Fruits for the family

Strawberries, plums, currants and gooseberries can be grown in all parts of the state. Red and black raspberries, though equally distributed regionally, are capricious in their reaction to soils, water supply and diseases. They may be a success on one piece of ground and a failure on the one adjoining. Grapes are well adapted to central and southern Iowa and they withstand considerable abuse and still yield some fruit nearly every year. Plums are the most widely adapted and apples the most popular fruits in the home orchard, but only hardy varieties resistant to disease should be planted. They must, along with the rest of the fruit garden, be protected from farm animals and cared for properly after planting, if they are to be successful. The common red cherries and two or three varieties of hardy pears should be included in home orchards in the south half of the state. Peach, nectarine, apricot and quince cannot be recommended as dependable for long life or production in any section, but many people will want to plant a few of them and be satisfied with an occasional crop

Save Those Vegetables

In our effort to conserve food at home this year, the storage of vegetables is exceedingly important. Potatoes, carrots, beets, parsnips, cabbage, onions, squash, pumpkins and other vegetables can be stored successfully over winter so that they remain fresh and firm. The more vegetables that can be stored fresh, the less the family need draw upon canned, frozen and other conserved foods

Grape training and pruning in Iowa

The Concord grape and grapes of this type and hardiness, which are the grapes most widely grown in Iowa, require yearly pruning if the grower wishes to obtain heavy annual yields of large-sized high-quality fruit. The illustration on the cover of this bulletin indicates the development and distribution of the fruit which may be expected on correctly pruned vines. Far too many home vineyards are left unpruned or are incorrectly pruned with the result that they are unproductive and unsightly. There are many systems used in training the American grape, but the system which seems to be best adapted to Iowa conditions is the single-stem four-cane Kniffin system. The spur method of pruning, which has been employed to a considerable extent with the European grape, is still followed in many sections of Iowa. Unfortunately, this method is unsatisfactory with the Concord grape and, except with grapes trained on arbors, should not be used. The grapevines pruned by the long cane method and trained to the Kniffin system in certain Iowa tests have repeatedly out-produced those pruned by the spur method. The Concord produces the heaviest yield of fruit from approximately the fifth to ninth bud and the lowest yield from the first four buds on the cane. Therefore, it can be seen that with the spur method of pruning, when only the first two buds are left on each cane, the heaviest producing buds are removed. The characteristic bearing habit of the American grape explains why long cane pruning is more productive than the spur cane system

Are language production problems apparent in adults who no longer meet diagnostic criteria for attention-deficit/hyperactivity disorder?

In this study, we examined sentence production in a sample of adults (N = 21) who had had attention-deficit/hyperactivity disorder (ADHD) as children, but as adults no longer met DSM-IV diagnostic criteria (APA, 2000). This “remitted” group was assessed on a sentence production task. On each trial, participants saw two objects and a verb. Their task was to construct a sentence using the objects as arguments of the verb. Results showed more ungrammatical and disfluent utterances with one particular type of verb (i.e., participle). In a second set of analyses, we compared the remitted group to both control participants and a “persistent” group, who had ADHD as children and as adults. Results showed that remitters were more likely to produce ungrammatical utterances and to make repair disfluencies compared to controls, and they patterned more similarly to ADHD participants. Conclusions focus on language output in remitted ADHD, and the role of executive functions in language production

SPATIOTEMPORAL REORGANIZATION OF GROWTH RATES IN THE EVOLUTION OF ONTOGENY

Heterochrony, evolutionary changes in rate or timing of development producing parallelism between ontogeny and phylogeny, is viewed as the most common type of evolutionary change in development. Alternative hypotheses such as heterotopy, evolutionary change in the spatial patterning of development, are rarely entertained. We examine the evidence for heterochrony and heterotopy in the evolution of body shape in two clades of piranhas. One of these is the sole case of heterochrony previously reported in the group; the others were previously interpreted as cases of heterotopy. To compare ontogenies of shape, we computed ontogenetic trajectories of shape by multivariate regression of geometric shape variables (i.e., partial warp scores and shape coordinates) on centroid size. Rates of development relative to developmental age and angles between the trajectories were compared statistically. We found a significant difference in developmental rate between species of Serrasalmus , suggesting that heterochrony is a partial explanation for the evolution of body shape, but we also found a significant difference between their ontogenetic transformations; the direction of the difference between them suggests that heterotopy also plays a role in this group. In Pygocentrus we found no difference in developmental rate among species, but we did find a difference in the ontogenies, suggesting that heterotopy, but not heterochrony, is the developmental basis for shape diversification in this group. The prevalence of heterotopy as a source of evolutionary novelty remains largely unexplored and will not become clear until the search for developmental explanations looks beyond heterochrony.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72102/1/j.0014-3820.2000.tb00568.x.pd
