51) INVESTIGATION ON CULTIVATION OF THE OYSTER MUSHROOM (Pleurotus sp) ON DIFFERENT SUBSTRATES

Year /Number: 1994/2-167                             ODC :282.2:176.1 
Authors: ULUER, K., OZAY, F. S.

It has been aim to determine the effect of different substrates on the yield of Pleurotus sp. P. ostreatus and P. florida were inoculated and grown on logs of deciduous trees (Quercus cerris L., Fagus orientalis Lipsky, Populus tremula L., Alnus glutinosa (L) Gaertn, Tilia tomentosa Monench., Ulmus montana With., Castanea sativa Mill, Carpinus betulus L., Eucalyptus camaldulensis Dehm., Acer campestre (L.). The highest biological yield ratio (l8.29 %) was obtained from P. florida on Populus tremula L. P. ostreatus and P. florida were inoculated on stumps of poplar (Populus euramericana cv. O-214). Polyethylene plastic sheet, paraffin was and meadow were used to cover the stumps during incubation. The meadow was found as the best covering matter for incubation. The biological yield ratio obtained from this system was % 55.54. Five strains of Pleurotus (P. ostreatus, P. florida, P. sajor - caju, P. pulmonarius, P. columbinus) were grown on three substrates (Nutshell and cupula of Cryllus, arboreal wood of Rhododendron). The biological yield ration were found as 34.80 % on cupula of coryllus with P. ostreatus and 8.76 % on nutshell of coryllus qith P. sajor - caju. The fruitbody could not be obtained from the substrate of arboreal.


52) THE CONTROL MEASURES AGAINST Cryptorhynchus lapathi L.

Year /Number:1995/2-172                             ODC:145.7:19.91:176.1 Populus 
Authors: GULER, N., CAN, P., OZAY, F.

Cryptorhynchus lapathi L. cause des degats graves dans les pepinieres et dans les jeunes plantations de peupliers. La faculte de deplacement des adultes de C. lapathi est tres limitee et ne possede pas une grande aptitude a la dispersion. Mais les plants qui portent ses larves se transportent d'une region a l'autre, a cause de la difficulte d'identification de son existance C'est ainsi que son aire de repartition est en cours d'extention.C. lapathi etant une espece plalstique, peut montrer une large adaptation dans des secteurs bioclimatiques tres divers. D'autre part, la presence des larves ne se distingue que lorsque la galerie commence a penetrer dans le bois et qu'on apercoit de petits amas de dechets et de seve sur l'ecorco et par consequent on n'a pas la possibilite de faire les traitements chimiques a temps. Tandis que, pour obtenir des resultats satisfaisants avec la lutte chimique on doit identifier la periode optimum selon les conditions ecologiques de la region donnee.


53) PROBLEM OF Sciapteron tabaniformis Rott. IN POPLAR NURSERIES

Year /Number: 1995/3-173                             ODC : 145.7 :411.12 :414.1 :176.1 Populus 
Authors: GULER, N., CAN, P.

Sciapteron (=Paranthrene) tabaniformis Rott. Existe dans toutes les regions et cause des degats dans les pepinieres de peuplier, en Turquie. Les blessures pour quelque cause que ce soit, sur les troncs favorisint l'attaques de S. tabaniformis. Dans le cas d'attaque intensive, on doit faire appel a des traitements chimiques. Les observations faites en pepiniere de Behicbey (Ankara) et de Diyarbakir sur la susceptibilite de clones a S.tabaniformis ont montre que dans les memes conditions ecologiques d'une pepiniere, il est possible d'observes des degres differents d'attaque sur des clones se trouvant a proximite immediat les uns des autres. D'autre part, dans les conditions locales des pepinieres de Diyarbakir et Behicbey (Ankara) nous n'avons par trouve une correlation entre le diametre, la hauteur, la forme des plants de divers clones et l'intensite d'attaque. Un clone quelconque attaque massivement dans une pepiniere peup croitre sans souffre de S. tabaniformis dans un'autre. C'est pourquoi, il est necessaire de faire des experiences locales pour determiner la sensibilite d'un clone donne aux attaques de S. tabaniformis.


54) THE HARMFUL INSECTS ON WILLOWS IN MARMARA REGION IN TURKEY

Year /Number: 1997/4-183                             ODC: 245.1:145.11:245.12:245.13 
Author : OZAY, F.

