Viruses and Apple Propagation: Why Should I Worry?
نویسنده
چکیده
Several viruses can cause devastating diseases in domestic apple (Malus x domestica Brokh.). Major viruses affecting apple production in New York are apple chlorotic leaf spot virus (ACLSV), apple stem pitting virus (ASPV), apple stem grooving virus (ASGV). These viruses are common and generally latent; in other words, they do not cause acute symptoms on most commercial cultivars. However, when present is susceptible cultivars or in mixed infections, their effect can be economical. Apple mosaic virus (ApMV) and tomato ringspot virus (ToRSV) can also affect apple production in New York. Cherry rasp leaf virus (CLRV) and tobacco ringspot virus (TRSV) are potential threats to apple production in New York.

Impacts of plant growth regulators and culture media on in vitro propagation of three apple (Malus domestica Borkh.) rootstocks
Apple is one of the most important temperate-zone fruit trees in the world. Micropropagation of apple scion and rootstocks is an important method of rapid production of healthy and disease-free plants. In this research, in vitro propagation of three apple roottocks including Azayesh-Esfahan, Morabbaee-Mashhad and M9 was investigated. Shoot proliferation carried out in two basal media (MS and WP...

Abstract Background and Aims: To identify and isolation of viruses a susceptible cell is need which can be primary or line. The use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. IRKHBK cell line was originated from primary cells of bovine kidney by continuous passage. The aim of this study was to introduce the IRKHBK cell ...
متن کاملModeling Static Bruising in Apple Fruits: A Comparative Study, Part I: Analytical Approach
ABSTRACT- Bruising degrades the quality of fresh apple fruits. Reducing bruise damage is of utmost importance in designing and developing processing equipments. The main objective of the present study was to introduce an analytical method to predict the allowable static load applicable to apple fruits. To predict the strain energy absorbed by the fruit, a point load was applied on the solid sph...
