In vitro propagation of red rose [Rosa pisiformis (Christ.) D. Sosn.] has great importance in rapid proliferation of species with medicinal features and in culture of healthy plants free from deseases. After a succesfully pre-sterilization procedure, experiments were maintained by two-phase: multiplication phase and rooting of microshoots phase. Micropropagation of Rose was improved, using its nodal segments under different combination of BAP (0, 1.0, 2.0, 0.6 mg/l), NAA (0, 0.1, 0.2, 0.01 mg/l) on Driver and Kuniyuki (DKW) and MS medium in multiplication phase and using distinct compositions of IBA (0, 1.0, 3.0, 5.0 mg/l) and DKW medium in rooting phase. The maximum number of shoots/per plant (22.6) with the highest number of leaves (222.6) were obtained in DKW medium supplemented with 0.6 mgl-1 BAP and 0.01 mg/l NAA. The leaf explants were also used to occur callus in MS with different combinations of BAP and NAA. Good callus formation was obtained with 1:2 ratio of BAP:NAA combination in MS medium. Furthermore, the highest root induction (100%) was achieved in DKW medium consisting of 1 mg/l IBA. The rooted plantlets were transferred to the field after acclimatized in greenfield conditions. The present investigation presents an in vitro protocol for R. pisiformis. Bangladesh J. Bot. 52(4): 949-958, 2023 (December)
红玫瑰[Rosa pisiformis (Christ.) D. Sosn.]的体外繁殖对于快速增殖具有药用价值的品种和培养无病虫害的健康植株具有重要意义。 经过成功的预灭菌程序后，实验分两个阶段进行：繁殖阶段和小芽生根阶段。在增殖阶段，使用不同组合的 BAP（0、1.0、2.0、0.6 毫克/升）、NAA（0、0.1、0.2、0.01 毫克/升）在 Driver 和 Kuniyuki（DKW）和 MS 培养基上进行微繁殖，在生根阶段，使用不同组合的 IBA（0、1.0、3.0、5.0 毫克/升）和 DKW 培养基进行微繁殖。 在添加了 0.6 毫克/升 BAP 和 0.01 毫克/升 NAA 的 DKW 培养基中，每株获得的芽数最多（22.6），叶片数最多（222.6）。叶片外植体也被用来在添加了不同 BAP 和 NAA 组合的 MS 中形成胼胝体。在 MS 培养基中，BAP:NAA 的组合比例为 1:2，胼胝体形成效果良好。此外，在含有 1 毫克/升 IBA 的 DKW 培养基中，根诱导率最高（100%）。生根的小植株在绿地条件下适应后被转移到田间。本研究提出了一种 R. pisiformis 的离体培养方案。孟加拉国植物学杂志》（Bangladesh J.

The karyomorphological features of Holarrhena antidysenterica (Roxb. ex Fleming) Wall. through the application of differential staining techniques (using orcein, CMA, and DAPI) were studied. After applying orcein staining, the interphase nuclei of this species exhibited a ‘simple chromocenter type’ with numerous small heterochromatin blocks and the prophase chromosomes were ‘interstitial type’. The karyotype analysis revealed that this species possesses diploid chromosome number of 2n = 22, with all metacentric chromosomes. The total length of the chromosome complement in the diploid set was 29.91 μm. A total of four CMA-positive bands were observed in this species whereas seven bands were found after DAPI-staining. Heteromorphicity was observed in the DAPI stained metaphase stage indicating the probable occurrences of chromosomal aberrations such as deletion and inversion. The karyotype profile of H. antidysenterica obtained from orcein and fluorescent banding was determined for the first time in Bangladesh. Bangladesh J. Bot. 52(4): 1085-1089, 2023 (December)
通过应用不同的染色技术（使用orcein、CMA和DAPI），研究了Holarrhena antidysenterica (Roxb. ex Fleming) Wall.的核形态学特征。在使用橙皮苷染色后，该物种的间期细胞核表现为 "简单染色中心型"，其中有许多小的异染色质块，而前期染色体则为 "间隙型"。核型分析表明，该物种的二倍体染色体数为 2n = 22，全部为偏心染色体。二倍体染色体互补体的总长度为 29.91 μm。该物种共观察到四条 CMA 阳性条带，而 DAPI 染色后则发现七条条带。在 DAPI 染色的移行期观察到异形，表明可能存在染色体畸变，如缺失和倒位。在孟加拉国，首次确定了通过橙皮苷和荧光带染色获得的 H. antidysenterica 的核型特征。孟加拉国 J.

Black rot disease caused by bacterium Xanthomonas campestris pv. campestris has been identified as major cause for low cabbage yields. The present study was conducted to evaluate the efficacy of various antibiotics and bioagents for controlling black rot disease and also their effect on extracellular polysaccharide secretion (EPS) of Xanthomonas campestris pv. campestris. Under in vitro conditions, bacterial proliferation and EPS production were examined on yeast peptone agar medium containing sucrose or trehalose with or without antibiotics. Number of Xanthomonas campestris pv. campestris on yeast peptone agar medium with Validamycin-A was less as compared to control. Extracellular polysaccharide secretion (EPS) was also inhibited on yeast peptone agar medium with antibiotic Validamycin-A. In vivo, disease intensity was recorded minimum in seed treatment + root dipping + foliar spray with Validamycin-A @ 500 µg/ml followed by seed treatment with Validamycin-A @ 500 µg/ml in comparison to control. Similarly, 45.61% higher cabbage yield was recorded in seed treatment + root dipping + foliar spray with Validamycin-A @ 500 as compared to untreated control. However, the antibiotic Validamycin-A which was found effective can be recommended to manage the disease. Bangladesh J. Bot. 52(4): 965-970, 2023 (December)

