Background: Rice (Oryza sativa L.) is a major cereal crops planted in Thailand for both local consumption and export. The objective of this study was to investigate the allelopathic effect of Caesalpinia sappan L. and Crateva magna (Lour.) DC. extracts in promoting a rice cultivar, Khao Dowk Mali 105 (KDML105) seed germination and seedling growth, at 7 and 14 days after sowing (DAS). Methods: The C. sappan and C. magna plants were cleaned with tap water and air dried in room temperature then cut into small pieces and ground into fine powder. Plant crude extracts was prepared using ethanol as solvent. Result: The results showed that rice seed treatment with C. sappan and C. magna extracts was significant (all p less than 0.05), increasing root length, shoot fresh and dry weight and root fresh and dry weight of rice seedlings at 14 DAS. Seed treatment with these two plant extracts led to a significantly greater vigor index of the KDML105 rice seedling cultivar, when compared with the control. Interestingly, the seed treatment with C. magna extract at a 100 ppm concentration was found to produce the highest enhancement in the overall rice seedling growth parameters, including the vigor index of seedlings. The results showed that a low concentration of C. magna extracts can be potentially used in promoting seedling growth of rice since they improved the overall growth parameters.

An experiment was conducted at the Seed Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh during the period from January to April 2012 to study the effect of hydropriming on field establishment of seedlings obtained from primed seeds of Boro rice cv. BRRI dhan29. Seeds were soaked in water for 0, 24, 30, 36, 42, 48, 54 and 60 hours. The incubation period was 30 hours at 35°C temperature. Seed quality viz. percent germination, mean germination time, vigor index, shoot length, root length, shoot dry weight and root dry weight of rice seedlings were measured. Plant population m-2 also recorded to understand the field establishment of primed seeds. It was observed that priming treatments had significant effect on germination and other growth parameters of rice seedlings. The highest germination, vigor index, population m-2, length of shoot and root and their weight were found at 15 and 30 DAS. The lowest mean germination time was observed from hydropriming of seeds with 30 hours soaking. On the contrary, no priming treatment showed the lowest germination, vigor index, population m-2, and the highest mean germination time. The study concludes that BRRI dhan29 rice seed could be primed for 30 hours as hydropriming improves germination and field establishment of rice seedlings of Boro rice cv.

The experiment was conducted in the Agronomy Laboratory of Agrotechnology Discipline, Khulna University, Khulna from 29th August to 17th September, 2009. The experiment was laid out in a Completely Randomized Design (CRD) with two factors and three replications. The aim of the experiment was to study the efficacy of three osmopriming agents viz ., NaCl, KC1 and CaCb with control on seed germination and seedling growth of three T. aman rice varities viz., BRRI dhan40, BRRI dhan41 and BINA dhan7. Among the chemicals CaCb showed best as osmopriming agents and it enhanced all germination parameters. BRRI dhan41 showed the best performance. Better root length and shoot length were observed in control. Seeds of BRRI dhan41 when treated with NaCl showed the highest germination percentage (98.67%), germination energy (88%), germination speed (96.83%), but vigor index (10.63) was found highest in BRRI dhan40 when it was treated with KC1. BRRI dhan41 produced the largest root (8.56 cm) when seeds were treated with NaCl. BRRI dhan40 (10.51 cm) and BINA dhan7 (10.53 cm) produced the highest shoot length at controlled condition and CaCl2 treated seed, respectively.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12013   J.

An investigation was undertaken on two medicinally important evergreen tree species of Western Ghats namely, Elaeocarpus munronii and Canarium striuctum to improve seed germination and enhance seedling growth in nursery. The seeds collected from two randomly chosen trees in each species were used for the study. In general seed germination was very poor in both the species. The maximum germination of 4.66 per cent was observed in Elaeocarpus munronii and it was 13.33 per cent in Canarium striuctum. Though big and medium size seeds recorded higher germination per cent than small size seeds in both the species studied, the seed size effect on germination was found to be non-significant. The results of the study revealed that seed size did influence seedling growth in both the species. Seeds of bigger size produced seedlings with higher values of shoot length, root length and collar diameter but their effect on dry matter accumulation was not significant. The effect of seed treatments on seedling growth was not noticed in Elaeocarpus munronii while seed treatment with sulphuric acid in Canarium striuctum showed slight but significant increase in shoot length, however, other growth parameters remained unaffected. The effects of seed size as well as of seed treatment on germination and seedling growth was found to be similar in both the trees species studied.

