  We planted experimental trees, namely 6 plum varieties and 6 plum rootstocks in the spring of 2010, which of aim were the phenological -phases of variety-rootstock combinations analyses.

  We observed 18 plum varieties – rootstocks combination in Kecskemét, in Garden of Kecskemét Collage. We set the examination with 2 kind irrigations. A plum combination appear in the examination in 6 repetition depend on irrigation. The vegetative period started bursting of buds in 2011 March 15–18.; 2012 March 16–19. and 2013 March 12.–April 2. This was followed green buds stadium shorter or longer periods, than appeared white buds stadium and in the following day we could see started of flowering. The main flowering kept 7–10 days, except in 2012, when arriving frozen by April 8. morning stopped the main flowering. Following flowering we observed fruit falling 3 occasion, these weren’t noticed calendar date. These were in order: fruit falling after set, fruit falling in June, fruits falling before harvest. In 2013 these fruit falling there weren’t considerable. The ripening was characteristically varieties. The most of earlier ripening was ‘Katinka’/‘St Julien A‘, from which we didn’t harvest in 2011, but in 2012 July 17, and in 2013 July 9. pick up some plum fruits. The ‘Cacanska lepotica’ ripped in July 21–30, this was followed in ripening time the ‘Topfive’ in July 19.–August 6., The ‘Toptaste’ in August 5–23., The ‘Jojo’ in August 2–26., and the ‘Topper and ‘Katinka’/‘Mirobalan ’ stopped ripening in August 22.–September begin. The colouring leaves and the falling leaves started continue after harvesting, but we experienced the end of the falling leaves in the first bigger frozen time, October 24.–November 26.

  We planted experimental trees, namely 6 plum varieties grafted on 6 plum rootstocks in the spring of 2010. Our aim was to observe differences in the fenological-stages of plum rootstock and variety combinations. ‘Cacanska lepotica’, ‘Jojo’,

  ‘Katinka’, ‘Topfive’, ‘Topper’, ‘Toptaste’ plum varieties were planted on ‘Mirobalan’ (Prunus ceresifera var. ceresifera cv. myrabolan); damson (Prunus institicia) – ‘St Julien A’, ‘St Julien GF655/2’; and ‘Wawit’; ‘Wangwnheim’; ‘Fereley’ rootstocks. We observed the bud burst, the flowering course: at the start of the flowering, during the main flowering, and at the end of flowerings and the ripening of the plum. Finally we observed the difference in leaves falling observed in the case of the different varieties and rootstock combinations.

  The bursting of buds started with ‘Cacanska lepotica’, in March 16 and finished with ‘Jojo’ / ‘Mirobalan’ combination, in March 22. The starting of flowering course was in March 29 with ‘Topper’ / ‘St Julien GF655/2’ combinations and the end of flowering course finished with ‘Toptaste’ varieties, in April 3–4. The start of ripening of the plum was with ‘Katinka’ / ‘St Julien A’ combinations, in July 17. and the end of ripening of the plum finished with ‘Topper’ variety. The start of leaves falling began with ‘Cacanska lepotica’, in Sept 5–8 depending on irrigation, and ‘Katinka’, ‘Jojo’ varieties finished, in November 28–29.
