Luce t & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. were found to be associated with the seeds of 14 varieties viz. CB-1 to CB-14 of cotton. Seed quality analysis showed that percentage of pure seeds, germination, moisture, seedling mortality and associated fungi with different varieties of cotton seeds varies from 97.08-99.92%, 80-93%, 10-11.3%, 16.05-50.30% and 24-78.0% respectively. Present study deals with estimation of interrelationship between some quality factors through correlation and regression analysis are important for the assessment of seed quality. There were negative correlations between seedling mortality and purity percentage and between germination rate and fungus frequency. On the other hand, positive correlations were found between germination rate and purity percentage, between seedling mortality and fungus frequency, between purity percentage and fungus frequency, between germination rate and seed moisture and between fungus frequency and seed moisture. CB 8 was superior from the other cotton variety as it showed higher physical purity of seed (98.41%), higher seed germination (92%), lower fungal incidence (24%) and lower mortality of seedling (23.91%).

A pollen mixture from three male quaking aspen (Populus tremuloides Michx.) trees was irradiated at exposures of 484, 968, 1453, 1937, 3874, 7747, and 15 494 R and used to control-pollinate cut branches from three female trees. The pollen radiosensitivity was determined from various seed yield and seed quality factors. The pollen LD50 exposure varied with the end point evaluated, ranging from 255 R for number of 50-mesh seed per catkin to 8800 R for total seeds per catkin. The mean LD50 for nine seed yield and seed quality end points was 3995 R. A significant stimulatory response in seed yield was noted at low pollen irradiation levels, particularly at the 484-R exposure. The LD100 was approached but not reached at 15 494 R. Irradiated quaking aspen pollen may be useful in breeding experiments.

Abstract Florunner and Southern Runner peanut (Arachis hypogaea L.) cultivars were evaluated for yield, market grade and seed infections by Aspergillus spp. following treatment with fungicide programs for control of peanut leaf spot (Cercospora arachidicola Hori and Cercosporidium personatum (Berk. & M. A. Curtis) Deighton) in field trials during 1989 and 1991. The fungicide treatments were: 1) nonsprayed control; 2) chlorothalonil 1.26 kg a.i./ha (seven total applications); 3) the same as treatment no. two except tebuconazole 0.25 kg a.i./ha was substituted for chlorothalonil at applications three and five in 1989; and 4) the same as treatment no. three except cyproconazole 0.23 kg a.i./ha, was used instead of tebuconazole in 1991. Yield, grade ($/m.t.), and total crop value ($/ha) were higher for both cultivars when treated with chlorothalonil and either tebuconazole or cyproconazole than when chlorothalonil was used alone. Southern Runner had significantly lower percent damaged kernels (DK) than Florunner. In addition, Florunner peanuts treated with either tebuconazole or cyproconazole had significantly reduced DK when compared to chlorothalonil alone. Other market grade factors were not significantly different (P<0.05) between cultivars when each was harvested at optimum maturity. Major colonizers of damaged kernels were Aspergillus spp., Fusarium spp., and Rhizoctonia spp. Fungicide treatment and cultivar effects on kernel colonization by Aspergillus flavus Link: Fr. varied between environments. Southern Runner had higher levels of A. flavus contamination in the undamaged kernels than Florunner in 1991, but not in 1989. Possible increased incidence of infection and colonization by A. flavus in Southern Runner require further study.

Cucumber seeds were taken to assess the effect of temporal variation on the seed quality. Seeds were stored in three types of containers, such as metal (tin), polythene bag, and cloth bag. The containers were stored at room temperature and ambient relative humidity around three months. Seed quality factors viz., moisture content, germination percentage, vigor index, percentage of abnormal seedling, fresh seed, dead seed, hard seed, root-shoot ratio and amount of dry matter were recorded every 15 days interval. The initial moisture content of seed in tin, poly bag, and cloth bag were 10.66%, 10.13%, and 9.89%, respectively, but it was increased with increasing storage time after 60 days (11.08%, 10.67%, and 10.98%). The germination percentage was higher at 15 days after observation (DAO) for different containers like tin (90%), poly bag (86%), and cloth bag (85%) than after 60 DAO (86%, 84%, and 80%), respectively, on blotting paper substrate. The percentage of dead seed was increased from 2 to 10%, 5 to 12%, and 6 to 12% in tin container, poly bag, and cloth bag, respectively, from 15 DAO to 60 DAO. The vigor indexes of seedling were 14.58, 12.85, and 10.92 at 15 DAO in tin, poly bag, and cloth bag, respectively, which attained at 10.39, 10.26, and 10.08 at 60 DAO, respectively. The length of seedling was 25.85 cm, 25.15 cm, and 24.30 cm at 60 DAO in tin, poly bag, and cloth bag, respectively. Shoot-root ratio was found highest in tin container at 15 DAO (0.95) and lowest in cloth bag (0.70) at 60 DAO. Key Words: Seed quality, cucumber, temporal variation, biotic and abiotic factors.

The Relationship

A two-year study considered the effect of pod harvesting intervals of 3, 5, 7, 9, 11 or 20 weeks after pod set (WAPS) on the relationship between the physical condition of the pods, seed maturation and quality in fluted pumpkin (Telfairia occidentalis). Pod characteristics, such as the intensity of bloom wax on the pod and stiffness of the pod ridges, showed perfect linearity and correlation with the age of the pod, whereas changes in seed quality factors – germination, dry matter, oil and protein concentrations were curvilinearly associated with the time of pod harvest. Thus, seed quality factors increased steadily up to nine WAPS then declined. The point at nine WAPS defined as physiological maturity for fluted pumpkin seed and approximate visible indications of this point in the field were fairly stiff pod ridge condition and fading of bloom wax.

