Seleksi cekaman salinitas kacang tanah dilakukan untuk mendapatkan tetua yang toleran terhadap salinitas dan memperbaiki sifat kacang tanah dalam kegiatan pemuliaan tanaman. Informasi genotip unggul kacang tanah toleran terhadap salinitas sangat diperlukan sebagai dasar pemilihan genotip tetua yang adaptif pada lahan salin. Penelitian ini bertujuan untuk memperoleh kacang tanah yang memiliki sifat toleran cekaman salinitas dan menentukan konsentrasi air laut yang dapat ditoleransi oleh tanaman. Penelitian ini dilaksanakan di Kebun Percobaan dan Penelitian, Jurusan Agroteknologi, Fakultas Pertanian Perikanan dan Biologi, Universitas Bangka Belitung, pada bulan Februari–April 2018. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola split plot dengan 2 ulangan. Petak utama adalah tingkat salinitas yaitu non-salin (kontrol), salinitas rendah, dan salinitas sedang. Anak petak adalah 5 genotip kacang tanah yaitu aksesi lokal (Belimbing dan Arung dalam) dan varietas nasional (Tuban, Kancil, dan Hypoma). Hasil penelitian menunjukkan bahwa varietas Hypoma memiliki karakter jumlah daun dan diameter batang yang paling baik, namun tidak toleran terhadap cekaman salinitas sedang. Aksesi Belimbing merupakan genotip toleran salinitas rendah berdasarkan nilai indeks toleransi cekaman salinitas. Selection of groundnut tolerant to salinity stress is carried out to obtain parent genotypes tolerant to salinity and improve the characteristics of groundnut in plant breeding program. The information of superior groundnut genotypes tolerant to salinity is necessary as the basic of genotypes selection adaptive in the saline area. The research aimed to obtain the groundnut tolerant to salinity stress and determine the concentration of seawater that can be tolerated by groundnut. This research was conducted at The Experiment and Research Field, Faculty of Agriculture Fisheries and Biology, University of Bangka Belitung, from February to April 2018.

He, J.-F., Goyal, R., Laroche, A., Zhao, M.-L. and Lu, Z.-X. 2013. Effects of salinity stress on starch morphology, composition and thermal properties during grain development in triticale. Can. J. Plant Sci. 93: 765–771. Triticale is a man-made cereal crop developed from a cross between wheat and rye. It has excellent agronomic traits for starch production on arid and semi-arid lands. This study investigated the effects of salinity stress on the alterations of starch morphology, composition and physicochemical properties during triticale grain development. Three triticale varieties (AC Certa, AC Ultima and Blue Alta) were treated with three levels of NaCl solutions (50, 100 and 200 mM), termed low salinity stress (LSS), moderate salinity stress (MSS) and high salinity stress (HSS), respectively. Reduction in seed weight and starch content were observed under salinity stress; the values decreased by 9–42% under MSS and 18–51% under HSS. MSS and HSS favored an increase of amylose synthesis and accumulation in triticale starch. Triticale starch synthesized under salinity stress showed a decreased population of small granules and an increased ratio on A-type to B-type granules. MSS and HSS decreased the peak temperature and increased the starch enthalpy, and an inverse relationship between salinity stress and a range of starch gelatinization temperature was also observed. This is the first report demonstrating that starch morphology, composition and thermal properties in triticale grains can be significantly affected by salinity stress.

Abstract Velvetleaf is an economically important weed in agronomic crops in Nebraska and the United States. Dicamba applied alone usually does not provide complete velvetleaf control, particularly when velvetleaf is greater than 15 cm tall. The objectives of this experiment were to evaluate the interaction of dicamba, fluthiacet-methyl, and glyphosate applied alone or in a mixture in two- or three-way combinations for velvetleaf control in dicamba/glyphosate-resistant (DGR) soybean and to evaluate whether velvetleaf height (≤ 12 cm or ≤ 20 cm) at the time of herbicide application influences herbicide efficacy, velvetleaf density, biomass, and soybean yield. Field experiments were conducted near Clay Center, Nebraska in 2019 and 2020. The experiment was arranged in a split-plot with velvetleaf height (≤ 12 cm or ≤ 20 cm) as the main plot treatment and herbicides as sub-plot treatment. Fluthiacet provided ≥ 94% velvetleaf control 28 d after treatment (DAT) and ≥ 96% biomass reduction regardless of application rate or velvetleaf height. Velvetleaf control was 31% to 74% at 28 DAT when dicamba or glyphosate was applied alone to velvetleaf ≤ 20 cm tall compared with 47% to 100% control applied to ≤ 12 cm tall plants. Dicamba applied alone to ≤ 20 cm tall velvetleaf provided < 75% control and < 87% biomass reduction 28 DAT compared with ≥ 90% control with dicamba at 560 g ae ha−1 + fluthiacet at 7.2 g ai ha−1 or glyphosate at 1,260 g ae ha−1. Dicmaba at 280 g ae ha−1 + glyphosate at 630 g ae ha−1 applied to ≤ 20 cm tall velvetleaf resulted in 86% control 28 DAT compared with the expected 99% control. The interaction of dicamba + fluthiacet + glyphosate was additive for velvetleaf control and biomass reduction regardless of application rate and velvetleaf height.
