Variation in the Response of Seed and Embryonic Axes to Incubation Temperature Gradients during Seed Treatments in Pearl Millet and Sorghum JARTS
Kader, Mohamad A.; Director, Consultica Worldwide, PO Box 3089 Tamarama NSW 2026 Australia email: m.kader@mbox.com.au.
Incubation temperature during the presowing soaking of seeds plays a significant role in determining the rate and characteristics of post-treatment germination. Three experiments were conducted on sorghum (Sorghum bicolor L Moench) and pearl millet (Pennisetum glaucum L. R. Br.) genotypes to determine the influence of constant, alternating, ascending and descending temperature regimes on germination characteristics of seeds after treatment. Incubation temperatures ranging from 10 to 35°C were applied as well as alternating the magnitude and range of day/night temperatures. A third experiment tested a 3-day temperature gradient and its impact on germination and seedling characteristics. All three incubation temperature regimes were combined with...

Variation on embryo development of Ilex paraguariensis Seeds PFB - Pesquisa Florestal Brasileira
Fowler, João Antonio Pereira; Sturion, José Alfredo; Zuffellato-Ribas, Katia Christina.
Ilex paraguariensis St.Hil., popularly named erva-mate in Brazil, is an indigenous species of the Araucaria Forest with a large geographic distribution and a high social and economic importance. The seeds of this species exhibits physiologic and seed coat  impermeability dormancies and needs stratification on sand in order to break them. This work aimed to evaluate the influence of genotype -environment interaction on embryo development of erva-mate seeds formed under different environmental conditions. The fruits were collected in Cascavel, Toledo and Campo Mourão, State of Paraná, and in Soledade, State of Rio Grande do Sul, in February 2003. The experiment was carried out on Forest Seed Laboratory of Embrapa Florestas, in a completely randomized design...

Objetivou-se com o presente trabalho estudar a perda de viabilidade das sementes de duas variedades de Vigna unguiculata, acondicionadas em embalagens de papel e recipiente metálico, armazenados em ambiente não controlado. Após a colheita das sementes, em campos preparados para esta finalidade, as mesmas foram beneficiadas manualmente, tratadas, acondicionadas e armazenadas, para que a cada dois meses fossem avaliadas quanto a sua qualidade fisiológica mediante teste de germinação, indicando a melhor capacidade armazenadora para a condição do estudo. A análise dos dados foi realizada no delineamento inteiramente casualizado, disposto em esquema fatorial 2 x 2 x 2 x 6 com 4 repetições, sendo os fatores quantitativos revelados pela regressão na análise de...

ZORATO, M. de F.; HENNING, A.A..
Foi estudada a viabilidade de utilizacao e a influencia de dois agentes veiculadores de fungicidas: agua e solucao aquosa que continha nonilfenol oxietilato, alcool isopropilico e alcool polivinilico, em sua composicao, aplicados em diferentes epocas de armazenamento, na qualidade de sementes de soja. Foram conduzidos dois experimentos, utilizando sementes da cultivar Paiaguas, produzidas e armazenadas em Pedra Preta, MT e sementes da cultivar BR-16 produzidas e armazenadas em Ponta Grossa, PR. Os fungicidas e suas concentracoes [g de ingrediente ativo/100kg de sementes] foram os seguintes: thiabendazole (17) + thiram (70); carbendazin (30) + thiram (70); carboxin (50) + thiram (50). Esses foram veiculados com os agentes ja descritos nas doses de 100ml,...

Saldanha, Cleber Witt; Missio, Evandro Luiz; Steffen, Gerusa Pauli Kist; Maldaner, Joseila; Morais, Rosana Matos de.
This study aimed to assess the physiological quality of Parapiptadenia rigida (Benth.) Brenan seed weight classes subjected to accelerated aging under laboratory and greenhouse conditions. A lot of P. rigida seeds was split in three seed weight classes (thousand seed weight): TSW1 (original lot; control, 19.23 g), TSW2 (25.45 g) and TSW3 (13.58 g), which were subjected to three accelerated aging times (0, 24 and 48 h). First count, weak and strong normal seedlings, percentage of accumulated germination, percentage of death seed, electrical conductivity, fresh and dry weight and shoot length were assessed in laboratory. Seedling emergence, emergence velocity and emergence velocity index were assessed in greenhouse. P. rigida seeds showing higher weight...

การยืดอายุการเก็บรักษาเมล็ดพันธุ์หลักในสภาพควบคุมอากาศและความชื้น Thai Agricultural
Orak Thongdej; Anchalee Prasertsak.
Storage is a major problem for foundation seed production. Occasionally, deterioration occurred before planting time and low germination was shown. The experiment on extending storability of foundation seed in hermatic condition was conducted in Phatthalung Rice Research Center between May 2011 – April 2014. The two varieties; Chiang Phatthalung and Phitsanulok 2 were used in this experiment. Seed moisture content of approximate 10 tons in each variety was reduced to 10.44 and 11.24% in Chiang Phatthalung and Phitsanulok 2, respectively. Seeds were then put in plastic bag and stored in hermatic condition (cocoon) compared to normal storage (control). It was found that Chiang Phatthalung and Phitsanulok 2 stored in cocoon showed 90 and 96% germination...

