Abstract Background Mango is an important cash crop greatly contributing for food security of fruit growers in northwestern parts of Tigray region, northern Ethiopia. However, information was critically lacking with respect to germination and growth response of mango rootstock to varying compositions of growing media in the region. Thus, an experiment was conducted during 2018 to evaluate germination and seedling growth response of mango cultivars to different combinations of nursery potting media in a net house at Indasellassie. Seeds of Local, Dodo and Keitt cultivars of mango were sown in full top soil (M1); top soil: sawdust: sand (3:2:1)(M2); top soil: FYM (Farmyard manure): sand (3:2:1)(M3); and top soil: FYM: sawdust: (3:2:1)(M4). Randomized complete block design in a factorial arrangement with three replications were used. Data on germination and growth parameters were collected and analyzed using GenStat software. Results The findings of the experiment revealed that mango cultivar had significantly affected most of the germination and growth parameters except shoot number. Moreover, potting media affected most of the parameters except days to germination, germination percentage, stem diameter, root number, and shoot number. Interaction effects of cultivar and growing media significantly affected all parameters except internode length, shoot number and stem diameter. Accordingly, interactions of local mango cultivar and M3 media combination gave the highest for most of the parameters with the order of M3 = M1 = M4 > M2 for germination percentage, M3 = M1 > M4 = M2 for plant height, M3 > M1 > M2 = M4 for leaf number, M3 > M1 > M4 > M2 for leaf area, M3 = M1 > M2 = M4 for stem diameter, M3 = M1 > M2 > M4 for root number, M3 > M2 > M1 = M4 for root length, M3 > M1 > M2 = M4 for fresh weight, M3 > M1 = M2 = M4 for dry weight and Vigorosity II of mango. Conclusion Considering better mango performance on seed germination, seedling growth and establishment in the study area, mango growers should use Local mango cultivar with soil potting media combinations of top soil: FYM: sand in the ratio of 3:2:1 for improving productivity and food security.

This study investigated the effects of potting media on seed germination and early seedling growth of Pterocarpus erinaceus Poir at the Forestry Nursery in Jos, Nigeria. Using Completely Randomized Design (CRD) with three replicates, laboratory-tested soil samples, top soil, sharp sand, sharp sand + top soil, sharp sand + top soil + cow dung and sharp sand + top soil + poultry droppings were used in various combinations to assess the growth parameters of P. erinaceus (germination percentage, emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Descriptive and inferential statistics were employed to analyze collected data. Result indicated that sharp sand + top soil + poultry droppings had the highest nitrogen concentration (2.19%), sharp sand + top soil + cow dung (2.07%), sharp sand + top soil (1.50%), top soil (0.72%) and Sharp sand (0.38%). Potting media with poultry droppings recorded an overall higher percentage germination of 42.9% by the end of the germination period. Analysis of variance (ANOVA) of collected data on combined soil aggregate on growth parameters indicated a significant (p<0.05) difference in plant height, number of leaves, leaf length and stem diameter. Potting with poultry dropping gave the best potting media growth results when compared to other treatments that enhanced seed germination and seedling growth of P. erinaceus. This superior observation of the poultry droppings incorporated potting mixtures over the cow dung provides an outstanding potentials to enhance P. erinaceus plantation establishment. Consequently, recommended for raising seedlings in the nursery as well as ensuring sustainable management.

Rhizosphere Sample

The aims of this research are to apply Senaru forest  rhizosphere on Kabupaten Lombok Barat West Nusa Tenggara as Mycorrhiza inoculants for Gyrinops versteegii germination and growth. Rhizosphere sample was taken from ten sampling spot on Senaru forest between Latitude: 08o18.808’ S – 08o19.174’ S and Longitude: 116o24.138’ E – 116o24.181’E. This study employed Factorial Experiment Design with 2 Factor including: Medium Composition (M) and Mychorizza Inoculant (I). There were 5 media composition: M1 (sand), M2 (soil:sand = 1:2), M3 (soil:sand = 1:1), M4 (soil:sand = 2:1), M5 (soil). There were 2 types of Inoculation: I1 (without inoculant) and I2 (innoculant from senaru Rhizosphere). Growth parameters observed in this study were: germination percentage, stem length, stem diameter and root colonization. Germination percentage of G. versteegii seeds in all growth media are below 60 % which could be classified as low germination rate. Also germination from media without rhizosphere is higher than germination from media with rhizosphere. On the other hand, G. versteegii growth on rhizosphere media is slightly higher than growth of G. versteegii on media without rhizosphere based on stem diameter and length measurement. It tends that medium composition with higher sand proportion tended to gives better germination and growth rate of G. verteegii. Myorrhiza colonization on G. versteegii root was higher in media with rhizosphere addition. It could be concluded that Application of Senaru rhizosphere containing Mycorrhiza increases G. versteegii growth but not its germination percentage. This research enrich knowledge in biological science about asociation of mycorrhiza with G. versteegii especially on its growth and germination

