Abstract Knowledge on the responses of guava to environmental factors such as light, temperature, water availability and CO2 concentration is essential to determine the effect of suboptimal environmental conditions and to manage the crop for maximum productivity. This chapter aims to highlight the current understanding and the possible effects of environmental factors on the whole physiology of guava trees as expressed by growth, yield, fruit quality and photosynthetic features. Possible areas of future research are also suggested.

Central Poland

There were 13 blackberry cultivars new in Poland tested, including: Black Butte, Boysenberry, Chester Thornless, Helen, Karaka Black, Kotata, Loch Ness, Loch Tay, Loganberry, and Oregon Thornless. The experiment was conducted between 2005 and 2010 in central Poland with the main focus on resistance of the cultivars to adverse local environmental conditions, as well as to assess the yield and fruit quality. Analysis of data on fruit yield and fruit weight indicated significant differences between cultivars and years. There were slight differences in harvest date from year to year. Cv. Chester Thornless had the greatest yield – avg. 12.9 kg/plant (2007–2008). All of the hybrid berries and the trailing blackberries had yields that were not different – below 3.5 kg/plant. Cvs Black Butte and Karaka Black had the heaviest fruit, above 6.0 g (2006) and up to 10 g per fruit (2007 and 2008). Cv. Oregon Thornless had the smallest fruits – 2.1 g per fruit (2006) and up to 3 g (2007, 2008). The experiment showed that plants were influenced by the Polish weather conditions.

The use of Sevin XLR Plus in chemical thinning applications at or shortly after petal fall in 1998 resulted in serious negative fruit quality effect, especially on `Red Delicious'. This negative fruit quality impact was worse in certain Henderson Co., N.C., orchards. Fruit diameter was reduced by 9%, fruit weight was reduced by 22%, misshapen fruit increased by 30%, eliminator fruit (<2.25″) increased by 102%, severely stunted fruit (<2.0″) increased by 317%. Surface russetting increased by 160% and seed numbers per fruit dropped by 27%. These are “never before seen” fruit quality problems for North Caronlina, which appear to be related to the unusual environmental conditions between full bloom and fruit thinning. Comparing the 30-year weather records, Apr. 1998 was the wettest April on record with twice the average rainfall. There were only two rain free days between bloom and petal fall, and only 9 of the 30 days following bloom were rain-free. Daily lows were at or above while daily highs were below the 30-year average, resulting in an extremely small daily temperature fluctuation. The departure from normal for average daily temperature was highly negative from partial petal fall until 2 weeks post petal fall. Daily relative humidity values for daily minimum, average and maximum were consistently and substantially above 30-year average values. It appears that these environmental extremes with Sevin XLR Plus use has an impact on fruit quality. In one `Golden Delicious' orchard where Sevin formulations could be compared side by side, fruit russetting jumped from 5.3% with 50 WP to 36.2% with the XLR Plus formulation.

Abstract: The objective of this work was to evaluate the vegetative and productive performance of plantain (Musa spp.) genotypes of the Terra subgroup under the environmental conditions of the Ribeira Valley in the state of São Paulo, Brazil. The experimental design was randomized complete blocks, with 12 genotypes and four replicates. Two types of genotypes were evaluated: six of the French plantain type, using the Maranhão cultivar as a reference; and six of the Horn plantain type, using the D’Angola cultivar as a reference. The treatments were evaluated during two production cycles, based on the following variables: pseudostem height and diameter, number of active leaves, total number of suckers and of plant cycles, fruit fresh mass, fruit length and diameter, fresh mass of the second hand, number of hands and of fruits in the bunch, bunch mass of marketable fruits, and productivity. Of the Horn plantain genotypes, 78 and 88 presented a better vegetative and productive performance, smaller plants, a larger pseudostem diameter, and a higher productivity than the D’Angola cultivar. None of the French plantain genotypes was superior to the Maranhão cultivar in terms of productivity and fruit quality. However, genotypes 79, 80, 82, and 84 present, as differential characteristics, a lower pseudostem height and a shorter total cycle, which could be explored to improve their productive potential.

In recent years, with electron microscopes coming into wider use, their installation environments do not necessarily give their performance full play. Their environmental conditions include air-conditioners, magnetic fields, and vibrations. We report a jointly developed entirely new vibration isolator which is effective against the vibrations transmitted from the floor.Conventionally, large-sized vibration isolators which need the digging of a pit have been used. These vibration isolators, however, are large present problems of installation and maintenance because of their large-size.Thus, we intended to make a vibration isolator which1) eliminates the need for changing the installation room2) eliminates the need of maintenance and3) are compact in size and easily installable.
