Result Analysis

The experiments were conducted in the Forestry laboratory of Kebbi State University of Science and Technology, Aliero, Kebbi State. The studies were conducted from February 2020− March 2020 to assess the most effective method of breaking seed dormancy in Dialium guineense seeds. The seeds were subjected to four (4) pre-treatment methods (sulphuric acid, hot water, cold water and mechanical scarification) with untreated seeds as control, the experiment was laid out in completely randomized design (CRD) and replicated three (3) times. Final germination percentage (FGP), germination mean time (GMT), germination index (GRI), Coefficient Velocity of Germination (CVG) and Germination rate index (GRI) were calculated and the data was subjected to the analysis of the variance (ANOVA). Seed treated with cold water for 48 hours (Trt 1) started germination at two (2) days after sowing (DAS) and ended germination at 5 DAS, control and three of the treatments (Trt 2, Trt 5& Trt 7) started germination at 3 DAS while Trt 4 and Trt 8 started at 4 and 5 DAS respectively. FGP 100% was obtained from Control and Trt 5 and they finished Germination at 9 and 21 DAS respectively. Highest GI, GRI and CVG and lowest MGT were recorded from Trt 1. The result analysis of findings at 5% level of statistics showed that there is nosignificant difference between the treatments. Similarly, no germination on seeds in Trt 3 and Trt 6. Seeds of Dialium guineense are not limited by dormancy therefore can be sown without any pre-treatment, but for large scale production of Dialium seedlings it can be treated in cold water at room temperature for 48 hours due to availability and low cost with less risks.

Objective: Baobab (Adansonia digitata) is a native tree that is found in African savannas, it is a member of family ‘Malvaceae’. The tree is found in Nigeria, South Africa, Botswana, Namibia, Mozambique and in different regions of western Madagascar. Seed dormancy is the most limiting factor for some plants propagation. Dormancy allows seeds to separate from their mother plant and survive dispersal, over distance, and time before growth recommences. This study was aimed to determine the effect of three pre-treatments on breaking the seed dormancy of Adansonia digitata L., a multi-purpose and indigenously endangered tree. Methods: The study was carried out in the greenhouse of the Department of Biological Sciences, Federal University Dutsin-Ma, Nigeria. The three pre-treatments are: Soaking in hot water (100°C) for 5, 10, 15, and 20 min; and soaking in sulfuric acid (H2SO4) and hydrochloric acid (HCL) concentrations (100%, 75%, 50%, and 25%) for 5, 10, 15, and 20 min. Untreated seeds served as control. These were laid out in a complete randomized design with three replications. Data were collected on germination percentage, germination rate, day of emergence, and the average seedlings height. Results: The result showed that earliest mean days of emergence (7 days) were observed in seeds subjected to hot water treatment at 15 min. It also showed the highest rate of germination and percentage 6 (100%). On the other hand, the effect of acids (H2SO4 and HCL) pre-treatments on the seeds gave a fair result (16.66–33.33%), untreated seeds did not germinate. Conclusion: All the pre-treatments used in the study were found to be effective. However, soaking of seeds in hot water (100°C) pre-treatment for 15 min is recommended for breaking the seed dormancy of A. digitata.

This study was conducted to evaluate the effect of different methods of seed pre-treatment on germination of two indigenous tree species, Sweet dattock and Indian jujube (Detarium microcarpum and Ziziphus mauritiana). The experiment is carried out at the Tree Seedlings Nursery of Faculty of Agriculture, Kebbi State University of Science and Technology, Aleiro. Treatments consisted of Boiled water (100ºC) for 10 minutes, 20 minutes and 30 minutes; three levels of diluted sulphuric acid (H2S04) soaking time for 10minutes, 20 minutes and 30 minutes; Seed scarification and control. The treatments were arranged in Completely Randomized Design (CRD) with three replications per treatment. Results revealed that the seed of Sweet dattock (Detarium microcarpum) soaked in hot water at 1000 C for 30 minutes exhibited the best germination percentage (100.00±0.00) within four (96 hours) days. This is followed by hot water treatment for 10 minutes and sulphuric acid treatment for 20 minutes which gave the same germination percentage of 93.33±11.54 within 4 (96 hours) days. The seeds under control treatment gave the least germination percentage of 86.67±11.54 and took a longer period to germinate (eleven days.) Indian jujube (Ziziphus maurtiana) seeds on the other hand, gave the highest germination percentage (93.33±5.77) with scarification, followed by soaking in hot water for 30minutes (46.57±11.54), while the lowest germination percentage was recorded for seeds in the untreated control (3.33±5.77). Based on the result, pre-treatment of Sweet dattock (Detarium microcarpum) seed with hot water at 1000 C for 30 minutes and scarification of Indian jujube (Ziziphus maurtiana) seed is recommended for effective germination.