Germination Indices

The study aimed to evaluate the use of germination indices as a screening tool for salinity tolerance during germination and early seedling growth of pepper cultivars, and to distinguish the potential for genetic responses to salt tolerance. In the study, the seeds of seven pepper cultivars were germinated at increasing NaCl levels of 5, 10, 15 and 20 dS/m and distilled water as the control treatment for 14 days. Germination percentage (GP), mean germination time (MGT), germination index (GI), germination stress tolerance index (GSTI), seedling length (SL), seedling fresh weight (SFW) and vigor index (VI) were investigated. Results showed that germination percentage decreased with increasing NaCl levels while the highest germination percentage at 20 dS/m was 92% in BT Burdem with no significant reduction. Seedling growth of pepper cultivars was severely inhibited by increasing salinity stress. SFW was depressed depending on reduction in SL due to increasing NaCl. BT-Burli and BT İnce Sivri were the most tolerant cultivars to NaCl and they were used for genetic resources towards salinity. Seedling growth was much more sensitive to salinity than germination because of the highest percent reduction in seedling growth parameters. Among the parameters, GSTI gave the highest significant correlation coefficient with SL and SFW; indicating that it would be useful for estimating seedling growth. It was concluded that genotypic variation was observed among pepper cultivars for salinity tolerance and GSTI could be used for a predictor for salinity tolerance.

This study investigated the effect of sowing media on the seed germination and subsequent seedling growth of Senna fistula L. Treatments were T1 (Top soil), T2 (River sand), T3 (Grinded coconut husk) and T4 (weathered sawdust), replicated two times for seed germination. The treatments were arranged in a Completely Randomized Design (CRD) and the data generated was subjected to analysis of variance (ANOVA) at 5% level of significance, while mean separation where appropriate was done using Least Significant Difference (LSD). The different sowing media used had positive effect on the seed emergence, the seeds planted in river sand had the highest emergence percentage of 70%. The different sowing media used did not have any significant effect on the vegetative growth parameters, statistically, they had same effect on the parameters measured. Nonetheless, seedlings from river sand produced highest number of leave (20.4), seedlings from topsoil produced highest plant height and largest leaf area of l0.62 cm and 37.l4 cm2 respectively. The seedlings from weathered sawdust produced the highest stem diameter of 0.79 mm, while seedlings from grinded coconut husk had lowest values for all the growth parameters measured. Therefore, it is recommended that river sand or weathered sawdust can be used to propagate Senna fistula seeds.

AbstractThis study was carried out to determine effects of salinity on germination and seedling development of commercially important common bean genotypes in Cameroon. The seeds of eight genotypes were used for both trials. The germination experiments were carried out on petri dishes in the laboratory while early growth trials continued in plastic pots in the screenhouse. Both stages were setup using a randomized complete block design with three replications. Germination and early growth trials of the different genotypes were studied using distilled water as control or osmotic potentials of 50, 100, 150 and 200mM NaCl to study the effects of salinity on germination and seedling growth characteristics. Leaf concentrations of Na+ and K+ were determined. At the germination level, germination percentage, germination index and the coefficient of velocity of germination decreased with increasing salinity while the mean germination time and time to 50% germination increased with increasing level of salt. All the growth variables decreased with increasing salinity with the exception of the root length which was not affected by salinity. It was observed that increasing salinity induced a significant increase in leaf Na+ and substantial reduction in the accumulation of K+ in the leaves. For ions accumulation, germination variables and growth parameters, significant differences at 0.001 probability levels were found among salinity treatments, common bean genotypes and most of their interactions. Significant correlations were found between all germination variables and between most growth parameters. From the effect of salt application, the common bean genotypes namely KEBCB049, KEB-CB053 and Mac-33 were the most tolerant while KEB-CB055 and KEB-CB050 were the most sensitive. The results confirm that there is genotypic variation in salinity tolerance and that the most tolerant genotypes should be further explored in selection programs, with the aim that they should be promoted for cultivation in tropical zones affected by salinity.

