Osmotic adjustment is one of the important mechanisms to adapt to drought and it is the only one which is activated under any level of water stress in the plant cells. Grapevine pollen grains response was tested to osmotic stress in fourteen genotypes, initiated by immersion in 55% or 65% polyethylene glycol solutions without and with addition of potassium chloride, to estimate the expressions of osmotic adjustment. The pollen grain test found differences both in the measurements of projected area cytoplasm and expressions of osmotic adjustment present in the cells. Italian Riesling increased pollen grains cytoplasm in PEG solutions with added KCl much more than other genotypes and had the high values for both expressions of induced and overall osmotic adjustment. The results obtained for expression of induced osmotic adjustment underlined the high K+ accumulation capacity of ‘Italian Riesling’, ‘Burgund mare’ 86 Şt., ‘Muscat d’Adda’ 22 Şt., ‘Muscat Ottonel’ 16 Şt., ‘Pinot gris’ 14 Şt. and ‘Argessis’. The lack of correlation between expressions of induced and intrinsic osmotic adjustment indicated that induced osmotic adjustment expressed by K+ might use different mechanisms that are activated at the time of water stress with different levels of solute accumulation. Because the accumulation of K+ in the cells is important in all developmental stages and, in grape yield and quality, pollen responses to induced osmotic adjustment expressed by K+ could be used as a screening method, for establishing the level of drought sensitivity in the grape varieties under water stress.

Urban forests are an essential component of urban areas as they provide many environmental and social services that contribute to the quality of life in cities. Urban forests in most cities of Nigeria are gradually becoming bitty as a result of urbanization activities, thereby posing adverse effects. In this study, we assessed the changes in the urban forests cover under the influence of different human settlement (HS) extents across the urban area of Ibadan city using remotely sensed data. The pattern of change(s) in the urban forests cover over 20 years were examined by analysing and manipulating Landsat and Sentinel-2 datasets using Google Earth Engine, ArcGIS 10.1, and Erdas 2014 software. The extents of human settlement (for the year 2000, 2005, 2010, 2015, and 2020) were extracted (from Landsat datasets), analysed, and mapped to evaluate the status of the urban forests cover under different human settlement extents. The result reveals a substantial land cover changes within the urban area of Ibadan. The urban forest cover decreased from 24.14% to 7.99%. Also, there is a significant decrease in the urban forests cover as a result of a substantial increase in human settlement extent (102,806 to 122,572 pixels). The study provides an opportunity to map the status of urban forest cover and extents of HS in a developing city using remotely sensed data and applications of GIS tools.

Cornelian cherry (Cornus mas L) is one of the most valuable fruit shrubs of the Cornaceae family, and therefore the vegetative propagation of the valuable selections is necessary because the material obtained must be used for the future. 4 genotypes were studied (2 perspective selections: H1 and H3 and two cultivars used as a control: ‘De Bucovăț’ (B) and ‘De Orhei’ (O) and propagated by grafting (the grafting method used was improved copulation. Biometric observations were focused on diameter below the point of graft (mm), diameter at the graft point (mm), diameter above the graft point (mm), height of graft (cm), number of anticipated, average length of the anticipated (cm), the sum of the anticipated length (cm), the growth increase (cm). Based on the results obtained, it can be concluded that the grafting method, enhanced copulation, within vegetative propagation, can be successfully used in the production of cornelian cherry planting material next to the other known methods; the growth of the anticipated shoots on plant could cause the appearance of flowering buds and implicitly earliness in fruit-setting.

Anatomical and histochemical studies of ovary and caryopsis of sorghum reveal the importance of the chalazal complex in transporting nutrients from maternal sources to the filial diploid embryo and triploid endosperm. The presence of starch, protein, lipid, Ca, K, Mg, and Fe in various tissues at different stages of development can be revealed by a variety of histochemical techniques. Vascular supply ends at the base of the ovary and transport occurs through vascular parenchyma, pigment strand and nucellar projection where symplastic continuity is broken. Nutrients unloaded into an apoplastic placental sac then enter the endosperm and embryo through the aleurone transfer cells. The later possess characteristic wall ingrowth. The single layer of aleurone surrounding the endosperm may also help in transport during later stages of grain-filling. Grain-filling in C4 sorghum is compared with other C4 and C3 grasses showing the variety of strategies evolved to transport nutrients into filial tissues. Standardization of terminologies to describe the tissues of the crease region will help in further research and communication.