The bacterial strain TG6 was screened from the soil of a muskmelon greenhouse, which could effectively inhibit the growth of Sphaerotheca fuliginea, Fusarium oxysporum, Phytophthora melonis and Pseudoperonospora cubensis of muskmelons. TG6 was identified as Bacillus subtilis through morphological, physiological, biochemical and molecular studies. Taking TG6 as the original strain, TG67 and TG69 were obtained by He-Ne laser mutagenesis. The microbial compound antagonist strain TG67 and TG69 was prepared in the ratio of 1:1 and applied to the biological control of greenhouse melon. Muskmelon field experiments showed that the bactericide could effectively control the occurrence of various diseases of muskmelon in greenhouse. Bangladesh J. Bot. 52(4): 1047-1053, 2023 (December)

The present investigation was intended to assess the extent of genetic diversity present among the selected genotypes of Oryza sativa (including TGMS lines) using SSR markers. The SSR markers used for the study gave average Polymorphism Information Content (PIC) value of 0.551. The primer RM 9 followed by RM 536 has given maximum PIC value and the primer RM 29 gave the minimum. It was inferred that the primers RM 9 and RM 536 had been the better choices in this study. The lines, TS09 24 and TS09 26 were in the same cluster as they derived from the same parents. The TGMS lines TS 29 and TNAU 27S are in separate cluster from other parents indicating that these lines are highly diversified and their crosses can give improved cultivars. Bangladesh J.

Genotype-environment interaction is the norm of reciprocal action that determines the relationship between gene and environmental factors. Gene and environment interaction takes place when different environments affect the genotypes and vice versa. The investigation portrays the interaction between genes and environments of yield contributing characteristics of eleven genotypes of field mustard. Three seeding-time environments, viz., early, late, and very late of eleven mustard genotypes were laid out with three replications in a randomized complete block design. Among the three environments, which one was favorable and which was not was determined by their significant differences through a combined analysis of variance. The IPCA 1 (first interaction principal component axis) score of genotypes in the AMMI (additive main effects and multiplicative interaction analysis) of G×E interactions was estimated as an indication of the ability to respond to the environments and the performance with changing environments of the genotypes. Considering all the scores, Sonali Sharisha (SS-75), and BINA Sharisha-10 were found to be highly stable genotypes, while among the three environments, the environment-1 (early sowing) was found the best sowing time for raising and harvesting a good mustard crop.

To understand the changes in grain internal structure and nutrients during maize filling, Jingkenuo 2000 (waxy corn), Chaosweet 2000 (sweet corn), and Zhengdan 958 (common corn) were used as test materials. This study observed the internal structure of the corn grain and measured the change in nutritional quality during the filling period. Throughout the determination stage, the starch granules did not fill the whole endosperm cell in Chaosweet 2000, and the cell wall was clearly visible. By contrast, the starch granules filled the whole endosperm cell in Jingkenuo 2000 and Zhengdan 958. The protein content in Chaosweet 2000 was significantly (P<0.05) higher than those in Jingkenuo 2000 and Zhengdan 958. With the extension of post-pollination time, the content of soluble sugar decreased significantly (P<0.05) in Chaosweet 2000, Jingkenuo 2000, and Zhengdan 958. Bangladesh J.

In the present study effects of organic substance and plant growth regulators on yield attributes and quality of guava cv. Lucknow 49 were conducted during 2021-2022. Results indicated that foliar application of novel organic liquid fertilizer (40 ml/l) gave higher yield parameters viz. number of flowers per branch, fruit set, weight per fruit, fruit volume, fruit diameter, fruit length, pulp weight per fruit, number of fruits per plant, fruit yield (kg/plant) during both the years and in pooled data. In quality parameters, higher chlorophyll content and pulp: seed ratio were recorded with novel organic liquid fertilizer (40 ml/l) during both the years and in pooled data. However, organic substance and plant growth regulators treatments showed non-significant effect on total seed weight per fruit in both the years as well as in pooled data. Bangladesh J.

This study aims to optimise the condition for seed germination and seedling emergence of Sesbania cannabina (Retz.) Poir. for a phytoremediation study. In this experiment, seed germination was carried out using two growth media: Murashige and Skoog basal medium (MS); and Whatman Grad 1 filter paper (FP), using the top of media or top of the paper method under three different photoperiods. Seeds were pre-treated for different lengths of time with various concentrations of hydrogen peroxide (H2O2) (v/v) multiple hot water treatments. Results showed that seeds pre-treated with H2O2 (6% v/v) for 5 minutes and primed with 65°C water for 5 minutes were considered as the ideal pre-treatment condition. Different photoperiods and media used in germination in this experiment do not significantly affect seed germination. The optimum condition for seed germination at 27.5 °C ± 2.5°C and relative humidity of ~ 75% for 5 days. Seed emergence in soil and compost was significantly affected by the burial depth and bulk density of the media, with the highest (98%±1) seed emergence observed at 1 cm depth for soil and compost, and decreasing with increased burial depth. This ideal condition will help in further studies related to plant growth and phytoremediation of S. cannabina. Bangladesh J. Bot. 52(4): 1015-1023, 2023 (December)
