AbstractAbstract
[en] In the given article the influence of neutron radiation on energy of germination and viability of seeds corn has been studied and comparing them with control samples. The germination energy of seeds before and after irradiation have been estimated. It has been shown that at low doses of neutron irradiation, the germination energy of corn seeds is stimulated.

AbstractAbstract
[en] This paper is a result of the greenhouse experiments conducted on micronutrient studies in corn. Low yields of corn in some localities despite the application of major elements points out the need for examining the micro-nutrient requirements of corn. Hence, this study aims to determine the fate of added micronutrients on major soil groups with the application of varying levels of nitrogen, phosphorus, and potassium to provide the better understanding of soil micronutrients especially in problem soil. Three soil types, four N-P-K treatments and two micronutrients (Zn and Fe) were used. The test crop was a Tinigib corn variety and sampled at tasseling and silking stages. It was found that NPK combinations of 120-60-30 kg/ha and 60-30-30 kg/ha gave better Fe and Zn fertilizer use efficiency, respectively for a given soil type. Further investigation in major soil types is recommended. (Auth.) 12 refs.; 9 tabs

AbstractAbstract
[en] A transport velocity of Pu complexed with the siderophore DFOB has been measured in corn to be at least 174 cm/h. Based on a calculated plant water velocity, a Pu retardation factor of 1-10 was estimated. Dominant Pu species retardation in soil is typically several orders of magnitude higher than this, implying that plants can be a vector for exceptionally rapid upward Pu mobility. (author)

AbstractAbstract
[en] Eighteen hybrids and 13 open pollinated varieties of maize were evaluated at the National Agricultural Research Centre, Islamabad during kharif 2007. Significant differences were observed for days to 50% tasseling and silking, plant height, ear height, number of kernel rows per ear, number of grain per row, 100 grain weight. grain moisture and grain yield. The hybrids NT-6622 and NT-6651 ranked top and second in grain yield by producing 7842 and 7759 kg ha/sup -1/, respectively. Generally the hybrids produced more grain yield than the open pollinated varieties. Days to 50% tasseling ranged from 47.33 (EV-1098) to 64 (NT- 6632) while for silking varied from 47.67 (EV-1098) to 63.33 (30-K-95). The variety Soan-3 (149 cm) was the shortest and hybrid 30-K-95 (202.3 cm) was the tallest amongst all the varieties and hybrids. Ear height ranged from 70.33 (Soan-3) to 107 cm (NT-6651) while number of kernel rows per ear varied from 12 (NT-6622, 30- K95, 2512 and 2514) to 18 (R-2207). The hybrid P-30-25 produced the maximum number of grains (51) Grast-8288 produced the lowest (29). One hundred grain weight ranged from 23g (EV-6098) to 39g (2512). (author)

AbstractAbstract
[en] The paper presents the results of a study of the effect of presowing gamma irradiation in different doses on the functioning of antioxidant enzymes in maize and pea plants. It has been established that the control samples of these plants have different protective potentials and the presowing gamma irradiation affects the activity of antioxidant enzymes in different ways. In this case, the activity of enzymes besides the plant species also depends on the radiation dose

AbstractAbstract
[en] Shortage of irrigation water at critical growth stages of maize is limiting its production worldwide. Breeding drought-tolerant cultivars is one possible solution while identification of potential genotypes is crucial for genetic improvement. To assess genetic variation for seedling-stage drought tolerance, we tested 40 inbred lines in a completely randomized design under glasshouse conditions. From these, two contrasting inbred lines were used to develop six basic generations (P1, P2, F1, F2, BC1F1, BC2F2). These populations were then evaluated in a triplicated factorial randomized complete block design under non-stressed and drought-stressed conditions. For statistical analyses, a nested block design was employed to ignore the replication effects. Significant differences (p=0.01) were recorded among the genotypes for investigated seedling-traits. Absolute values of fresh root length, fresh root weight, and dry root weight lead to select two genotypes, one tolerant (WFTMS) and one susceptible (Q66). Estimates of heritability, genetic advance, and genotypic correlation coefficients were higher and significant for most of the seedling-traits. Generation variance analysis revealed additive gene action. Narrow-sense heritability [F2 = 65; F8 = 79] revealed the same results. Generation mean analysis signified additive genetic effects in the inheritance of cob girth, non-additive for plant height, grains per ear row and grain yield per plant, and environmental for ear leaf area, cob length, grain rows per ear, biomass per plant, and 100-grain weight under drought-stressed conditions. For conferring drought-tolerance in maize, breeders can adopt the recombinant breeding strategy to pyramid the desirable genes. (Author)