Healthy Seed

The potato yield, planned on the basis of calculated methods of fertilizer application, in practice can fluctuate over a wide range. Many factors influence the increase in the removal of nutrients and potato yields. One of the most important factors for potatoes, as a vegetatively propagated culture, is the quality of the seed material. The purpose of the research was to substantiate the algorithm for obtaining high potato yields on the basis of determining the influence on the productivity of quality factors of seed material, the background of fertilizers, irrigation, the use of chemical etchant and biologically active preparations. Experiments of Kortni and Nevskiy varieties were conducted in Laishevsky district of the Republic of Tatarstan. It was revealed that in gray forest soils under experimental conditions, the optimal background of fertilizers with the main application on the bog was N120P140K140, on irrigation - N100P120K120. Higher doses of fertilizers on irrigation and on the bog caused lower yields. The use of the Maksim chemical preservative on the bog in the arid conditions of the year increased productivity by 6.0 ... 12.0%, on irrigation - reduced by 18.0 ... 24.6%. Biologically active preparations increased productivity in moist soil by 14.0 ... 17.0%. The consistent increase in the yield of a healthy seed of Kortni variety occurred under the influence of factors: the quality of seed material - from 10 to 15.5 tons per hectare - by 55%, the background of fertilizers N100P120K120- from 15.5 to 26.3 tons per hectare - by 70% irrigation - from 26.3 to 54.0 tons per hectare - by 105.3%, treatment with zircon - from 54.0 to 61.5 tons per hectare - by 14%. Against the backdrop nutrition of N100P120K120, calculated to yield of 20 tons per hectare, with additional factors, a yield of 61.5 tons per hectare (+ 208%) was obtained. In the degenerate seed material of Nevskiy variety, the increase in productivity with the progressive use of factors occurred to a much lesser extent: from the quality of the seed material - from 10.0 to 12.0 tons per hectare - by 20%, the fertilizer background N100P120K120 - from 12 to 17.5 tons per hectare - by 46%, irrigation - from 17.5 to 23 tons per hectare by 31.4%. Against the nutrition backdrop of N100P120K120, calculated to yield of 20 tons per hectare, Nevskiy yielded 23 tons per hectare (+ 15%). The importance of seed quality is a key in obtaining high yields of potatoes. In healthy seed potatoes, with additional factors - irrigation, fertilizers, BAP - much higher yields are created, compared to the addition of the degenerate seed material under the same conditions. On the basis of the obtained results, the following algorithm for applying the factors for obtaining high potato productivity is recommended: healthy seeds + irrigation + fertilizers + biologics.

Health And Well Being

A high-quality diet is one of the foundations of health and well-being. For a long time in human history, diet was chiefly a source of energy and macronutrients meant to still hunger and give the strength for work and activities that were in general much harder than nowadays. Only few persons could afford to emphasize enjoyment. In the assessment of quality, organoleptic properties were major criteria to detect spoilage and oxidative deterioration of food. Today, food hygiene is a quality aspect that is often taken for granted by consumers, despite its lack being at the origin of most food-borne diseases. The discovery of micronutrients entailed fundamental changes of the concept of diet quality. However, non-essential food components with additional health functions were still barely known or not considered important until recently. With the high burden of obesity and its associated diseases on the rise, affluent, industrialized countries have developed an increased interest in these substances, which has led to the development of functional foods to optimize special body functions, reduce disease risk, or even contribute to therapeutic approaches. Indeed, nowadays, high contents of energy, fat, and sugar are factors associated with a lower quality of food, and products with reduced amounts of these components are valued by many consumers. At the same time, enjoyment and convenience are important quality factors, presenting food manufacturers with the dilemma of reconciling low fat content and applicability with good taste and appealing appearance. Functional foods offer an approach to address this challenge. Deeper insights into nutrient-gene interactions may enable personalized nutrition adapted to the special needs of individuals. However, so far, a varied healthy diet remains the best basis for health and well-being.

New Cultivars

Some characteristics of seed quality, establishment rates, performance in mixtures and response to grazing management of 5 new pasture plants with potential in dryland are described. On a dry hill country site in the Wairarapa, the contribution of the sown grasses established in separate plots with clovers under rotational grazing was 'Grasslands Wana' cocksfoot 65%; 'Grasslands Maru' phalaris 23%; 'Grasslands Matua' prairie grass 22%; and 'Grasslands Roa' tall fescue 13% after 2 years. The other main grass species was resident perennial ryegrass which established from buried seed (ca. 240 plants/m*) and had a major impact on the establishment and growth of the sown grasses. On a seasonally dry Manawatu flat land soil 3 grazing managementsviz. set stocked all year (S); rotational all year (R); and combination (Cl (set stocked from lambing to drafting and rotational for the remainder of the year) were applied to mixtures of the new cultivars (except that 'Grasslands Apanui' cocksfoot replaced Wana) with ryegrass and white clover stocked at 20 sheep/ha. After 3 years the contribution of the new cultivars was negligible under S and ryegrass was dominant. The R pastures became cocksfoot dominant and Matua (in winter) and chicory (in summer) contributed more than in the S system. The C system produced the most evenly balanced species contribution with only Roa remaining at (5%. A sub-trial with cocksfoot cultivars demonstrated that Wana maintained better production and tiller density ~ll,000/m2 ) than Apanui (1000/m' ) under set stocking IS). Although some of the new cultivars will require specialised management procedures to fulfil their potential in dryland, the increasing and widespread use of Matua prairie grass in farming suggests that these techniques can be adopted in commercial agriculture provided good technical information is available in a management package when the cultivar is released.
