An experiment was conducted to find out the suitable plant growth regulator(s) for inducing parthenocarpic fruit in kakrol (Momordica dioicia Roxb). Four plant growth regulators, viz. NAA and 2, 4-D (Auxins), Fulmet (Cytokinine) and GA3 (Gibberellic acid) were sprayed at three stages (a day before anthesis, at anthesis, a day after anthesis). Out of four growth regulators 2, 4-D and fulmet induced parthenocarpic fruit development. Fruit set percent, final fruit weight, fruit length and fruit diameter varied significantly with different treatment combinations. 2, 4-D at 50 ppm when applied at anthesis showed better performance in inducing parthenocarpy.DOI: http://dx.doi.org/10.3329/bjpbg.v20i2.17030
The experiment was carried out in a non replicated design with 40 accessions of brinjal (Solanum melongena L.) at Plant Genetic Resources Centre (PGRC), BARI Gazipur to characterize and study the genetic diversity and identify the useful traits. Each accession of nine plants was grownin a 3 X 2 m size plot. The accessions were collected from 16 districts of Bangladesh. Two to four classes were found for plant growth habit, leaf blade lobing, leaf prickles, flower colour, fruit shape, fruit apex shape and fruit colour distribution. The accessions exhibited 64% straight, 13% both slightly curved and curved, and 10% snaked shaped edible fruit along with 55% purple and 45% green fruit. Fruit length of accessions ranged from 5 to 31.23 cm, breadth 2.4 to 10.6 cm, weight 13 to 95.2 g and 3 to 30 fruits per plant. The accessions were grouped into five clusters. The inter and intra cluster distances ranged from 4.01 to 8.32 and 0.94 to 1.36, respectively. Accessions collected from the same districts felt into different clusters. The results obtained by D2 analysis were also confirmed by canonical analysis. Crosses BD-7327 (Rangpur) of cluster II with BD-9954 (Chittagong) of Cluster-III and BD-7319 (Panchagarh) of Cluster-I with BD-11732 (Bandarban) of cluster V, could be performed for obtaining wider variability in the segregating generations. The breeders could use the selected accessions for varietal improvement of brinjal.Bangladesh J. Agril. Res. 43(3): 499-512, September 2018
An investigation was carried out to identify the extent of genetic divergence of seventeen vegetable pea genotypes at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh. Genetic divergence was estimated using D2 and principal component analysis. The genotypes under study fell into 4 clusters. The distribution pattern indicated that the maximum numbers of genotypes (6) were included in cluster II and cluster III and the minimum number in cluster IV (1). The inter-cluster distance was higher than the intra-cluster distance which indicated wider genetic diversity among the accessions of different groups. The highest inter-cluster distance was observed between II and IV. The lowest inter-cluster distance was observed between clusters II and III suggesting a close relationship among the genotypes of these two clusters. The highest intra-cluster distance was observed for the cluster II. The positive values of vector I and vector II for plant height, 50% flowering and non-reducing sugar indicated that these characters had the highest contribution towards the divergence among the pea genotypes. The genotypes of vegetable pea from cluster II and cluster IV maybe selected as parents in future hybridization program.DOI: http://dx.doi.org/10.3329/bjpbg.v26i1.19982

Background: Spontaneous intracranial haemorrhage (ICH) is defined as intraparenchymal bleeding in the absence of trauma or surgery. Spontaneous ICH is most disabling and deadly type of stroke. Meteorologic factors and seasons on the incidence of spontaneous ICH with ambiguous results. Objectives: To determine whether different seasons had any relationship with the rate of primary intracerebral hemorrhage. Methods: Total of 209 patients were diagnosed as spontaneous ICH and they have been first time reported & admitted in Combined Military Hospital (CMH) Dhaka, between Jan 2017 and December 2018. Males were 146(69.85%), females were 63(30.15%) and were aged between 18 and 95 years old. Diagnosis was based on history, clinical examination and non-contrast Computed Tomography(CT) scan of brain. Results: 209 admitted patients in CMH Dhaka from Jan 2017- Dec 2018 are included in our study who full-fill the criteria. Intracerebral haemorrhage rate among age group less than 55years old being 55(26.31%) and 55 years and above 154(73.69%).There were a significant relationship between different seasons and intracerebral haemorrhage. Intracerebral haemorrhage incidence in winter season 61(29.18%) and late autumn 19(9.09%), out of 209 patients. Among them hypertensive patients were 137(65.55%) and non-hypertensive patient 72(34.45%), 170 (81.33%) were nondiabetic & 39(18.66%) diabetic of total 209 patients.Out of 61 patients in winter; 54 (88.52%) hypertensive patients had large sized haemorrhage. Conclusion: The highest rate of intracerebral haemorrhage during December-January. There is a seasonal variation in patient’s age, incidence among hypertensive patients, size of hemorrhage and more in number in winter season. Bang. J Neurosurgery 2020; 9(2): 130-134
