Yield performance of eight wheat cultivars (Triticum aestivum L.) was compared in two-row plots with 38 cm between rows and in three-row plots with 19 cm between rows. The cultivar × row spacing interaction was nonsignificant in each of four tests. The range of cultivar yield from two-row plots as a percentage of the mean was similar to that for cultivar yield from three-row plots. Duncan’s multiple range test was applied to yield of cultivars grown in two-row and three-row plots. The grouping of cultivar yield from two-row plots was very similar to the grouping of cultivar yield from three-row plots. The standard error of a mean and coefficient of variation were consistently lower for three-row plots than for two-row plots. The relationship between yield performance of a line in two-row plots and three-row plots was positive, such that two-row plots would be suitable for early generation progeny yield tests with final evaluation in multiple-row plots.

Penelitian ini bertujuan untuk mengetahui pertumbuhan, hasil, dan kualitas hasil tanaman gandum yang maksimum di dataran medium melalui pemberian kalsium klorida dan asam salisilat dengan interval waktu yang terbaik. Percobaan dilakukan sejak Maret hingga Juli 2015 di Kebun Percobaan Fakultas Pertanian Univer-sitas Padjadjaran, Jatinangor, dengan ketinggian tempat yaitu ± 750 m di atas permukaan laut. Rancangan percobaan adalah Rancangan Acak Kelompok yang terdiri dari lima perlakuan dan diulang empat kali sehingga terdapat 20 plot percobaan. Ukuran petak percobaan yang digunakan adalah 3 m x 4 m. Adapun perlakuan yang diberikan adalah A = Aplikasi CaCl2 dan Asam Salisilat dengan interval waktu 3 hari, B = Aplikasi CaCl2 dan Asam Salisilat dengan interval waktu 6 hari, C = Aplikasi CaCl2 dan Asam Salisilat dengan interval waktu 9 hari, D = Aplikasi CaCl2 dan Asam Salisilat dengan interval waktu 12 hari, dan E = Aplikasi CaCl2 dan Asam Salisilat dengan interval waktu 15 hari.Perbedaan nilai rata-rata perlakuan diuji dengan Duncan Multiple Range Test pada taraf nyata 5 %. Grafik antar perlakuan dibandingkan dengan uji kesejajaran dan keberimpitan garis regresi (uji Chow pada taraf nyata 5 %). Hasil penelitian menunjukkan bahwa terdapat perbe-daan yang nyata yang diberikan salah satu perlakuan terhadap komponen pertumbuhan (jumlah anakan, kandungan klorofil, dan indeks luas daun), komponen hasil (jumlah malai, panjang malai, gabah isi, bobot biji per malai, dan bobot biji per tanaman). Pemberian asam salisilat dan kalsium klorida memberikan pertumbuhan dan hasil tanaman gandum terbaik pada interval 9 hari. Kata kunci : Gandum ∙ Asam salisilat ∙ Kalsium klorida

We evaluated the effect of endobacteria Bacillus subtilis (strain 10–4) as a co-inoculant for promoting plant growth and redox metabolism in two contrasting genotypes of Triticum aestivum L. (wheat): Ekada70 (drought tolerant (DT)) and Salavat Yulaev (drought susceptible (DS)) in early stages of adaptation to drought (12% PEG–6000). Results revealed that drought reduced growth and dramatically augmented oxidative stress markers, i.e., hydrogen peroxide (H2O2) and lipid peroxidation (MDA). Furthermore, the depletion of ascorbate (AsA) and glutathione (GSH), accompanied by a significant activation of ascorbate peroxidase (APX) and glutathione reductase (GR), in both stressed wheat cultivars (which was more pronounced in DS genotype) was found. B. subtilis had a protective effect on growth and antioxidant status, wherein the stabilization of AsA and GSH levels was revealed. This was accompanied by a decrease of drought-caused APX and GR activation in DS plants, while in DT plants additional antioxidant accumulation and GR activation were observed. H2O2 and MDA were considerably reduced in both drought-stressed wheat genotypes because of the application of B. subtilis. Thus, the findings suggest the key roles in B. subtilis-mediated drought tolerance in DS cv. Salavat Yulaev and DT cv. Ekada70 played are AsA and GSH, respectively; which, in both cases, resulted in reduced cell oxidative damage and improved growth in seedlings under drought.

Composition of gliadins encoded by Gli-D1 allele as well polymorphisms of Gli-D1 allele investigated in 25 wheat cultivars by using acid polyacrylamide gel electrophoresis. Electrophoregrams obtained by polyacrylamide gel electrophoresis were used for estimation variability of gliadin components and identification of gliadin blocks. Five gliadin blocks encoded by different alleles at Gli-D1 locus were apparently expressed and identified. Gliadin blocks differed according to number of components and their molecular mass. Variability of determined block components indicates that existing polymorphisms of gliadins alleles. Frequency of identified 5 alleles at Gli-D1 locus was in ratio from 4% to 52%. The highest frequency of b allele and the of g allele was found.

An experiment was carried out to study the grain growth pattern of wheat (Triticum aestivum L.) cultivars and to find out association and linear regression of spike weight and grain weight with time. Spike characters indicated that cultivar differences were significant in all the cases with a few exceptions. Linear regression and correlation coefficients revealed that the association between both spike weight and grain weight with time were highly positively significant among the cultivars but their regression coefficients were non- significant. Key Words: Grain growth, correlation, regression, wheat. DOI: 10.3329/bjar.v34i3.3960 Bangladesh J. Agril. Res. 34(3) : 351-359, September 2009
