“…The data on interaction effect of sucrose and STS on fresh weight gain of cut peony stem revealed that Suc 2 × STS 2 was the most effective treatment combination maintaining superiority throughout the period of Heuser and Evensen (1986) in herbaceous peony. Gast (1997), Walton et al (2007Walton et al ( , 2010 also reported that elevated levels of sucrose helped to sustain the flowers better in P. lactiflora cv. "Sarah Bernhardt" by providing external energy source which gets exhausted after harvesting.…”

An experiment was carried out on cut flower Peony cv. "Sarah Bernhardt" to study the effect of pulsing with sucrose and silver thiosulphate on vase life and other parameters. In the trial, sucrose at 3 levels of concentration (0.00, 2.00 and 4.00%) and silverthiosulphate (STS) at 4 levels (0.00, 0.50, 1.00 and 2.00 mm) were tested alone as well as in combination. The experiment was laid out in completely randomized design replicated thrice. The sucrose, 4% and STS 1.0 mm individually recorded higher vase life of 8.93 and 9.36 days respectively. Whereas, their combination (Sucrose 4% × STS 1.0 mm) was significantly superior to the rest of combinations in keeping higher water balance and fresh weight resulting in highest vase life of 10.05 days. This was followed by sucrose 4% × STS 0.50 mm and sucrose 2% × STS 1.0 mm recording 9.57 and 9.18 days of vase life respectively.

“…Bio2 (mean diurnal temperature range) and Bio4 (temperature seasonality) are both related to temperature changes, while Bio8 (mean temperature of the wettest quarter) and Bio14 (precipitation of the driest month) are related to precipitation and its interaction with temperature. P. mairei is a herbaceous perennial with thick carrot-shaped roots that stores carbohydrates in roots that are crucial for bud development and germination (Walton et al, 2007). In P. mairei, a suitable diurnal temperature range might be important for root thickening and further plant development.…”

“…The differentiation of floral buds during autumn until the following spring must go through a period of bud dormancy in cold winter, indicating that plants cease meristem activity and are insensitive to growthpromoting signals for some time before they can resume growth (Rohde and Bhalerao, 2007). Temperature is strictly correlated with flowering in the spring, as well as the geographic distribution of plants (Hall et al, 2007;Walton et al, 2007). The floral transition of plants and other developmental processes depend on changes in photoperiod and low temperature (Park et al, 2015;Zhao et al, 2012).…”

Additional index words. bud development, flower type, herbaceous peony, observation methods of bud differentiationAbstract. The analysis of herbaceous peony (Paeonia lactiflora Pall.) floral bud initiation and differentiation from autumn to early spring is important because flower formation is strictly correlated with flowering in late spring. A clear understanding of peony flower development would allow management practices to be optimized for stable annual production and supply of cut flowers. The aim of this research was to study the timesensitive characteristics underlying flower development in peony cultivar 'Dafugui'. Flower bud differentiation was assessed by paraffin and hand-made slices, as well as stereomicroscopy. Both methods have strengths and weaknesses. Our observations are not entirely consistent with those of previous studies. Flower bud differentiation in 'Dafugui', which starts from late September to mid-April of the following year, is divided into differentiation of the lower parts (separate differentiation periods for the bracts, sepals, petals, stamens, and pistillodes) and upper parts (separate differentiation periods for the petals, stamens, and pistil), and is closely related to annual changes in ambient temperature. Differentiation of lower flower buds takes place before winter dormancy, whereas that of upper parts starts early in the following spring, and finally forms a double-flowered type. The three methods used in this article can be used to study P. lactiflora flower bud differentiation and can contribute to an understanding of this process in the future.
