ABSTRAK. Penggunaan umbi benih untuk bahan perbanyakan bawang merah mempunyai beberapa masalah, antara lain ketidaktersediaan benih bermutu, produktivitas rendah, dan mahal. Salah satu alternatif teknologi yang potensial untuk dikembangkan sebagai benih ialah penggunaan biji botani atau true shallots seed (TSS).  Penelitian dilakukan untuk memproduksi benih bawang merah TSS di dataran tinggi melalui peningkatan pembungaan dan viabilitas serbuk sari menggunakan BAP dan boron.  Penelitian dilakukan di Kebun Percobaan Balai Penelitian Tanaman Sayuran Lembang, Jawa Barat (ketinggian 1.250 m dpl.) dari Bulan Agustus 2011 sampai dengan Februari 2012. Rancangan percobaan yang digunakan yaitu acak kelompok faktorial dengan tiga ulangan.  Perlakuan terdiri atas dua faktor, yaitu aplikasi benzil amino purin (BAP) 0, 50, 100, 150, dan 200 ppm dan boron 0, 1, 2, 3, dan 4 kg/ha.  Aplikasi  BAP diberikan tiga kali pada umur 1, 3, dan 5 minggu setelah tanam (MST), dan boron pada umur 3, 5, dan 7 MST. Hasil penelitian menunjukkan bahwa aplikasi BAP dapat meningkatkan pembungaan, viabilitas serbuk sari bawang merah, dan produksi benih TSS tetapi tidak meningkatkan mutu benih, sedangkan aplikasi boron efektif meningkatkan semua variabel yang diamati termasuk mutu benih TSS. Konsentrasi BAP yang optimum untuk menghasilkan produksi benih TSS ialah 37,5 ppm, sedangkan dosis boron yang optimum untuk menghasilkan bobot benih per plot yang tinggi dengan mutu benih sesuai standar sertifikasi mutu yaitu 2,88 kg/ha.  Hasil yang diperoleh pada perlakuan boron memberikan peningkatan sebesar 165,69% daripada kontrol. Hasil penelitian ini memberikan informasi teknologi produksi TSS yang dapat dikembangkan untuk memproduksi benih TSS bermutu tinggi. <br /><br />ABSTRACT. Rosliani, R, Palupi, ER, and Hilman, Y 2012. Benzyl Amino Purine and Boron Application for Improving Production and Quality of True Shallots Seed (Allium cepa var. ascalonicum) in Highlands. The use of bulb for propagation material of shallots has several problems including unavailability of quality seeds, low productivity, and expensive. One of the potential alternative technologies to be developed as seed is using true shallots seed (TSS). The aimed of research was to produce TSS in the highlands through increased flowering and pollen viability by using benzyl amino purine (BAP) and boron. The study was conducted at the Experimental Field, Indonesian Vegetable Research Institute (IVEGRI) in Lembang, West Java (altitude 1,250 m asl.), from August 2011 to February 2012. The factorial experiment was arranged in a randomized block design with three replications. The treatments consists of two factors, namely the application of BAP 0, 50, 100, 150, and 200 ppm and boron (0, 1, 2, 3, and 4 kg/ha). Benzyl amino purine application was given three times at  1, 3, and 5 weeks after planting (WAP), and boron at  3, 5, and 7 WAP. The results showed that application of BAP improved flowering, pollen viability, and seed production of TSS but did not improve seed quality, while boron application effectively increased all variables including the seed quality of TSS. The efficient concentration of BAP to improve TSS seed weight per plot was 37.5 ppm, while the optimum concentration of boron to improve TSS seed production with the good seed quality (according to the certification standards of seed quality) was 2.88 kg/ha. The yield obtained in the treatment of boron gave an increase of 165.69% compared to the control. The results provide information about TSS production techniques that can be developed to produce  the high seed quality of TSS.<br /><br />

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.

Abstract: Some desiccation techniques for harvesting wheat may affect seed quality. The objective of this study was to evaluate the effect of different desiccant herbicides applied to the wheat crop and their effects on the production and seed quality. The experiment was conducted with cultivar COODETEC 150 (CD 150) in two sites in Palotina (Paraná state, Brazil) with a randomized block design consisting of 7 treatments (desiccation herbicides) and 4 replications. Desiccation was realized when 50% of the plants were in stage 80 with seeds in powdery or mass consistency. The variables analyzed were percentage of moisture content after harvest, Yield, hectoliter weight, mass of 100 seeds, vigor, germination, fresh mass of seedlings, dry mass of seedlings and root length. The herbicides carfentrazone-ethyl and clethodim were the ones that promoted greatest reduction in vigor. The herbicide paraquat caused reduction in seedling length. There was a reduction in the mass of 100 seeds for glufosinate-ammonium, clethodim, diquat and carfentrazone-ethyl. Glufosinate-ammonium, paraquat, glyphosate, clethodim and diquat caused reduction in yield. Desiccation of Cultivar CD 150 at stage 80 is not recommended, since plant Yield and physiological seed parameters were adversely affected by herbicides.

Studies in vegetables show that fertilization influences seed production positively, however, when the quality of the seeds is analyzed, the results are mostly inconsistent. The objective of this study was to evaluate the effect of castor bean cake (CBC) dose splitting in top-dressing application on the production and quality of zucchini organic seeds, as well as its effect on the macronutrient content of fruits and seeds. The experimental design was a randomized block design and four replications. There were 13 treatments with four doses of CBC in top-dressing (1.7, 3.4, 5.1 and 6.8 t ha-1) per three applications (33.3-33.3-33.3%, 50-50% and 33-50-17%) and the control treatment without any kind of top-dressing fertilization. The study evaluated the number of ripe fruits per plant, the production (number and mass) of seeds per fruit and per plant, the mass of one hundred seeds, seed germination, first germination count, and macronutrient content in the diagnosis leaf, in mature fruits (without seeds) and seeds. The number of ripe fruits per plant was not affected by the CBC doses in top-dressing, neither by the splitting of the applications. It was observed that the number of seeds per fruit, mass of seeds per fruit and mass of seeds per plant showed quadratic behavior. Regarding seed quality, only the 1.7; 3.4 and 5.1 t ha-1 doses produced seed with superior quality than the other doses. In conclusion, the CBC doses increased the number of seeds per fruit, mass of seeds per fruit and per plant up to the 4.5t ha-1 dose, approximately.
