rose flower (rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. to study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of alandasht, astane ghods garden, mashhad, iran, during 2009-2010. the first factor was six cultivars of rose flower ...

the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...

Rose plants growing under natural conditions are exposed to unfavorable environmental such as high temperature and drought, particularly around the blooming stage. This can reduce reproductive potential aesthetic value of commercial rose cultivars, which often more sensitive harsh conditions. Plants adjust adverse environments by regulating several morpho-physiological biochemical processes, ke...

The influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘Bianca’ and ‘El Torro’. Third, fourth and fifth nodal explants were cultured on the modified MS medium supplemented with 1.0 and 5.0 mg/l BA. In both the cultivars, higher rate of proliferation (‘Bianca’ 3.75; ‘El Torro’ 2.65) were obtained from the explants distal to the a...

dom’ reached anthesis most rapidly, while plants of ‘Mathilde Gütges’ and ‘Merritt’s Supreme’ were the slowest to f-lower. Table 2 represents days to anthesis and not days to salable color. In general, plants were salable, based on sepal color, ≈10 days before anthesis, so subtracting 10 days from data in Table 2 gives forcing times (from start to sale) for these cultivars when a 62F (17C) mini...