Willows have been traditionally cultivated on the borders of fields and on the stream banks since the ancient times. It's wood have been used both as construction wood and fuel. Parallel to the increase on the demand for wood, willow plantations on large areas have been in practice like as of poplar cultivation. In recent years, several experiments are being performed considering willow cultivation. In this study, the harmful insects which attack on the native or exotic willows in Marmara region have been determined. The ecological conditions which increase the effect of insect damages have also been determined. As a conclusion, 66 insect species which attack on willows in Marmara region belonging to 28 different families and 5 order have been identified.


55) INVESTIGATION INTO PREVENTATION AGAINST DISEASE CAUSED BY Cytospora chrysosperma (Pers) Fr. IN POPLARS

Year /Number: 1998/3-186                             ODC: 172.8:411.16:416.4:181.29:176.1 Populus 
Authors: ULUER, K. GURER, M., GULER, N.

In this study, the susceptibility level of eighr poplar clones in response to Cytospora chrysosperma (Pers.)Fr. Is determined 77/10, Samsun and 67/1 are the lessast susceptible ones. I-214, Anadolu, and 64/13are revealed the most resistend ones. In the autumn plantations and inolulations, the cancer expansion is much higher than the one in the sipring. 2 years old sapling planted and inoculated in sipring are the least affected ones. The damages of fungus increases with the increase of winter injury, the rate of clay and lime and the damage decreases with the increase in the effectiveness of rain (1m). Fungus does the greates damage to the close planted saplings. Disease severity is high for the first year. The damage of fungus decreases in the second and following years.


56) INVESTIGATION ON Pygaera anastomosis L. WHICH IS HARMFULL ON POPLARS

Year /Number:2000/1-191                             ODC: 245.1:145.7:151.4:176.1.Populus 
Authors: OZAY, F., GULER, N.,ULUER,K., SELEK, F.

Pygaera anastomosis L. was found out at Bursa, Izmit, Sakarya, Edirne, Samsun-Bafra and damaged on Populus sp. and Salix sp. The insect has four generation per year in Bursa and Izmit . Stage of larva period lasts 18-20 days for 1,2,3. generations, and 240-245 days for 4. generation which hibernates. The metamorphosis of pupa lasts 7-12 days for 1,2,3th generations, 12-15 days for the 4th. Last generation's larvae spin a cocoon and hibernate into bark cracks of braches and injuried places. The copulation time of adults is about 8-15 hours. After 2-3 days of copulation, a female lays average 350-650 eggs. The embrional development lasts about 3-5 days. The larva molts five instar until being pupa and measures 30-32 mm when mature. The first and second instar larvae are gregarious leaf skeletonizers. The succesive instar larvae consume all the leaf tissues.


57) The determination of causes of insufficent growing and death in urban afforestration in Izmit

Year /Number:2005/200                             ODC: 279: 425.9: 449: 453: 469 
Authors: GULER, N., ULUER,K., OZAY, F., ZENGIN, M., SELEK, F.

The aim of this study is to determine the influence of a range of factors, including altitude, exposition, slope, soil conditions, traffic pollution and other biotic and abiotic hazards on the health of trees in İzmit. The most resilient tree species will be selected for inclusion in the city’s future afforestation programmes.


58) Investigation on the resistance of some poplar clones to the rust fungi (Melampsora allii-populina Kleb.)

Year / No.: 2008/207                          ODC: 172.8:411.16:416.4:176.1: Populus
Autors: ULUER, K., ÖZAY, F. Ş., SELEK, F., KARAKAYA, A.

This study was carried out the sensitivity of the P.x euromaricana (I-214) and P. deltoides clones [45/51, 77/51 (Samsun), S 307.26 (İzmit) and 89 M060], which are important in poplar growing in Turkey, against Melampsora allii-populina rust fungi.
According to the results of analysis of variance, there are significant difference between clones toward the rust fungi, but it wasn’t determined significant difference between space- distance and rust fungi. According to Duncan test, the 89 M 060 clone is the very resistant, the 45/51 and S.307.26 (İzmit) clones are resistant, the 77/51 (Samsun) and I-214 clones are sensitive toward the rust fungi.