Allelopathic effects of lantana (Lantana camaraL. ♯3LANCA) residues (root, shoot), foliar leachates, and the soil (where lantana was grown) on milkweedvine (Morrenia odorataLindl. ♯3MONOD) seed germination and growth over a 30-day period were examined. Foliar leachates or the soil collected from the field where lantana had been growing had no effect on the final germination percentage or the seedling growth of milkweedvine. Incorporation of dried lantana shoot or root material into soil had no effect on the final percentage germination but caused significant reductions in milkweedvine growth over a 30-day test period. Roots were more inhibitory than shoots. Fifty percent of milkweedvine seedlings died within 15 days after germination at 1% (w/w) dried lantana root incorporation into the soil, and higher concentrations increased seedling death. Lantana roots incorporated into the soil produced foliar symptoms such as wilting and desiccation, whereas lantana shoots incorporated into the soil produced yellowing of the foliage of milkweedvine. Allelopathic activity of lantana residues was still strong even after decomposition of lantana residues for 4 weeks prior to the planting of milkweedvine seeds.

The response in growth and development of seedlings of Dialium guineense to different potting media was studied in the screen house. Five potting media: River sand (Rs), Top soil (Ts), Poultry manure (Pm), Rice husk (Rh) and Oil palm refuse bunch (OPRB) were used. They were evaluated as sole treatments and in combination with river sand (Rs) in different ratios (1:1, 1:2, 2:5 and 5:2) respectively. Altogether, twenty one (21) potting media types were evaluated. The experiment was laid out in a completely randomized design (CRD) in three replications. Data were collected on monthly basis for plant growth parameters, while shoot and root dry weight were measured at the end of the experiment. On the average the seedlings of D. guineense responded best on the Rs + Ts 1:2 growth medium in number of leaves (16.67), stem girth (0.31 cm), number of nodes (11.67), shoot dry weight (1.24 g) and root dry weight (0.50 g). Rs + Ts 1:2 was followed by Rs + Pm 1:1 and Ts sole respectively with respect to the growth parameters evaluated and were not significantly (p 0.05) from one another, but were significantly (p < 0.05) different from other media and their combinations with river sand.

 Albizia niopoides (Bentham) Burkart, known as farinha seca, is an arboreal, deciduous and pioneer plant that can be found in the semi-deciduous forest in the Paraná basin. The study on the germination and growth of the plant is fundamental for better knowledge about the establishment and regeneration of the species. Aiming to verify the germination of A. niopoides and subsequent growth, green seeds and brown seeds were germinated in a germination chamber and growth parameters were evaluated at 60, 90, and 180 days after transplanting (DAT) in a greenhouse. There was no significant difference in germination percentage between green and brown seeds. However, lower levels of mean germination times and higher levels of germination speed index were observed for brown seeds. At 180 DAT, plants showed higher shoot dry mass, root dry mass, total dry mass, number leaves and height, with no significant difference between 60 and 90 DAT for total dry mass, root dry mass and root length. The values of stem height/diameter and Dickson quality index, associated to the other growth parameters, indicate quality of the seedlings for field planting at 180 DAT.

Grape (Vitis vinifera) waste management is a major problem in juice production, but it could be transformed into a major opportunity if the waste was recycled and used as a nursery growing medium. The aim of this study was to evaluate the suitability of four composts based on squeezed grape fruit waste (SGFW), mixed with coir or vermiculite in a one-to-one ratio by volume to form 13 growing media, for seed germination and seedling growth of ‘Mrs. Burns’ lemon basil (Ocimum basilicum var. citriodora). The final germination percentage (FGP), corrected germination rate index (CGRI), survival percentage, and seedling growth of ‘Mrs. Burns’ lemon basil were the variables measured. Pure SGFW reduced seed germination and seedling growth. The medium combining pure SGFW with vermiculite in a one-to-one ratio by volume was optimal for seed germination and seedling growth; in this medium the highest FGP, CGRI, survival rate, and growth parameters were recorded. The negative effects of pure SGFW composts were eliminated by mixing all composts with coir or vermiculite. These waste recycling media are low-cost products that can be beneficially used in nurseries on a commercial scale.
