Title

ASSESSMENT OF CHILLING AND HEAT REQUIREMENTS IN SOME COMMERCIAL CULTIVARS ANDGENOTYPES OF KIWIFRUIT IN THE WEST OF MAZANDARAN

Pages

  85-100

Abstract

 Information about the temperature requirements in fruit trees has an important effect on productivity anddetermining suitable regions for their growing. This research was carried out using single node cuttingstest in a randomized complete block design with three replications in Citrus and Subtropical ResearchCenter in 2015-16. This study was conducted to determine the chilling requirements of HAYWARD andTomuri cultivars and male and FEMALE GOLDEN genotypes using three CHILLING MODELS (Chilling hours, Utah, Dynamic) and their heat requirements using growth degree hours (GHD) method. Results showedthat the chilling requirements of female and male golden genotype buds were 480 and 585 chilling hours, respectively, and for HAYWARD and Tomuri cultivars were 692 chilling hours. The amount of buds heatrequirements in the cultivar and genotype ranged from 2233 GHD in FEMALE GOLDEN genotype to 4066GHD in HAYWARD cultivar. HAYWARD cultivar required 966 hours of chilling requirement for maximumflowering, meanwhile Tomuri, male and FEMALE GOLDEN genotype had a similar chilling for bothvegetative bud break and flowering including 692, 585 and 480 hours, respectively. With continuedsampling, heat requirements reduced and significant negative CORRELATION was found between chilling andheat requirements for bud break. From low chilling requirements of male and FEMALE GOLDEN genotypes, we can deduce that climatic conditions may be not limiting factor in the leading of them in growing area. It is thought that Utah and dynamic models may be more suitable than hour model to evaluate of chillingrequirements.