An experiment was conducted during T. Aman 2010 and Boro 2010-11 seasons to determine the effect of industrial effluents on seed germination and seedling growth of rice. In both the seasons, all the effluents and city waste water (CWW) had no effect on rice seed germination except pharmaceutical effluent. Pharmaceutical effluent showed the lowest seed germination. City waste water gave the highest shoot length (8.40 and 5.38 cm) and root length (8.06 and 6.35 cm) in the T. Aman and Boro seasons, respectively. Pharmaceutical effluent gave the highest shoot-root ratio of 10.49 while tannery effluent gave lowest ratio of 0.91. In both T. Aman and Boro seasons, seedling weight with and without endosperm, seedlings dry weight, seedling strength were found higher with CWW. During T. Aman and Boro seasons, relative germination ratio showed higher with a beverage effluent but relative shoot and root elongation ratio were found higher with CWW managed treatment. Dhaka Univ. J.

Smoke Water

The ecologic significance of smoke-related seed germination is now well recognized. Consequently, smoke solutions and a pure butenolide, the active compound from smoke that stimulates germination of a number of plant species, show great potential for enhancing the growth of vegetable crops. Achieving maximum production and better and faster growth of the seedlings has always been a priority for vegetable growers. This study therefore highlights the effects of foliar application of smoke-water and a butenolide on seedling growth of okra [Abelmoschus esculentus (L.) Moench] and tomato (Lycopersicon esculentum Mill.). Treating okra seedlings with smoke-water (1:500 v/v) showed a significant (P < 0.05) increase in shoot/root length, shoot fresh/dry weight, number of leaves, total leaf area, and stem thickness compared with the control treatment. Treatment of okra seedlings with smoke-water significantly (P < 0.05) increased the absolute growth rate (AGR) per week. However, the seedling vigor index (SVI) did not improve as a result of no change in root fresh weight. On the other hand, foliar application of smoke-water and butenolide showed a pronounced effect on the seedling growth of tomato. Most of the growth parameters examined for both the treatments were significantly (P < 0.05) increased, resulting in a significantly (P < 0.05) higher SVI and AGR than the control. This study indicates that the foliar application of smoke-water or butenolide may be a useful and inexpensive technique for enhancing seedling growth of vegetable crops.

Beauveria bassiana (Balsamo) Vuill. is an entomopathogenic fungi can live  endophytic on different kinds  of plants. B. bassiana also play a role as growth promoters that  improves seed germination and growth of plant.  The effect of increased duration of seed treatment with Beauveria bassiana on seed germination and seedling parameters in chili were assessed in laboratory and field conditions. Chili seeds were soaked in the conidial suspension of B. bassiana in a concentration of 1 x 108 conidial / ml or in sterile distilled water for 3, 6, 9, and 12 h. Seed germination percentages and the vigor index were significantly affected by the application of B. bassiana. Overall, seed germination, the vigor index and plant growth of chili were significantly enhanced as seed treatment duration increased.  B. bassiana can also accelerate seed germination of chili and increase of seedling growth. Soaking the seeds with a B. bassiana suspension for 9 hours is the best time to increase of seed germination and seedling growth of chili