This study evaluated the influence of human chorionic gonadotropin on hormonal and haematological profile of postpubertal male albino rats exposed to chronic oral administration of alcohol. Twenty-four mature male albino rats were assigned to four groups (n=6). Group A was the control, given distilled water, Group B was given 30% ethanol (8 ml/kg) orally 3 times a week, Group C was given human chorionic gonadotropin (HcG) (50 IU/kg) subcutaneously 3 times a week and Group D was given HcG (50 IU/kg) subcutaneously + 30% ethanol (8 ml/kg) orally 3 times a week. The study was for 10 weeks, and hormonal profile and haematology were determined. The follicle stimulating hormone of Group B decreased significantly (P

Okra growth and yield are adversely affected by drought at different growth stages. This is aggravated by poor soil fertility. In this study, the roles of compost applied at 0, 5 and 10 t/ha on the tolerance and morpho-physiological response of okra (NHAe 47-4) exposed to varying levels of water stress (25%, 50%, 75% and 100% field capacity, FC), at different growth stages (vegetative, reproductive and vegetative-reproductive stages) for ten days duration were assessed. Data were collected on okra growth and yield, leaf relative water content (LRWC), leaf photosynthetic pigments (LPG) and proline accumulation. Results showed that drought stress reduced LRWC, LPG, growth and yield of Okra. This reduction was more evident in okra plants exposed to severe stress for 10 days and at the reproductive stage. Soil amendment with compost however, had cushioning effect on drought stressed okra. Compared to control, it increased the LRWC, LPG, growth and yield of okra. The ameliorative roles of compost were however, dependent on stress intensity, compost dosage, okra growth stage and stress duration. Though, okra plants stressed at 25% FC were more affected by drought stress, but compared to the un-amended soil, those grown on amended soil were more tolerant. Higher compost rate was superior to lower rates. Whereas, higher proline accumulation was recorded in plant exposed to 25% field capacity without amendment, proline accumulation was reduced in the plants grown on compost amended soil and exposed to drought which was an indication of stress reduction. Generally, okra stressed at vegetative growth stage only was able to recover rapidly and had better yield compared to those stressed at reproductive growth stage. It is concluded that addition of compost to soil could reduce the drought stress effect on okra.

The present study attempts to investigate the phenological changes of herbaceous plant species in early snowmelt microsite and late snowmelt microsite in treeline ecotone (3200-3300 m asl) at Tungnath, western Himalaya. Four sites, each with two microsites (early snowmelt: ES and late snowmelt: LS) were selected and within each microsite, 3 quadrats (1x1m each) were permanently laid and studied for phenology. Eighty-six species were recorded, of which the proportion of perennial forbs, hemicryptophytes and natives was 90, 84 and 70%, respectively. The early phenophase was noticed in the majority of species in ES microsite than that of LS microsite and the timing of different phenophases varied among microsites. The vegetative phase peaked July (75.6%), while flowering, fruiting and seed maturation phases peaked in August (72.1% and 23.3%, respectively) and 71% species attained the senescence during September. This indicates that species might adapt to the different adaptation to a warming climate. Immediately after the snowmelt 10 species were observed in flowering, while 11 species were in the bud development phase. Comparing 13 common species of the present study with those of past in same or similar study areas indicates that timing and duration of vegetative and flowering phenophase (77% and 69%, respectively) have advanced and lengthened, while fruiting and seed maturation have shortened. Furthermore, phenophase initiation has advanced for flowering (69% species), fruiting (46% species) and senescence (38% species) phases. It seems that the early snowmelt influences spring phenology of herb species on the microsite level and may continue to influence the overall phenology of species for the whole growing season in timberline.

To understand the phylogenetic status of Ariidae, Bagridae and Plotosidae catfishes, this study was planned using the barcode gene, cytochrome oxidase I (COI). Totally 71 species were used in phylogenetic reconstructions under maximum parsimony, maximum likelihood and Bayesian inference criteria. The one-way ANOVA showed that the three catfish families are significantly different (F= 19.79, d.f. = 3; 116, P< 0.0001 (Plotosidae); F= 44.21, d.f.= 3; 986, P< 0.0001 (Ariidae); F= 24.83, d.f.= 3; 1322, P< 0.0001 (Bagridae). In MP, ML and BI based phylogenetic tree of Ariidae, Plicofollis genus displayed as a monophyletic group with higher bootstrap and posterior probability values for all the species except two species of Neoarius, which intervened separating P. polystaphylodon. In the phylogenetic tree of Plotoside, Plotosus genus displayed as monophyletic group with higher bootstrap and posterior probability values for all the eight species. In the case of Bagridae phylogeentic tree, Mystus genus displayed as a monophyletic group with higher bootstrap and posterior probability values for all the species except Mystus montanus forming a distant and distinct clade whereas Mystus tengara collides into monophyletic clade when Neotropius genuswas removed. By this study we could establish a phylogenetic hypothesis for all the 36 catfish families and examine the monophyly status of the subfamilies and genera.
