Seven different stages waste water (WW) with ground water (control) were collected and analyzed for physiochemical as well as heavy metals properties. T8 (mixed effluent) crossed the limit of agricultural standard for almost all physiological parameters such as TDS, TSS, EC, BOD, COD affording the highest value. T8 also delivered the highest cl- and heavy metals like Cd, Ni, Cr followed by T4 (2nd wash after bath drain) < T7 (Fixing treatment water). As a consequence, these provided comparatively higher enrichment factor (EF), pollution load index (PLI) and sodium absorption ratio (SAR) to transform fresh soil into “severe” and “slightly to moderate” saline. Correlation matrix demonstrated that EF and PLI of heavy metals (except Cd, Ni) were negatively related to yield, while posi...

Three concentrations (50, 100, and 200 ppm) of silver nitrate were applied as foliar spray on female vines of three pointed gourd accessions. Application of 50 ppm silver nitrate found as effect to induce maximum proportion of hermaphrodite flowers with expanded duration irrespective of genotypes. The percentage of hermaphrodite flower induction was decreased with the increase of silver nitrate concentration. Viability of pollen grain (92.6-94.0%) in 100 ppm silver nitrate induced hermaphrodite flowers were as similar as that of normal male flowers (95.3%). Crossing among different female genotypes with pollen taken from the induced hermaphrodite flowers, produced same size of fruits of normal crossing. Seeds obtained from such crossing germinated successfully and seedlings grew vigorously as that of normal seeds. This technique seems to be useful for crossings among female plants that have suitable characters and facilitate a breeding of new variety in pointed gourd.

All the colchicine concentrations (0.05, 0.1, 0.5%) effectively led to the production of mixoploid for 48 and 72 h exposure time whereas 24 h did not response to induce mixoploid. These mixoploids (female and male) exhibit cross compatability with diploid (female and male) parents for F 1 seed generation. Interestingly, mixoploid parents (either female or male) produced a mixture of normal diploid size seeds and some abnormally large ones, almost twice normal size. Density plot and principal component analysis (PCA) of 603 seeds resulted in separation of diploid, mixoploid and tetraploid accessions involved in different ploidy crosses. To develop a method for the isolation of sexually derived triploid and tetraploid progeny from the induced mixoploids, we examined the ploidy level of F 1 populations by flow cytometry where 18.7% F 1 seedlings were confirmed as triploid and tetraploid progeny when female mixoploid crossed with male mixoploid while 16.7% triploids were isolated crossed with male diploid. These findings suggest that mixoploid female parents were the best options for developing triploid and tetraploid progeny. Overall, the results of this study provide a framework to explore the genetic basis of polyploids isolated from colchicine induced mixoploids in in vivo conditions.

The impact of textile wastewater was assessed regarding the growth, yield and nutritional qualities of Stem Amaranth. The different types of dyeing wastewater were analyzed for a wide range of parameters and compared with irrigation water quality standard. The results revealed that pH, biochemical oxygen demand, dissolved oxygen, chloride and colour of the mixed wastewater sample (D8) were exceeded the irrigation water quality standards of Department of Environment, Bangladesh while these properties of other wastewater samples were almost within the allowable limits. The growth and yield of Stem Amaranth were not strongly influenced by wastewater irrigation compared with groundwater. The yield (weight of plant) of Stem Amaranth observed in groundwater irrigated plant was...

Days to first flowering ranged from 41.00 to 51.33 days among the studied genotypes. The highest number of fruits per plant (45.27) was recorded from the genotype FP5 × WP10 followed by C41 ×TLB182 (30.90) while it was the lowest (2.27) for the genotype TLB182. The genotype C41 × VRT004 had the highest fruit weight (80.81 g) closely followed by C51 × VRT004 (79.75 g). The genotype FP5 × WP10 yielded the highest amount of fruits per plant (1.90 kg) followed by C71 × VRT004 (1.61 kg). The corresponding yield (t/ha) was also the highest (64.6 t/ha) for FP5 ×WP10 followed by C71 ×VRT004 (54.74 t/ha).

There were eight treatments comprising seven stages of textile dyeing effluents along with ground water as control treatment for irrigation purpose and okra (Lady’s finger) was used as plant material. In most of the cases ground water irrigation (T1 treatment) treated plant showed the best result regarding plant characteristics such as germination percentage (100 %), fresh (92.43 g) and dry (10.20 g) weight of plant, yield/plant (67.97 g) which were statistically similar to neutralization treatment (T5). On the contrary mixed effluent from equalization tank (T8 treatment) showed the lowest result of germination percentage (66.67 %), fresh (57.87 g) and dry (5.78 g) weight of plant and yield/plant (24.64 g). T1 treatment showed the highest amount of ascorbic acid (1.34 mg/100 g) and β-carotene (0.08 mg/100 g) and T8 treatment showed the lo...

Client was carried out at the laboratory of the Department of Horticulture, Bangabandhu Sheika .:!)bur Rahman Agricultural University, Gazipur, during winter season (November 2005 to Ap “ ■ : 006) to assess the nutritional quality of spinach varieties planted at different dates, in the shallow Red-Brown Terrace Soil. Three varieties (Pusha, Rohini and All green) and three sowing dates (November 24, December 9 and December 24) were used as treatment variables. Just after harvest, crops were thoroughly cleaned and used for biochemical analysis. Sowing dates had no significant effect on nutritional quality of spinach. The amount of water content (%), dry matter (%), ascorbic acid and P-carotene were varied significantly due to varietal differences. Among the three varieties, Rohini resulted highest water content (93.52%) and maximum dry matter (7.39%) was produced by All green variety whereas, the Pusha variety contains the highest amount of ascorbic acid (49.18 mg/lOOg) and p-ca...

Seven types of dyeing effluents have been taken as treatment variables, and their effects on the germination of country beans at the early growth stage compared The treatment of neutralized effluent water (D5) enhanced the germination percentage remarkably (100%) as well as statistically identical with the result of underground water (D1) whereas the treatments of effluent from 2nd wash after Bath (D4) and mixed effluent from ETP showed poor germination (73.33%). Second wash after scouring and bleaching treatment (D2) showed a good result. All results have been considered on the basis of germination energy, relative germination rate, effluents injury rate and germination velocity. Neutralized effluent water (D5) performed better at the seedling growth period of country bean plants. But D4 treatment performed very poorly among ...
