is consumed. Most of the organic cultivation yields will be used as seed. Viability test is one of the quality test of rice seed. Viability is seed vitality that can be shown as a physiological and biochemical phenomenon. Seed that have high vigor will achieve high productivity levels as well. The aims of this research was to analyze the quality of rice cultivar Menthik Wangi of organic farming yields. The quality of rice seeds was tested by measuring the viability of seed and crude fat content. The test results demonstrate the viability of the grain has a 100% germination, 100% growth potential maximum, 99.33%, simultaneity grew, 97.33% vigor index, T50 2.33, and seed moisture content 10.67%. The fat content was conducted by soxhlet method and analyzed by T-test. The results showed that organic rice has a higher fat content (0.53%) than non-organic rice (0.24%). It can be concluded that rice seed cultivar Menthik Wangi of organic farming has a higher viability and fat content than the non-organic rice grain.

Abstract

Red dragon fruit (Hylocereus polyrhizus Britton & Rose) is one type of cactus plant which is very potential as an ornamental plant and edible fruit. Flower is organ that play an important role in the process of breeding plants generatively. This reasearch aimed to study the anatomical structure of sepals and petals of red dragon fruit plants during flower development. The research stages included: sepals and petals sampling that held at various stages of flowering ; morphological observation (measurement length of sepals and petals); anatomical slides of sepals and petals cross section using the embedding method, anatomical observation and image capture of sepals and petals. The parameters observed were bud size, sepal length, petal length, sepal thickness, petal thickness, and tissue description composed. The results of this study indicated that buds have an increased development pattern. The increase in bud size is directly proportional to the stage of the bud. Sepal and petal are composed of epidermal tissue which form papillae, cryptophore stomata, secretory parenchyma space containing mucus, and tissues transport system is closed collateral.

Abstract

The rapid increase in human population reduces land productivity in urban areas. Verticulture is a way of planting in a vertical arrangement, such as for Capsicum frutescens L. This study aimed to examine the root anatomy and growth responses of C. frutescens L. Fourteen days old seedlings were grown in polybags on the ground and into vertical pots made of paralon pipe. Watering was given for every day, once in 3 days, and once in 6 days were apllied for 35 days, at elevation of 0 cm, 25 cm, 50 cm and 75 cm. The lower watering supply decreased the root diameter due to the thinner of cortical, xylem and stele tissues. Decreased  in plant height, leaf number, length-width of leaves, and fresh and dry weight of root-shoots were also observed in low watering plants, but there were increases in roots length and leaves chlorophyll content. The xylem was less developed in plants at higher position compared to the lower positon and this was more detected in plants with less watering. Decreasing plant growth occurs in conditions of water shortage and the higher plant layout on paralon, while root vascullar tissue was less developed in less watering and higher position plants.

Abstract

The haploid or double haploid plant of eggplants could be produced from microspore culture (embryogenesis of microspores). In the breeding programs, microspore can be developed into an embryo directly after exposure to stress treatment during cultured. Stress (temperature and starvation medium) is an important factor in the induction of embryogenesis microspore. This study aims to induced embryogenic microspores from eggplant CV. Gelatik. The stage late-uninucleate microspore (Vacuolate Microspore/VM) and early binucleate (Young Bicellular Pollen/YBP) are the suitable stages to induce multinucleate structure. There are 3 methods used in this research; 1) Determination of the stage development of microspore based on flower buds length and anther length. 2) Induction of embryogenic microspore on the pre-treatment and starvation medium. 3) After giving pre-treatment for 4 days, micropores were transferred to culture medium A2 at 28oC in dark conditions to induce the multicellular structures. This study reported that 50-68.51% of the VM+YBP stage obtained in the range of flower bud lengths of 10-17 mm, and 5.0-6.9 mm, the range of anther length containing VM+YBP of 50-77.48%. The pre-treatment heat shock at 33oC in the medium B for 2 days,  produced embryogenic microspores with a high percentage, that is about 50.19%, while microspores at 25oC and 4oC respectively 46.17% and 49.28%. Pre-treatment for 4 days at 4 oC, 25 oC,  and 33oC with the percentage of embryogenic microspores apiece 32.87%, 27.45%, and 37.34%. The multicellular (starlike) structure begins forming on the fifth day of incubation in culture medium (A2) after pre-treatment in B medium at 33oC.

Abstract

Salinity stress is known for adverse effect on plants. Priming with salicylic acid was able to improve plant performance under salinity stress. This study aimed to determine the effect of priming duration with salicylic acid on growth, leaf anatomy and the optimal priming duration for sweet corn seedlings (Zea mays L.) under salinity stress. The experiment was based on Completely Randomized Design with two factors and five replications. The first factor was priming duration with salicylic acid (2 mM) with four different durations (0, 12, 18 and 24 h). The second factor was the level of salinity (NaCl 0% and 3%). Parameters observed were germination percentage, plant height, root length, fresh weight, dry weight, chlorophyll content, leaf proline content, leaf anatomy and stomatal density. Data were analyzed with t-test, ANOVA and followed by Duncan’s test at 95% confidence level. The results showed that 18-h priming duration observed as the highest germination percentage which was 7% higher than control.  Priming for 24 h showed phytotoxic effect for sweet corn on the germination phase by reducing the percentage of germination. The application of salicylic acid mitigated the toxic effects of NaCl stress on maize seedlings and considerably improved root and shoot growth, photosynthetic pigments, fresh weight, dry weight, proline content, and stomatal density, as well as could maintaining the leaf anatomy. The optimal priming duration with salicylic acid for sweet corn seedlings under 3 % salinity was 18 h.

Abstract

Berbagai penelitian telah dilakukan untuk meningkatkan waktu pajang bunga potong demi meningkatkan nilai jualnya di pasar. Salah satu pendekatan yang digunakan oleh peneliti adalah dengan memicu pembentukan karakter anatomi jaringan xilem bunga potong yang lebih resisten terhadap embolisme, guna meningkatkan kemampuan rehidrasinya dengan memodifikasi kondisi lingkungan pada masa penanaman. Penelitian ini bertujuan untuk melihat pengaruh dari kondisi air yang berbeda pada masa penanaman terhadap karakter jaringan xilem, konduktivitas hidraulik batang, serta kemampuan rehidrasi dan waktu pajang bunga potong dari tanaman marigold (Tagetes erecta L.). Penelitian ini dilakukan menggunakan Rancangan Acak Lengkap (RAL), dimana bibit tanaman berusia empat minggu ditumbuhkan selama dua bulan dengan tiga volume penyiraman harian yang berbeda, yakni sebanyak 20%, 60%, dan 100% kapasitas lapang (KL). Data hasil penelitian kemudian dianalisis dengan analisis variansi (ANOVA) serta uji lanjut BNT (beda nyata terkecil) dalam taraf signifikansi sebesar 5% (α = 0,05). Hasil penelitian menunjukkan bahwa karakter struktural dan fungsional xilem pada tanaman Tagetes erecta L. hanya dapat terpengaruh oleh kondisi cekaman air berat (20% KL), yang berdampak negatif pada konduktivitas hidraulik batang, luas jaringan xilem, serta diameter lumen unsur pembuluh xilem. Akan tetapi, tidak ditemukan perbedaan yang signifikan pada karakter jumlah maupun frekuensi unsur pembuluh tersebut. Hasil penelitian juga menunjukkan bahwa meskipun didapati perubahan pada karakter struktural dan fungsional xilem batang, cekaman air yang diberikan pada akhirnya tidak berhasil mempengaruhi kemampuan rehidrasi maupun waktu pajang bunga potong yang dihasilkan.