The experiment was carried out in the Seed Laboratory of Bangladesh Agricultural Development Corporation (BADC), Gazipur during June to July 2014 to investigate the effects of different priming methods on seed germination and the seedling growth of some rice (Oryza sativa L.)  varieties. Four rice varieties: 1) Nerica, 2) BRRI dhan51, 3) BRRI dhan41 and 4) BRRI dhan49; and six priming treatments: 1) On-farm Priming, 2) Hardening, 3) Hydro-priming, 4) Osmo-hardening, 5) Vitamin C Priming and 6) Control were used in the experiment. The experiment was laid out in a completely randomized design (CRD). The treatments were replicated three times. The germination percentage and seedling growth parameters differed significantly among the priming treatments. For germination, Nerica variety showed poor performance, whereas the other varieties were found superior. Among the priming treatments, Vitamin C priming and Osmo-hardening were found superior. In case of interaction, germination was increased with Vitamin C priming and Osmo-hardening in Nerica. For seedling growth parameters, particularly vigor index, shoot and root lengths, BRRI dhan41 and BRRI dhan51 were found superior. The priming treatment Vitamin C and Osmo-hardening performed better than others.  Seedling vigor index was increased with Vitamin C priming and Osmo-hardening in Nerica variety. Shoot length at 15th day was influenced by hydro-priming in Nerica. Root length at 10th day was significantly increased with hardening in BRRI dhan41. Vitamin C priming and Osmo-hardening could therefore, be used for improving germination and seedling growth of Nerica. The Agriculturists 2018; 16(1) 34-43

The effects of oil-contaminated soil on plant growth are the focus study area all over the world. In this paper, two kinds of local plant seeds germination and seedlings growth in oil-contaminated soil were studied by germination experiment. Five different oil concentration gradients (0g/kg, 0.2g/kg, 5g/kg, 20g/kg, 40g/kg) were set up in this experiment, and the seed germination rates and bud length of wheat and rice cultivated in thermostat were observed and recorded. The results showed that crude oil took negative effects on wheat seed germination and germinability. With the oil concentration increasing, the germination rate of wheat seed and germinability decreased respectively. Crude oil impacted the seeding growth obviously, even under low oil concentration (20g/kg). Seedling growth almost stopped under high oil concentration such as 40 g/kg. Crude oil promoted germination and germinability of rice seed. The germination rates and germinabilities of three Oil concentrations (0.2 g/kg, 5 g/kg, 20 g/kg, 40 g/kg) were all higher than that in pure soil, further, the higher the oil concentration was, the germination rates and germinabilities were higher. Oil also accelerated the rice seedling growth under three different concentrations.

In contrast to other toxic trace metals, Cr has received little attention. Since valence level of chromium determines its toxicity, chromium is categorized as unique heavy metal. Chromium hexavalent (Cr6+) has the biggest toxicity among other valence levels. Seed germination and seedling growth are sensitive to heavy metal stresses. This research aimed to find out the responses of seed germination and seedling growth of 12 sorghum varieties toward Cr6+. Seed germination and seedling growth experiment was done on 12 sorghum varieties (Badik, UPCA-1, Keris, Keris M3, hegari Genjah, Gambela, Selayer, Sangkur, Mandau, Batari, Kawali, dan Numbu), planted in petridishes with Cr6+ treatment in form of chromate (K2CrO4) and dichromate (K2Cr2O7) compounds with 0, 50 and 500 mg of Cr/l concentration for a week. The parameters measured were the number of seeds germinate each day; the length of radicle and plumule, and fresh and dry weight at the end of experiment. The results showed that higher concentration of Cr6+ both in form of dichromate and chromate, significantly decreased  the length of radicle and plumule, fresh and dry weight, and SVI (seedling vigor index) value. However, index germination (GI) value and percentage of germination of the 12 varieties sorgum significantly increased in the treatment of 50 mg Cr/l Cr6+ in form of dichromate and chromate. The treatment of dichromate compound showed bigger effect than chromate toward variables of seed germination and seedling growth of sorghum. It was noticed that 12 sorghum varieties possessed an integrated complex of adaptation to cope with the range of form of compound and concentration of Cr6+. Based on the responses of seed germination and seedling growth, Kawali, Hegari, Keris, Keris M3, Mandau, and Selayer varieties was more susceptible toward Cr6+ toxicity, and Sangkur, Selayer, Batari, and Numbu was more tolerant than other varieties.
