Abstract

This study was carried out to study the effect of insect infestation by Macrosiphum rosae L.on the vase life period on the rose flowers under greenhouse conditions at two locations International Garden (Cairo Governorate) and El-Orman Garden, (Giza Governorate) under glasshouse conditions during successive seasons 2018. This is because vase life period is a very important parameter in cut flowers. And there are many factors affected on the vase life period. Therefore this study divided into two parts, first part studied the effect of insect infestation by M. rosae on the vase life period of rose flowers after picking. Second part studied the effect of insect infestation by the same insect on the internal components of the rose flowers which correlated with vase life period of these flowers such as total sugar and total protein. Results showed that the infestation by M. rosae reduced the vase life period of rose flowers after picking at the infested rose flowers compared to control (which non infested by the same insect). Also, results showed that the infestation by M. rosae reduced total sugar and total protein at the infested rose flowers compared to control. Lastly, results showed that the infestation by M. rosae changed the number and arrangement of the protein banding patterns (amino acids) of infested rose flowers petals compared to control.
