Physiological differences of green-leaf and variegated - leaf ivy (hedera helix L.) Cultivars
To screen sun-resistant cultivars of ivy for the three-dimensional greening of urban roofs and balconies, the chlorophyll content, photosynthetic response index, and chlorophyll fluorescence parameters of 5 green-leaf and 5 variegated leaf cultivars of ivy were measured, and compared the photosynthetic characteristics of different cultivars. Results showed that ivy seedlings were very shade tolerant. The photosynthetic adaptation range, maximum net photosynthetic rate, and electron transfer efficiency of the PSII reaction center of the green-leaf ivy cultivars were significantly higher than those of the variegated ivy cultivars. The photochemical conversion efficiency and photosynthetic capacity of Hedera helix ‘Shamrock’ were higher than those of the other tested green-leaf cultivars, suggesting that Hedera helix ‘Shamrock’ had a strong light tolerance. The differences in photosynthetic characteristics among the variegated cultivars were greater than those within the green-leaf cultivars. Among the tested cultivars, Hedera helix ‘Mini Kolibri’ had a relatively high light adaptation range and high light efficiency potential.

期刊介绍：
Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments.
Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December.
Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
