ZM, "if such a stimulus is applied to one part of a plant, might the response be exhibited in only a part of the plant" Very likely, sometimes. However, there is considerable evidence of remote signaling. So, a stress in one part of a plant can trigger a response in other parts. Percy Wright, a Canadian plant breeder, told a story of how "His uncle moved from Saskatchewan had moved west to the Okanagan and for sentimental reasons had grafted some ultra hardy Saskatchewan plums onto a few branches of the peach trees in his orchard. A harsh test winter arrived after a few years which decimated not only the peach crop, but also the trees themselves. Most were killed outright or at the least severely injured. However the peach trees with ultra hardy Saskatchewan plums grafted in the branches had no winter damage whatsoever!" The environmental stress (cold? short days?) was detected by the ultra hardy plums, which then communicated an appropriate response -- presumably to the roots. When they went dormant, the rest of the tree had no choice but to follow. Here's a more recent example of remote signaling: Plant Mol Biol. 2003 Nov; 53(4): 493-511. Rootstock effects on gene expression patterns in apple tree scions. Jensen PJ, Rytter J, Detwiler EA, Travis JW, McNellis TW "Like many fruit trees, apple trees (Malus pumila) do not reproduce true-to-type from seed. Desirable cultivars are clonally propagated by grafting onto rootstocks that can alter the characteristics of the scion. For example, the M.7 EMLA rootstock is semi-dwarfing and reduces the susceptibility of the scion to Erwinia amylovora, the causal agent of fire blight disease. In contrast, the M.9 T337 rootstock is dwarfing and does not alter fire blight susceptibility of the scion. This study represents a comprehensive comparison of gene expression patterns in scions of the 'Gala' apple cultivar grafted to either M.7 EMLA or M.9 T337. Expression was determined by cDNA-AFLP coupled with silver staining of the gels. Scions grafted to the M.9 T337 rootstock showed higher expression of a number of photosynthesis-related, transcription/translation-related, and cell division-related genes, while scions grafted to the M.7 EMLA rootstock showed increased stress-related gene expression. The observed differences in gene expression showed a remarkable correlation with physiological differences between the two graft combinations. The roles that the differentially expressed genes might play in tree stature, stress tolerance, photosynthetic activity, fire blight resistance, and other differences conferred by the two rootstocks are discussed." The stress (fire blight infection) affected the scion, but the rootstock somehow mediated the response. You're right that stress "can encompass a wide range of factors, many of which we might not think of as 'stress'." To paraphrase Forest Gump, "Stress is as stress does." In the broad sense, any sort of change in conditions is stressful. Many kinds of environmental stress are easily tolerated and usefully exploited by plants (or animals) long accustomed to them. However, unfamiliar changes/conditions can provoke more profound disturbances. Changes in photoperiod, for example, are often exploited by plants to provide a trigger for flowering. But when certain plants (e.g., tropical) are exposed to the wide ranging photoperiods of northern regions, they may respond oddly. In its native habitat (Brazil) the beautiful Amaryllis fulgida (Hippeastrum striatum var. fulgidum) bears a cluster of 2-4 flowers on a scape around 18 inches tall. But when the species was first cultivated in Britain in the early 19th century, it changed dramatically. "This specimen was imported by Mr. Harrison, from Brazil, and was drawn at Aighburgh, April, 1832. Some of the leaves measured twenty-nine inches in length and nearly three in breadth; the first flower-stem (bearing eight flowers) attained the height of thirty inches, and would probably have become somewhat taller, but was generously cut for the completion of the present figure; a second scape immediately succeeded it, twenty-eight inches high and having six flowers." By the end of the century, the gigantism was gone. Generations of offspring from the original specimens soon became adapted to the British seasons and reverted to the original "type." Other differences in "stress" are obvious. I was thinking of various species of roses that tolerate very different conditions, and are also stressed by very different conditions. Forest species (e.g., Rosa pinetorum) are weakened by exposure to full sun, whereas R. arkansana thrives in full light. R. rugosa happily tolerates salt spray when grown near the ocean, while others are likely to be killed. Some favor in humus (woodland types) while others grow and flower best in sand. Furthermore, there are distinct "sensitive periods" (or "critical periods") in plant development. An environmental condition that is usually tolerated without much difficulty can become very stressful during a fairly brief period of transition. And one more item that I just found while looking for something else: Biosystems. 1995 ;36 (1):71-7 8527698 Adaptive determinism during salt-adaptation in Sorghum bicolor. H Seligmann , G N Amzallag During adaptation to salinity, plants of Sorghum bicolor showed malformations affecting the leaves in development (DPL). At the end of the adaptation process, the plants were regrouped according to their pattern of DPL response. The distribution of the plant population in different patterns depended on environmental conditions. However, a positive relationship between the frequency of a pattern and its rate of development has been found. Similarly, a negative relation between the frequency of a pattern and the rate of senescence for the same pattern has been observed. The results reveal the existence of an orientation of the plant response towards the patterns with highest developmental rate and lowest rate of senescence. This property is defined as "adaptive determinism". Results indicate that the NaCl acts as a trigger for adaptation to a whole range of environmental perturbations. This suggests that adaptation to salinity is not a pre-programed response of the plants, and may be related to learning processes occurring in animals. Amzallag made some very interesting studies of the effects of salt on sorghum. I just decided to make a bibliography of his papers.

I responded to one of the previous threads...just wanted to update. I purchased my knobs, pulls and appliance pulls from Knobshingesandmore.com. I got all of my kitchen stuff (top knobs is the manufacturer) in 2 weeks. I'm still waiting on a delivery for some pulls for my laundry room. They really seem to have good pricing and will price-match. They carry just about every manufacturer I can think of, so they probably have the odd-sized stuff. HTH!

This is where I ordered my pulls from ( not birdcage) and I know several others here used them and were pleased. Customer service and price were superb. I was hesitant because the price was so much lower that I ordered one from them and one from another vendor at like 4 times the price. The truth is that I got mixed up and could not figure out which was which. So.... the choice to spend $50 vs $199 was pretty easy for me. Here is a link that might be useful: yourhomesupply

You said the price on Amazon is high, but from what I see, it's going to be the cheapest. Why don't you say where you are seeing it cheaper so that we can say whether we know the site or not? When buying on Amazon, pay attention to the seller's rating. From a quick look, I see 3 sellers on Amazon for this item. They are all offering free delivery. Two of the sellers have 82% and 85% positive rating respectively, which is dismal. One has 100% rating, but not a high number (only 89 ratings). Or you could pay $100-150 more at reputable websites. Look, if you are going to choose Hafele, it'll cost you. Is $100 savings going to make or break you in the cost of your kitchen remodel? If you are nickeling and dimeing for $100, then Hafele is not for you.
