    Notes: Drought is the major constraint limiting rainfed rice production. The ability of rice roots to penetrate compacted soils and therefore to increase water extraction capacity, osmotic adjustment and dehydration tolerance of leaves enables the plant to tolerate drought. Experiments were conducted to determine the extent of genetic variation in root penetration index, osmotic adjustment and dehydration tolerance among indica accessions adapted to rainfed lowlands as well as traditional varieties from rainfed uplands. Root penetration index was evaluated in a system using wax–petrolatum layers to simulate soil compaction. Osmotic adjustment and dehydration tolerance were studied under slow development of water stress. Substantial genetic variation was found for root penetration index, osmotic adjustment and dehydration tolerance among indica ecotypes from lowlands, and the study of several traditional varieties from uplands showed variation in root penetration index and related root traits. An indica accession, IR58821-23-B-1-2-1 had a high root penetration index of 0.38. The accessions, IR61079-33-1-2-2-3, IR62266-42-6-2 and IR63919-38-B-1 had high osmotic adjustment capacities (1.91, 1.90 and 1.78 MPa, respectively); IR61079-33-1-2-2-3 also had high dehydration tolerance. Good osmotic adjustment and dehydration tolerance were associated with poor root system. The traditional varieties ‘Kallurundaikar’ and ‘Norungan’ had higher root penetration indices (0.46 and 0.43, respectively), than even the japonica accessions. The study identified indica accessions and traditional varieties with superior root- and shoot-related drought resistance traits that could be used in breeding for drought resistance in rice.

    Notes: Abstract Rice varieties such as IR-20, Ponni, Bhavani and IR-50 that are preferred for cooking showed larger surface area, higher water uptake at 96°C, greater cooked volume, soft gel consistency and greater elongation ratio. Rice varieties which are exclusively used for makingidli anddosai exhibited lower protein content, medium alkali score and higher percentage of total as well as soluble starch and amylopectin. Rice varieties which are used for making flakes showed hard gel consistency, higher alkali digestibility values, lower soluble amylose content and relatively higher amount of hot water-soluble reducing sugars. Varieties used for making puffed rice do not show any specific characteristics to differentiate them from the above types. All the rice varieties studied belong to the high amylose group except ASD-1 which belongs to the medium amylose group.

    Notes: Abstract Since germination has been found to improve the nutritional quality of grains, sunflower seeds Helianthus annuus were germinated for up to five days, and the cotyledons were analyzed for oil, sugar, free amino acid, non-protein nitrogen, lysine, tryptophan and methionine contents. Protein was fractionated. Soaking and germination increased the non-protein nitrogen, total free amino acid, lysine and tryptophan contents. Protein content and dry weight decreased. The oil content decreased significantly after 72 hours of germination. The reducing sugars increased gradually until day ‘five’ of germination.The saline soluble albumin and globulin fractions decreased while the glutelin content increased during germination. No changes were noticed in the prolamin and methionine contents.

    Changes in the carbohydrates and nitrogenous components during germination of proso millet,Panicum miliaceum (1994)

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Since germination has been found to increase the nutritive qualities of grains, proso millet, a minor millet, was allowed to germinate for 1–7 days and analysed for protein fractions, free amino acids, lysine, tryptophan, methionine, non-protein nitrogen, starch, and sugars. Overnight soaking and germination up to 7 days significantly increased the free amino acids and total sugars while the content of dry weight and starch decreased. Increases in albumin and globulin and large decreases in prolamin accompanied sprouting. The percent protein in germinated grains was higher than in the initial grain as a result of dry matter loss during germination. Further, there was an increase in lysine, tryptophan and non-protein nitrogen contents during germination. No change was noticed in methionine content.

    Changes in starch, oil, protein and amino acids in developing seeds of okra (Abelmoschus esculentus L. Moench) (1987)

    Keywords: okra ; seed maturation ; protein ; oil ; starch

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract The okra seeds of variety Pusa sawani were analysed for protein, non-protein nitrogen, total free amino acids, lysine, and tryptophan from the 7th day to the 42nd day after flowering. Starch, total sugars and oil percent were also estimated in these seeds. During the early stages of maturation, the soluble components (non-protein nitrogen, free amino acids and total sugars) were found in higher quantities than in the later stages. Protein, oil and starch contents increased gradually from day 7 to day 42. The rate of accumulation of oil was found to be at the highest level between 21–28 days after flowering, while the rate of protein deposition was greatest between days 35–42. Inditiation of seed maturation seems to start 21 days after flowering in okra seeds.

    Changes in carbohydrate and nitrogenous components and amylase activities during germination of grain amaranth (1989)
    Springer

    ISSN: 1573-9104
    Keywords: grain amaranth ; germination α- and β-amylases ; lysine ; protein fractions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Grain amaranth (Amaranthus hypochondriacus), Yercaud local variety, was soaked overnight and germinated for 192 h taking the soaked grains as the zero time (0 h) sample. The changes in the activities of α- and β-amylases, starch, sugar, protein and lysine contents during germination are reported. Activity of α-amylase was high in the 0 h soaked grains, while β-amylase activity was high in 72 h germinated grains. The joint action of the amylases resulted in a decrease of starch content from 0 to 192 h in germinated grains and an increase in total sugars during the initial period of germination. Protein nitrogen was found to decrease from 48 h to 192 h accompanied by an increase in free amino acid and non-protein nitrogen contents. Total lysine content was found to be increased by 31% in 24 h germinated grain amaranth. Protein fractionation of raw, soaked and 24 h germinated grain amaranth showed that the distribution of different types of proteins varied during germination of the grains. An increase of water soluble protein content was noticed in 24 h germinated grains.

    Notes: Abstract Rice plant volatiles extracted as steam distillates significantly affected the behavior of the brown planthopperNilaparvata lugens (Stal). In a choice test, significantly more females settled and fed on tillers of a susceptible rice variety, Taichung Native 1 (TN 1), sprayed with acetone or untreated TN 1 plants than on TN 1 tillers sprayed with the extracts of resistant wild riceOryza officinalis. O. officinalis steam distillate was highly toxic to first-instar nymphs ofN. lugens. Ingestion and assimilation of food by females was significantly reduced on TN 1 plants sprayed withO. officinalis distillate compared to TN 1 plants sprayed with acetone. Application of0. officinalis distillate on TN 1 plants adversely affected hatchability of eggs ofN. lugens.
