“…Seed treatment is to ensure to both enhance and uniform germination (Azad et al 2006a). The effect of pre-sowing treatments on seed germination of some tropical forest tree species are reported (Ahamed et al 1983;Matin and Rashid 1992;Bharwas and Chakraborty 1994;Ali et al 1997;Koirala et al 2000;Khan et al 2001;Hossain 2005a and2005b;Matin et al 2006;Azad et al 2006aAzad et al , 2006bAzad et al , 2010aAzad et al and 2010b. However, there are few documents available on the effect of pre-sowing treatment of A. auriculiformis.…”

Seed morphology, germination and seedlings growth of Acacia auriculiformis were studied. The experiment was conducted in the nursery of Forestry and Wood Technology Discipline, Khulna University, Bangladesh. Matured seeds of the species were collected from healthy trees of road side plantation from different areas of Khulna District, Bangladesh and treated with five pre-sowing treatments (control, immersion in cold water, immersion in hot water, scarification with sand paper and immersion in concentrated H 2 SO 4 ). The average length, breadth and thickness were found to be (0.58±0.017) cm, (0.44±0.007) cm and (0.20±0.089) cm, respectively. Germination was conducted in polybags with a mixture of top soil, coconut husk, coarse sand, and fine sand in a ratio of 3:4:1:1. Results reveal that pre-sowing treatments influences the germination rates of seeds that significantly increase the percentage germination compared with those in control (43%) and cold water treatment (52%). The highest germination success rate was found 83% in hot water treatment followed by 78% in scarification with sand paper, and 75% with immersion in H 2 SO 4 . Germination started from 7 to 12 days and completed between 28 and 35 days period in all treatments. ANOVA showed the significant difference (p<0.05) among the treatments in seed germination, but no significant difference among treatment with regard to starting day, closing day and total germination period. In case of height and diameter growth, seedlings originated from the seeds with hot water treatment shows significantly higher in wet season (from May to July).Hot water treatment can be recommended on seed germination of the species in rural Bangladesh.

“…By this time, it is successfully practiced in some middle and northern part of the country, but there are scarcity of planting materials due to poor seed germination percentages. Intensive plantation in agroforestry, social forestry, and home garden is limited because of destitute seed germination and delayed nursery establishment (Azad et al, 2010a;2010b). Germination success can be improved through adopting appropriate presowing techniques (Maguire, 1962;Koirala et al, 2000;Alamgir and Hossain, 2005a;2005b;Azad et al, 2006a;2006b).…”

A new experiment on seed germination technique for Phoenix dactylifera, an exotic species was conducted in the nursery of Forestry and Wood Technology Discipline, Khulna University, Bangladesh. The seeds imported from Saudi Arabia were collected from Nirala Central Mosque, Khulna, Bangladesh, in September 2008 and treated with four presowing treatments (control, immersion in normal water at room temperature (20-22°C) for 12 h, immersion in sun-heated water (25-35°C) for 12 h, and immersion in hot water (50°C) for 10 h) before seed germination with different germination media (well dried loamy soil, coarse sand, mixture of coarse and fine sand at a ratio of 3:1, mixture of coarse and fine sand at a ratio of 3:2, and mixture of coarse and fine sand at a ratio of 1:1). The experiment showed that presowing treatments significantly increased the germination rates of seeds compared to those in control (68%) and hot water treatment (69%). The highest germination success (84%) was found in the immersion in normal water and sunheated water for 12 h. Experiment also showed that seed germination with course sand and mixture of coarse and fine sand with a ratio of 3:1 performed better than the loamy soil. Germination started from 21 to 26 days and completed between 38-40 days of the germination period in all treatments. ANOVA showed a significant difference among the treatments in seed germination, but there was no significant difference among the media in seed germination. Normal water and sun-heated water for 12 h for pretreatment and coarse sand or mixture of coarse and fine sand at a ratio of 3:1 may be recommended for seed germination of the species in rural Bangladesh.

“…Para Albizia richardiana, espécie nativa da Ásia, o tratamento utilizando água quente com temperatura a 80 °C por 10 minutos não danificou as sementes e promoveu a germinação de 96%, em relação aos 49% do controle (Azad et al, 2010). Para a espécie A. procera, a água quente a 80 °C por 10 minutos elevou em aproximadamente 20% a germinação em relação à testemunha (Sajeevukumar et al, 1995;Azad et al, 2012).…”

“…Albizia hassleri superou a dormência com a imersão das sementes em ácido sulfúrico por apenas 1 minuto (Fowler et al, 2006) e A. lebbeck, com a imersão por 1 a 5 minutos (Sequeira et al, 2002). A. falcataria e A. procera precisaram de 10 minutos de imersão (Sajeevukumar et al, 1995) e A. richardiana apresentou bons resultados com imersão em ácido sulfúrico por 20 minutos (Azad et al, 2010). Para muitas espécies de outros gêneros e famílias já foi constatado o benefício na germinação com a imersão em ácido sulfúrico por períodos maiores que 20 minutos, denotando maior resistência dos tecidos germinativos a esse tratamento.…”

RESUMOO trabalho teve como objetivo avaliar a eficiência de métodos de quebra de dormência em sementes de Albizia pedicellaris em laboratório. Foram aplicados 10 tratamentos pré-germinativos: escarificação química com imersão em ácido sulfúrico por 5, 10, 15 e 30 minutos, escarificação física, seguida ou não de embebição em água por 6, 12 e 24 horas, choque térmico e testemunha. Foi utilizado o delineamento inteiramente casualizado com 4 repetições, com 25 sementes por unidade experimental. Os seguintes parâmetros foram avaliados: percentual de germinação, índice de velocidade de germinação, número de plântulas normais, número de plântulas anormais, mortalidade. Com base nos resultados indicam-se como tratamentos para quebra de dormência da A. pedicellaris a escarificação mecânica seguida ou não de embebição por 6 ou 12 horas ou a imersão em ácido sulfúrico por 30 minutos.Palavras-chave: germinação, sementes florestais nativas, sementes duras. Dormancy breaking of Albizia pedicellaris (DC.) L. Rico seeds ABSTRACTThe study aimed to evaluate the efficiency of seeds dormancy breakage methods for Albizia pedicellaris in laboratory. Seeds were treated with ten pre-sowing treatments: chemical scarification using sulfuric acid for 5, 10, 15 and 30 minutes, physical scarification followed or not by immersion in water for 6, 12 and 24 hours, thermal shock and control. Completely randomized design was used with four replications of 25 seed per experimental unit. The followings variables were evaluated: germination percentage, speed germination index, normal seedlings number, abnormal seedling number, and mortality. The results indicate that the most efficient method to overcome dormancy was mechanical scarification followed or not by immersion for 6 or 12 hours or immersion in sulfuric acid for 30 minutes.
