Different methods for beech seed quality testing

This paper presents three different methods for beech seed quality testing. The aim of this study is to determine the correlation between the electrical conductivity test, tetrazolium test and hydrogen peroxide treatment. The seed was collected in 12 different seed stands in Serbia that are commonly used for nursery production. The seed sample used for testing was randomly taken from the total amount of the collected seed. The analysis of the obtained results included the calculation of the Pearson correlation coefficient in the statistical software package "Statistica 7". The correlation was determined between the recorded results of the seed weight and the electrical conductivity; the seed weight and the tetrazolium test; the seed weight and the hydrogen peroxide treatment; the electrical conductivity and the tetrazolium test; the electrical conductivity and the hydrogen peroxide treatment; the tetrazolium test and the hydrogen peroxide treatment. Based on the conducted researches it can be concluded that the standardization of the electrical conductivity test using the tetrazolium test and hydrogen peroxide treatment could contribute to a more quality and more comprehensive determination of the beech seed quality for commercial purposes.

AbstractThe aim of the study was to determine the effect of mechanical harvest on the seed quality of yellow lupin. Two effects were studied: the cultivar of yellow lupin (the indeterminate cultivar - Mister and the determinate cultivar - Perkoz) and harvest methods: hand-picked plants with manual shelling of seeds as a control and mechanical shelling with a plot harvester. In comparison with manual shelling of seeds, the mechanical harvest reduced the seed germination and increased the number of abnormal seeds both cultivars. Determinate cultivar was more sensitive, because the loss of its quality was higher (germination of 10%) than indeterminate cultivar (6%). Perkoz had also higher electrical conductivity, with the mean value of 34.3 μS × cm−1× g−1. Manual shelled seeds were characterized by a significantly lower leakage of exudates (24.9 μS × cm−1× g−1), and hence, it exhibited greater vigour than mechanical harvested seeds. Most relations of Pearson correlation coefficient between vigour tests and germination were strong or practically functional.

Storage Containers

An experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during April 2013 to June 2013 to study the effect of three storage containers (tin container, polythene bag and cloth bag); and five storage periods (0, 15, 30, 45, and 60 days) on the seed quality of soybean. The experiment was laid out in Completely Randomized Design (CRD) with four replications. The soybean seeds stored in tin container showed maximum germination capacity with high germination index, highest seedling growth, seedling dry weight per plant and vigour index. The seeds stored in cloth bag had the lowest seed quality during the testing period. The highest 1000-seed weight, moisture content, electrical conductivity, abnormal seedlings and number of dead seeds were recorded in cloth bag; where the equivalent lowest values were recorded in tin container. The moisture content, 1000-seed weight, electrical conductivity, number of abnormal seedlings and dead seeds were increased with the longer period of storage. In addition, germination index, seedling growth, dry weight per plant of soybean seedling, and vigor index decreased with the increase in storage period. Among the three containers, tin container was the best and the cloth bag was the worst storage container for soybean seed storage for long period.

Yield And Quality

Freshly harvested seeds of chilli variety Anugraha were treated with halogens namely Calcium oxy chloride (CaOCl2) and Iodine crystal (I2) indirectly through a carrier Calcium carbonate (CaCO3). The treatments included Control (Untreated), CaOCl2 + CaCO3 (2g each/kg seed), CaOCl2 + CaCO3 (4g each/kg seed), Iodine crystal + CaCO3 (50mg each/kg seed) and Iodine crystal + CaCO3 (100mg each/kg seed). Seed treatment with CaOCl2 + CaCO3 @2g each/kg seed registered significantly higher values for fruits per plant, fruit weight, seed yield per plant and hundred seed weight followed by CaOCl2 + CaCO3 @4g each/kg seed. The treatments, CaOCl2 + CaCO3 @2 g each/kg seed and Iodine crystal + CaCO3 @100mg each/kg seed performed superior in seed quality with higher seedling vigour and lower electrical conductivity of seed leachates over other treatments, while untreated control recorded least seedling vigour indices and highest electrical conductivity.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.
