When there is no security manager, there is no change to existing behavior the property can be set to true: =true or false. If a security manager is set, such as in WebStart applications, double-quotes are encoded as described. An argument containing double-quotes, other than first and last, is encoded to preserve the double-quotes when passed to the process previously, the embedded double-quotes would be dropped and not passed to the process. An empty argument is encoded as a pair of double-quotes ("") resulting in a zero length string passed for the argument to the process previously, it was silently ignored. An argument with a final trailing double-quote preceded by a backslash is encoded as a literal double-quote previously, the argument including the double-quote would be joined with the next argument. In the implementation on Windows, the system property =false ensures, for each argument, that double-quotes are properly encoded in the command string passed to Windows CreateProcess.

Apple and pear trees with several severely infected shoots appear scorched by fire (Figure 4-156). The infected shoots form an "inverted J" or a shepherds' crook at the tip (Figure 4-155) - often the first symptoms are observed several weeks after bloom. As the bacteria move down the shoot, stem tissues become discoloured and shriveled. The bacteria move 15-30 cm or more in the shoot within a few days after infection. Injuries on leaves and shoots caused by sand blasting, wind whipping or hail provide an entrance for the bacteria into the susceptible tissue. Shoot blight symptoms are observed throughout the spring and summer seasons, especially when fire blight is present in the orchard in infected blossoms, other blighted shoots and overwintering cankers. Shoot blight develops very quickly once infection takes place. Infected shoots first appear water-soaked but quickly turn brown or black. Succulent shoots and suckers (water sprouts) can also become infected resulting in shoot blight. Infected blooms first appear water soaked and later begin to wilt, shrivel and turn brown or black Shoot blight If the spur on a main branch or the trunk becomes infected, the disease can move from the spur into the trunk or branch eventually developing into a canker which girdles the branch or limb.įigure 4-154. Once blooms are infected, blossom blight frequently remains attached to the tree allowing the disease to progress into the flower stem and then into the spur. Pollinating insects visiting contaminated flowers spread the disease to non-infected flowers. Infected blooms first appear water soaked and later begin to wilt, shrivel and turn brown or black (Figure 4-154). Blossom blightīlossom blight is observed in the spring when flowers are infected. Severely infected trees with fire blight appear to be "scorched" by fire Symptomsįire blight attacks many different parts of the tree, and fire blight symptoms are often referred to the part of the tree attacked - blossom, shoot, fruit, limb and trunk, and collar or rootstock blight. Fire blight has become a serious problem in high density apple plantings that contain new susceptible varieties and dwarfing rootstocks (Figure 4-153).įigure 4-153. The pathogen has caused most damage in southwestern Ontario, where, in some years, whole orchard blocks have been destroyed due to severe infections. amylovora is found in most areas of the province where apples are grown. Raspberry can be infected by fire blight bacteria, but the raspberry strain cannot infect apple, pear or ornamental plants. The host plants include quince, crab apple, hawthorn, cotoneaster, mountain ash and firethorn. The disease is caused by a bacterium, Erwinia amylovora (Burrill), which infects hosts in the Rosaeceae family. Fire blight is a serious disease causing considerable damage and economic losses in apple and pear. Find the best deals on HP 564 and HP 564XL ink cartridges at the official HP Canada Store.

Therefore, the IZW scientists and their zoo colleagues thoroughly monitored the Achilles heel of the reproduction cycle, the parturition. "Even though the birth of a live calf is particularly important in species with long reproduction cycles, there have been no data available that allow the prediction of physiological events during normal parturition in rhinoceros." "Birth and perinatal period represent the eye of the needle of the reproductive cycle to establish a new generation and to secure the long term survival of all rhino species," says rhino specialist Prof Robert Hermes from the Leibniz-IZW's Department of Reproduction Management. Delivering a live and healthy calf is of key importance to ensure that the resources the female invested are not lost in the very last minute. The reproduction cycle in rhinos covers 4 to 6 weeks of oestrous cycle, about 16 months gestation and up to 6 months of lactation, summing up to a total of 1.5 to 2.5 years - one of the longest reproduction cycles in terrestrial mammals. The reproductive investment of slow reproducing species such as the rhinoceros is tremendous. The results are published in the scientific journal Theriogenology. These data significantly improves the knowledge base for birth management and obstetrics in rhinos and will help to reduce the number of stillbirths or perinatal problems in zoological gardens. Scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) together with zoo veterinarians closely monitored 19 pregnant white rhinos in six European zoos and recorded timelines for pre-birth development, milk production, hormone levels, gestation length and documented the onset of parturition, different stages of labour and foetal position at birth. When exactly is a rhino offspring born? How long does the birth actually take? Does parturition proceed normally? Answers to these and similar questions are difficult for experts in zoological gardens, since baseline knowledge of the reproduction cycle of all rhinoceros species, especially its final stage, the parturition, is scarce.
