Bean sprout is used as vegetables. The present study investigated the effect of temperature and light on seed germination and sprout yield, and proximate (crude protein, crude fat, crude fibre, nitrogen free extract and ash) composition of sprout in Lignosus (Dipogon lignosus (L.) Verdc.) and Mung (Vigna radiata Wilczek) beans. Three temperatures (ambient, 25 o and 30 o C) and two light regimes; continuous dark, (CD) and continuous dark alternated by ½ hour light daily, (DAL) were used for seed germination and bean sprout yield. Data were collected 24, 48, 72, 96 and 120 hours after setting the presoaked seeds in the petri dishes. Of the temperature regimes, generally better seed germination and sprout fresh weight (yield) were observed at 25 o C in Mung bean and 30 o C in Lignosus bean. Germination and sprout yield were similar under CD and DAL. Both under CD and DAL, sprout yield was higher after 120 hours compared to 96 hrs after germination in both the beans. Proximate composition of dry seeds and their sprouts was also determined. Irrespective of species, crude protein content was significantly higher in sprout (average of 29.33%) than dry seed (average of 24.33%).Vitamin C was significantly higher in Lignosus bean sprout (20.93 mg 100g -1 ) compared to Mung bean sprout (9.52 mg 100g). This is the first world report on Lignosus bean sprout. It may be concluded that better sprout yield and good protein content were obtained at 25

Summary: Résumé: Zusammenfassung California‐grown seeds of Paspalum distichum L., incubated at the optimum temperatures between 28°C and 35°C, gave 14% germination in darkness and 40% germination at 16‐h day length. The maximum and minimum limits for germination with light were >45°C and 10–22°C, respectively. The process of after‐ripening was accelerated by dry storage of the seeds at 50°C. Pre‐chilling at 6°C and a 2‐h heat treatment at 40°C had no effect on germination. Gibberellin A3 increased germination only up to 10%. The treatments that caused greater than 40% germination of seeds in the dark were immersion of the dry seeds in concentrated sulphuric acid (H2SO4) for 30–60 min, giving 60–95% germination; or in 700 mM sodium hypochlorite (NaOCl) for 1–8 h. giving 53–80% germination. The clearest results were obtained by treating the dry seeds with oxidants. H2SO4 being the most effective, followed by NaOCl and hydrogen peroxide (H2O2); the latter being effective only in the presence of light. The light‐induced stimulatory effect was decreased with increasing exposure of dry seeds to both H2SO4 and NaOCl. However, the light effect was still apparent in imbibed dormant seeds with 2‐h NaOCl immersion but not in dry seeds with the same treatment. The results of this study suggested that the seed dormancy in P. distichum was mainly imposed by seed coverings, including hull and seed coat membranes. Facteurs influençant la dormance et la germination des graines de Paspalum distichum L. Les semences d'origine californienne de Paspalum distichum L. incubées à des températures optimales entre 28 et 35°C, ont donné 14% de germination dans l'obscurité et 40% avec une longueur de jour de 16 heures. Les limites maximales et minimales pour la germination avec lumière étaient respectivement >45°C et entre 10 et 22°C. Le processus de maturation a été accéléré par un stockage des graines à 50°C. Un passage au froid à 6°C puis un traitement à chaud de 2 heures n'ont pas eu d'effet sur la germination. La gibberelline A3 a augmenté la germination de seulement 10%. Les traitements qui ont entraîné plus de 40% de germination dans l'obscurité sont l'immersion des graines sèches dans l'acide sulfurique concentre (H2SO4) pendant 30 à 60 minutes avec 60 à 95% de germination ou l'immersion dans l'hypochlorite de sodium 700 mM (NaOCl) pendant 1 à 8 heures avec 53 à 80% de germination. Les résultats les plus clairs ont été obtenus en traitant les grains secs avec des oxydants. H2SO4étant le plus efficace, suivi par NaOCl et le peroxyde d'hydrogène (H2O2); ce dernier étant efficace seulement en présence de lumière. L'effet inducteur de la lumière a moins d'importance avec une exposition accrue des graines sèches à H2SO4 et NaOCl. Cependant, l'effet lumière était encore apparent pour des graines en dormance immergées pendant 2 heures dans NaOCl mais pas pour des graines sèches ayant subi le même traitement. Les résultats de cette étude donnent à penser que la dormanee des graines chez P. distichum est due principalement à la couverture d...

A series of controlled experiments were conducted at 13 constant temperatures (10-42 C) in the dark to examine effects of temperature on bud-sprouting of Cyperus esculentus tubers and early growth of their sprouts. Percent sprouting increased with increasing temperature within the range of 12 to 38 C, while no sprouting occurred at 10 C and few tubers sprouted at 42C. The rate of sprouting also increased with temperature up to 35 C. A base temperature of 11.4 C was determined for bud-sprouting of tubers in this species. Higher temperatures led to larger sprouts and greater survival rate. In particular, increased temperature favored root growth, and hence resulted in high root : shoot ratio of the sprouts. Larger tubers produced larger sprouts as a consequence of mobilizing a greater amount of their reserves, but they tended to utilize a smaller proportion of their reserves. The efficiency of reserve utilization significantly differed among the incubation temperatures, and its relation with temperature followed a quadratic pattern. This pattern is different from that documented for the bud -sprouting of rhizomes and stolons of other perennials. Our results demonstrate that temperature is crucial to the successful establishment of C. escu/entus.