Seed drying to suitable moisture content during harvesting immediately and storage is a key factor to maintain a long-shelf life. The purpose of this research was to use the zeolite drying beads to dry rice seeds var. Phitsanulok 2 (PSL2) and Ayutthaya 1 (AYT1) to target moisture content at 6 % and 12 %. Three experiments were carried out at Prachinburi Rice Research Center during April 2012- January 2013. Rice seeds with the different initial moisture content were blended with three beads to seed ratios at 30oC, 40oC and ambient temperature. The results revealed that rice seed moisture content could be reduced to the target moisture content which depended on variety, initial moisture content, the bead-to-seed ratio, drying temperature and drying...

Assiri Klangsawad; Petcharat Thummabenjapone.
Using plant growth promoting microbes is an alternative approach for reducing cost and enhancing good health of crop plants. This research aims to establish the application protocol for enhance growth of tomato at seedling and transplanting stages by antagonistic Streptomyces-PR87 which will be applied further to farmer. The experiments were carried out using two varieties of tomato, e.g. var.Sida and var.Tomato32. In seedling stage, the experiments were carried out in combinations with Streptomyces-PR87 concentration at OD600=0.2, 1 and 5 and drenching interval at 3, 5 or 7 days, and seed soaking for 24 hours before sowing or directly drenching after seed sowing methods. The results showed that the most appropriated method for enhance growth and...

玉米種子發芽之耐銨性及耐性組合力分析 Taiwan Agricultural Research Institute
謝光照; 曹文隆; 楊金興; 盧煌勝; Guang-Jauh Shieh; Wen-Long Tsaur; King-Hsing Yang; Hung-Shung Lu.
[[abstract]]以6個玉米自交系及其相互雜交所獲得的30個Fl單交種為材料,在銨離子〔NH4+〕5種(0, 5, 25, 50, 100mM)濃度下,於恆溫(36±1℃)生長箱中進行發芽試驗。變方分析結果顯示銨離子濃度間、基因型間與銨離子濃度x基因型間之交感作用對所有發芽性狀均有極顯著之影響。其中發芽率、3日發芽勢和發芽係數呈現隨著銨離子濃度之增加而下降之趨勢,當銨離子濃度達50 mM以上時,即明顯的阻礙種子發芽。不同的基因型間其耐性程度也有所差異。由Griffing 之組合力分析,顯示平均發芽時間、發芽率、3日發芽勢和發芽係數均受一般組合力 (GCA)、特殊組合力 (SCA) 及正反交效應 (RE) 等遺傳基因所共同影響,其影響力之大小呈現GCA>RE>SCA之趨勢。在高銨濃度下 (50 mM以上)其GCA/SCA均方比值呈現小於低銨濃度(5-25mM)。所使用的自交系中以TA85-17、H95及A661具有較佳之耐銨性,而F1單交種中以ICAL210xA661、TA85-17Xa661及A661xTA85-17表現最佳之耐銨性。

臺南白玉米族群發芽之溫度反應 Taiwan Agricultural Research Institute
楊舒惠; 謝光照; 吳詩都; Shu-Hui Yang; Guang-Jauh Shieh; Shu-Tu Wu.
[[abstract]]為探討台南白玉米族群發芽之溫度反應及種子發芽最低、最適與最高三種基本溫度,本試驗將台灣不同地區(屏東、高雄、台南、雲林、台中、台北、花蓮、台東)所蒐集之台南白族群,於台中地區繁殖之後代為材料,利用生長箱於不同溫度下進行發芽試驗。試驗結果,八個族群各發芽性狀之溫度反應,一般皆呈發芽溫度愈高而發芽始期、有效發芽期間及平均發芽時間愈短之趨勢;而發芽率及發芽係數隨溫度升高而增加,至20℃~30℃時八個族群皆可達到最大,然而當溫度提升至35、40℃時則下降。綜合發芽率最高且平均發芽時間最快之溫度範圍,可知屏東、台南、雲林、台中、花蓮及台東族群最適發芽溫度為25~30℃,而高雄及台北族群最適發芽溫度則為30℃。八個地區族群種子最高發芽溫度為40~45℃。利用種子發芽所需最低溫及溫度時問估算式求得八個台南白玉米族群發芽最低溫之變異幅度為2.9℃~3.5℃,而發芽溫度時間之變異幅度為55.1~59.0℃d。
