Early Seedling Development

The response of onion (Allium cepa L.) to postemergence applications of oxyfluorfen during early seedling development was measured in growth room experiments. Tolerance to oxyfluorfen increased more than 70-fold from the late loop to the two fully developed leaf stage. Field and growth room experiments were also conducted to determine the relationship of spray retention and epicuticular wax on the tolerance of onion seedlings to the herbicide. In general, there was a progressive decrease in spray retention and a corresponding increase in epicuticular wax per unit dry weight as plant age increased. Spray retention in the field was approximately twice as great as in the growth room. The amount of epicuticular wax on the leaf surfaces of the onions was about equivalent under the two growing conditions. A significant decrease in epicuticular wax per unit dry weight between the late one-leaf and late two-leaf stages occurred under both field and growth room conditions, while tolerance to the herbicide continued to increase during the same period.Key words: Onions, oxyfluorfen, ED50, spray retention, epicuticular wax

The Relationship

The article deals with gnosis and features of metacognition. Initially, the Gnostics considered whether the term "gnosis" was used, what knowledge did they gain from certain experiences. The subject matter of the study reveals important features of the human psyche. For example, the property of separating one’s self from the external environment is like seeing oneself from the side. This property empowers a person in communicating with other people. This expanded opportunity purifies the human being, because it leads to self-control. During vegetable growing, conditions of a special nature can be experienced by themselves. The Gnostics also spoke about it.The article states that the philosophy of gnosis operates through belief in the special inner world of man, the higher world. But this higher can only be felt when a person is in a state of enstasis as a compensatory trance.The article compares the gnosis of the ancient world with modern philosophical trends. Here, in the descriptions of the inner world of man, the divine transcendence is demonstrated. In this regard, the Gnostics sought knowledge of the true state of mind. This search is engaged in metacognition.The author of the article considers it necessary to clarify what metacognition is. A person has the ability to understand what he or she is thinking. Scientists call it metacognition. Metacognition is when a person feels the world not through the prism of his thoughts, but directly. We can also see this in Gnostics with deep compensatory enstasis, or compensatory trance. Then the person stands apart, because it breaks all the wrong connections. Gnosis tries to capture the knowledge of all these processes. Metacognition helps to establish certain characteristics of compensatory trance, to establish characteristics of compensatory illumination. Compensatory illumination may occur in a state of a particular type of trance. Therefore, the article tries to look at the relationship of compensatory trance and compensatory illumination.

Experiments were conducted in the field and greenhouse to evaluate the effects of cultivar and sulfentrazone rate on soybean injury and yield from soil-applied sulfentrazone and to determine soybean inheritance of sulfentrazone tolerance. Excessive rainfall and cool growing conditions in 1996 enhanced sulfentrazone injury and caused yield reduction in the susceptible cultivars ‘KS4895’ and ‘Hutcheson’ at 0.56 kg ai ha−1and KS4895 at 0.42 kg ha−1. Yields of tolerant cultivars ‘Deltapine 3478’ and ‘Manokin’ were not reduced. Sulfentrazone at 0.42 kg ha−1reduced soybean stand 17 and 35% for tolerant and susceptible cultivars, respectively. Field and greenhouse inheritance studies were conducted on plant families developed from two crosses: Manokin (tolerant) by ‘Asgrow A4715’ (susceptible) and ‘Northrup King S59–60’ (tolerant) by KS4895 (susceptible). The sulfentrazone tolerance of Manokin and Northrup King S59–60 appeared to be controlled by a single gene, with tolerance being dominant to susceptibility. The allelic relationship of tolerance from these two sources needs to be determined.

