Responses of Lens esculenta Moench to controlled environmental factors
No full textMany experiments were undertaken to study the responses of the lentil cultivars 'Large blonde' and 'Anicia' to controlled environmental factors. They covered different aspects of the physiology and the ecology of the crop.The orientation experiments (2) involved germination and depth of sowing. The optimum temperature range for the germination of 'Large blonde' was 19-29 °C whilst that of 'Anicia' was 21-25 °C. The depth treatments (1, 4 and 8 cm) caused no particular effects on flowering and stem elongation. They brought about a general linear response of the cultivars with respect to average leaf production (Fig. L) The 4-cm treatment appeared to be the most favourable for dry matter production. A temperature of 23°C and a depth of 3 cm were used to pregerminate and sow the seeds respectively in carrying out further experiments.Studies on the photoperiodic requirements of the cultivars (3) led to differences between 'Large blonde' and 'Anicia'. The first cultivar behaved as a qualitative long- day plant: it did not flower at photoperiods shorter than 14 hours. 'Anicia' reacted quasily as a day-neutral plant. It flowered under all the photoperiods (8-16 hours) used, but came somewhat earlier into flower at 15 and 16 hours. The dry matter production of the cultivars seemed not to be influenced.The effects of the following temperature regimes: 9°C (night)-15°C (day), 13°C (night)-19°C (day), 17°C (night)-23°C (day), 21°C (night)-27°C (day), 25°C (night)-31°C (day) and 29°C (night)-35°C (day) on the plants of both cultivars were investigated (4). The treatment 21-27°C (average 24°C) led to the maximum leaf production, stem length and dry matter production. The regime 29-35°C was particularly detrimental to the growth of the cultivars: the plants were prematurely harvested before death occurred.An experiment was also conducted on daily amplitudes of temperature (5). It was carried out with three temperature regimes: 18 °C (night)- 30°C (day), 21 °C (night)- 27°C (day) and constant 24°C. The amplitude of 6°C (21°C-27°C regime) led to the highest average stem elongation, leaf and dry matter productions.The photosynthesis of 'Large blonde' and 'Anicia' was not influenced in a definite way by the (instantaneous) temperatures of 18°C, 24°C and 30°C (6). The photosynthetic capacity of the cultivars was similar. The surface they formed per unit dry weight was different, the ratio leaf area (dm 2)/dry weight (g) of 'Anicia' being higher than that of 'Large blonde'.The study of the drought tolerance of the cultivars under four frequencies of watering (3, 4, 8 and 12 times a month) brought out treatment-dependent differences in leaf area, stem elongation, dry matter production and evapotranspiratio (7). These features increased with a raise of the level of watering. The final water content of the plants was not clearly affected by the regimes.The tolerance to salinity and exchangeable sodium (in terms of ESP) was also brought under investigation (8). The cultivars were subjected to the influence of four salt concentrations corresponding with 1.2,4.5,8.4 and 13.1 mmhos/cm. In general, increase in the salt concentration resulted in an increased reduction of stem length and dry matter output. This depressing effect of salt was coupled with a continuous accumulation of Na and Mg in the plants. The tolerance limits of the cultivars were found to be between 8.4 and 13.1 mmhos/cm.The cultivars responded also clearly to the following ESP levels: 0.48, 4.53, 6.63 and 9.98. The higher the ESP level was, the larger became the growth reduction and the Na accumulation.Data on the growth and development patterns of 'Large blonde' and 'Anicia' were recorded in the course of an experiment which lasted 16 weeks (9). Both cultivars showed their greatest relative growth rate (RGR) between the second and the fourth weeks after sowing (0.81 g/g/week for 'Large blonde' and 0.85 for 'Anicia'). The final dry matter yields per plant of 'Large blonde' and 'Anicia' were comparable (4.7 and 4.5 g respectively). The seeds of the first cultivar represented 11 % of the final dry matter of the plant whilst those of the second accounted for 24 %. The highest shoot/root ratios (4.7 and 6.3 for 'Large blonde' and 'Anicia' respectively) were registered at the conclusion of the experiment

Club 44: 356. 1917): [icon] " Cassia calycibus acutis, floribus pentandris" in Linnaeus, Hort. Cliff.: 497, t. 36. 1738. Current name: Chamaecrista nictitans (L.) Moench (Fabaceae: Caesalpinioideae). Note: In order to distinguish between this name and Chamaecrista nictitans Moench (non (L.) Moench), Reveal (in Taxon 41: 135. 1992) proposed the conservation of the Moench name with the same type as the Linnaean name. However, this was not recommended by the Committee for Spermatophyta (in Taxon 43: 273. 1994) who voted that Ch. nictitans be treated as a new combination based on C. nictitans L., the proposal therefore being unnecessary.Published as part of Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part C), pp. 370-473 in Order out of Chaos.

Potential for the Exploitation of Nutritional Traits of Sweet Sorghum (Sorghum bicolor (L.) Moench) in Food Systems
No full textSweet sorghum (Sorghum bicolor (L.) Moench) is a drought-tolerant small-grain cereal which is cultivated largely by smallholder farmers in sub-Saharan Africa. It has potential as a dual-purpose crop. The grain is rich in antioxidants, and the stalks accumulate nutritious juice that can be processed into ethanol or syrup. The sweet sorghum syrup contains lower sucrose and total sugar but greater amounts of organic acids and minerals than sugarcane syrup. The biomass is used for livestock feeds. Currently, there is substantial diversity in the sweet sorghum germplasm collections from various African countries. In the future, there will be merit in enhancing sweet sorghum cultivars, probably through cytoplasmic male sterility systems. Mutation breeding, in conjunction with modern molecular tools, could also be useful in future breeding efforts. Promoting the use of sweet sorghum as an ingredient in the food and pharmaceutical industries can also offer new opportunities in the value chain

Moisture sorption characteristics and modeling of energy sorghum (Sorghum bicolor (L.) Moench)
No full textAbstractLong-term low cost storage of whole-stalk lignocellulosic energy sorghum biomass (specialized forage varieties of Sorghum bicolor (L.) Moench) is essential for the feedstock's successful role as a dedicated energy crop for ethanol production. As an alternative to expensive ensiling methods, aerobic storage of S. bicolor (L.) Moench biomass in traditional rectangular bale formats could alleviate feedstock supply costs if material deterioration in storage could be minimized. Moisture desorption and adsorption isotherms for S. bicolor (L.) Moench were created at 15 °C, 20 °C, 30 °C, and 40 °C with water activities from 0.1 to 0.9 using the dynamic dew-point method. Sorption isotherms were modeled using four temperature dependent and three temperature independent equations. The relationship between equilibrium moisture content and water activity was found to decrease with increasing temperatures. GAB (Guggenheim–Anderson–de Boer) monolayer moisture content and the moisture content at which microbial activity becomes limited were found to range from 5.6% db to 10.4% dry basis (db) and 12.0% db to 18.4% db, respectively. The net isosteric heat of sorption was calculated using the Clausius–Clapeyron equation and determined to be higher for desorption than adsorption with both trends decreasing exponentially at increasing levels of moisture content. The differential entropy of S. bicolor (L.) Moench was shown to exhibit a log normal relationship with moisture; peaking near the monolayer moisture content. The results of the study indicate that aerobic storage of energy sorghum biomass may be similar to other herbaceous feedstocks should extensive drying occur before entering storage