Screen house experiments were carried out to examine the effects of aqueous leaf extracts of Tithonia diversifolia (Ti) and Vernonia amygdalina (Ve), as well as NPK fertilizer (15-15-15) on the germination, growth and development of maize. Fresh leaves were collected, washed with tap water, chopped and pounded, soaked in distilled water and filtered. The two filtrates were used to prepare extracts at 50 and 100% w/v. Four maize seeds were placed in Petri dishes laid out in a completely randomized design with five replicates. In every Petri dish 10 ml of extract per treatment was added. A control experiment with distilled water was also set up. Also, in a completely randomized design with four replicates, 4-week-old potted maize plants were treated with 500 ml of each extract as well as with 1.52 g of NPK fertilizer. The results showed that the germination percentage of the seeds followed the order Ti50 - Control - Ve50. The seeds treated with aqueous extracts of T. diversifolia and V. amygdalina at 100% w/v produced lower but equal germination percentage. The seedling radicle growth was significantly inhibited by the aqueous extracts of Ti100, Ve50 and Ve100 (p?0.05). The inhibition was dose-dependent and more pronounced in seeds treated with extracts of V. amygdalina. The aqueous extract of T. diversifolia (50% w/v) and control influenced radicle growth substantially. All the extracts inhibited the plumule development compared to the control. On the other hand, growth, development and yield were not significantly affected by the plant extracts.

The evaluation of seed priming methods on the seed and seedling performance of soursop was conducted January 9 to April 3, 2019 in San Nicolas, Ilocos Norte, Philippines.  The study was conducted to investigate the effect of seed priming methods  capable of breaking dormancy; improve germination rate; determine the seed vigor of soursop; and identify the best seed priming method that provide better seedling performance. The experimental  treatments (unprimed and three priming methods, hydropriming, halopriming and hormonal priming) were laid out in Completely Randomized Design with three replications. A     total of 20 polyethylene bags were used per treatment per replication with one seed sown in every bag. Alternative way to improve seed and seedling performance is the use of these seed priming methods. The seed and seedling performance of soursop were significantly affected by priming methods. Primed seeds had higher percentage germination rate (PGR) than unprimed seeds. But numerically, the highest PGR was hydropriming. Hormonal priming produced significantly taller seedlings at 10 and 40 days after emergence (DAE) than unprimed seeds and more leaves per seedling at 30 to 50 DAE. Hormonal, hydropriming and halopriming produced significantly higher fresh weight of seedlings than unprimed seeds.

ABSTRACT: The goal of this work was to characterize morphometrically diaspores from three species of mistletoes (Passovia pyrifolia, Struthanthus marginatus e Phoradendron mucronatum), as well as to study its germination behavior according to temperature and luminosity. In germination tests, the completely randomized design was used, in factor scheme 4 x 2, with 4 replications of 15 diaspores. The factors for the first test were different temperatures and two diaspore conditions (intact and without epicarp). In the second test, factors were different light qualities and two diaspore conditions. The analyzed variables were: germination percentage, germination rate index (GRI) and mean germination time (MGT). Mistletoe’s diaspores present an elliptic shape with viscin layer, an essential characteristic for the dispersion of the species. In addition to this, they present a distinction as for the moisture content when compared to the Loranthaceae and Viscaceae, where the latter presents the highest content. Germination is greater at the alternated temperature of 20-30 oC for P. pyrifolia and P. mucronatum diaspores and 20 oC for S. marginatus. Luminosity interfered in the germination of P. mucronatum and S. marginatus but did not influence P. pyrifolia. The diaspore condition influenced the germination of the three studied species, observing a significant increase in their germination when the epicarp was removed. Temperature and luminosity interfere directly in the GRI and MGT of the three mistletoes species.

This research aimed to investigate the effect of various scarification treatments on the germination of tree saga seeds (Adenanthera pavonina L.). This study used a completely randomized design (CRD) with 6 treatments and 3 replications. The treatments in this study were P0 (control), P1 (soaked using distilled water for 24 hours), P2 (soaked using hot water 60 °C for 15 minutes), P3 (sanded skin), P4 (soaked using 1% H2SO4 for 30 minutes), and P5 (soaked using goat urine for 30 minutes).  The data obtained were analyzed by Analysis of Variance and continued with the Least Significant Difference Test (LSD) level of 5%. The results showed that the treatment had a very significant effect (P <0.01) on germination rate. The best treatment that can increase the germination of a tree saga seeds (Adenanthera pavonina L.) was by eroding the seed skin using sandpaper. This treatment can produce an average germination of 78.89%, while the treatment that produce the highest abnormal seeds was found in the treatment by soaking using 1% H2SO4 for 30 minutes.  The treatment that produce normal seeds, dead seeds, and the highest fungus-stricken seeds were found in the treatment by eroding the seed skin using sandpaper. The treatment that produced the highest hard seed was control.   Keywords: Germination, Saga, Scarification.
