Studies on the resistance of apple cultivars to scab, Venturia inaequalis, and determinations of anatomical and biochemical features of resistance


, : Studies on the resistance of apple cultivars to scab, Venturia inaequalis, and determinations of anatomical and biochemical features of resistance. Trudy Instituta Zashchity Rastenii GruzSSR 23: 304-311

Of 391 apple cvs tested, none was completely resistant to scab. They were classified into 4 immunological groups: relatively highly resistant, resistant, susceptible, and highly susceptible. No correlation was found between the thickness of the cuticle or epidermis and resistance.

It is estimated that more than 100 geothermal CO-2 springs exist in central-western Italy. Eight springs were selected in which the atmospheric CO-2 concentrations were consistently observed to be above the current atmospheric average of 354-mu-mo...

The Per1 and Per2 genes are components of the mammalian circadian clock. Mutations in these genes alter phase resetting in response to a nocturnal light pulse, and Per2 mutant mice are known to become arrhythmic in constant darkness. We show that...