The practice of growing agricultural crops in rows results in larger soil nematode populations in the root-associated soil than in the bulk soil between the rows. Fertilisers applied to improve grain yield generally increase the abundance of nematode communities in agricultural soils. The objective of this study was to compare total nematode density and four dominant genera in the root-associated and bulk soils of paddy rice and upland wheat receiving organic and mineral fertilisers. Dominant nematode genera accounted for 80% of all nematodes and represented four trophic groups. There was greater total nematode density and a higher enrichment index (EI) but less nematode diversity (H′) and a lower structure index (SI) in the root-associated soil than bulk soil of upland wheat. By contrast, nematode abundance, diversity and ecological indices were similar in the root-associated and bulk soils of the paddy rice. Soil nematode communities were affected significantly and consistently by fertilisation in upland wheat and paddy rice phases. More herbivoreHirschmanniellawere present with mineral fertiliser than in the non-fertilised control. Straw-based organic fertilisers increased the abundance of bacterivoreEucephalobus. The lack of interaction between rhizosphere effect and fertilisation indicated that crop-growing conditions (different species and water regimes) were more influential on nematode communities and not consistently impacted by short-term organic and mineral fertilisation in the rice-wheat agroecosystem.

The Relationship

A survey has been made of the structure of the wood of Eucalyptusgigantea Hook. f. in relation to growing conditions in the Australian CapitalTerritory. Using the number of cells cut off by the cambium at various intervalsduring the growing season as a measure of growth, mathematical expressionshave been obtained for growth in young trees at ground level, breast height,.and half height; from these, growth rate curves have been derived. The timeof year at which growth commences, the relationship of vessel production tocommencement of growth, the formation of late wood, and the period of dormancyhave all been considered in detail. Variations in fibre dimensions havebeen investigated in relation to growth and it has been shown that in anyonegrowth ring the shortest fibres are found in the early wood and the longest inthe late wood. An intrinsic relationship between growth rate and fibre dimensions�has been established, and, at the junction between late and early wood, asudden change in fibre dimensions occurs corresponding to the discontinuity ingrowth rates. Anomalous woody tissue formed during severe drought conditionsis also described.

The Relationship

Nine (9) sites with different growing conditions used in the Regional Testing of Promising Coconut Hybrids and Cultivars in the Philippines or MULTILOC Project (1985‑1996) was subjected to the Crop Fertilizer Use Efficiency (CFE) Analysis. Two CFE indices were used CFEn = nut yield/kg fertilizer applied (per tree) and CFE X = kg copra yield kg fertilizers applied (per tree).   To a great extent, crop fertilizer use efficiency (CFE) ofsuperior hybrids grown in similar environments and appied with same moderate rates offertilizers have higher efficiency of converting the appliedfertilizers to economic yield, nuts or copra (measured in terms of CFEn and CFEc) compared to tall varielies tested in all MULTILOC sites (dry, intermediate and wet growing zone) at n ine years ftom field‑planting (FP). The CFEs, CFEn (nut‑based) at nine sites clearly differed in ternu of the first (best) five entries with highest CFE values. Explanation for this observation deserves further study, looking into the relationship of hybrid vigour (heterosis), crop morphology, physiology and yield.

The rate of water loss (RWL) from excised leaves has been proposed as a screening technique to identify wheat genotypes adapted to dry growing conditions. The relationship of RWL and grain yield was studied in 100 durum wheat (Triticum turgidum L. var. durum) genotypes grown at two locations in Canada and three locations in Syria. Fifty of the genotypes were chosen on the basis of low RWL and 50 on the basis of high RWL. Growing season precipitation ranged from 73 to 356 mm. Genotypes with low RWL yielded more than those with high RWL in four of the five driest environments in nine site-years of study. Yield of the low RWL genotypes ranged from 40 to 150% greater than that of the high RWL genotypes at the four sites. The high RWL group did not yield more than the low RWL group (P < 0.05) in any of the site-years. Glaucousness confounded interpretation of the results, since the low RWL group tended to be more glaucous than the high RWL group. Separation of the genotypes into high and low glaucousness groups showed that the high group yielded more than the low group in the three driest Canadian sites and in the wettest site in Syria. Low RWL and high glaucousness were associated with delayed leaf senescence in dry environments. It was concluded that low RWL contributes to high yield under dry growing conditions, and does not exhibit a metabolic carbon cost under more favorable precipitation regimes.Key words: Cuticular transpiration, Triticum turgidum L. var. durum, glaucousness, leaf senescence
