Effect of Irrigation, Sowing Depth and Seed Cover on the Growth and survival Seeds (Pistacia Atlantica Desf.) Koushcan Zanjan Nursery
Wild pistachio forests in terms of the harvesting of various types of products and in terms of energy production and fuel wood are severely exposed to destruction. One of the effective methods for preserving and developing these forests is helping them with artificial regeneration. The purpose of this study was the most appropriate Irrigation, sowing depth and seed cover for seed of Wild pistac...
متن کاملGA3-mediated dormancy alleviation in the reputed African potato, Hypoxis hemerocallidea.
BACKGROUND Hypoxis hemerocallidea, arguably the most well-known medicinal species in South Africa, has been the subject of intensive harvesting from the wild leading to recent conservation concerns. The seeds of this species do not propagate easily and can lie dormant for up to twelve months. MATERIALS AND METHODS In the in vitro germination experiments water, acid and chemical pre-sowing tre...
متن کاملIdeal Sowing Depth for Sweetgum Seed
Seed was collected from a sweetgum tree in Washington County, Miss., in the fall of 1964 and stored at 35° to 40° F. for 4 months. Prior to sowing, the seed was stratified moist for 30 days at the same temperature. About 4 inches of loose silt loam was placed in 4inch clay pots. The soil was settled by sprinkling lightly with water and then leveled. Fifty seeds were placed in each pot and cover...
متن کاملLathyrus (Lathyrus sativus L.) is mostly grown on the residual soil moisture in rice-fallows as utera
277 Lathyrus (Lathyrus sativus L.) is mostly grown on the residual soil moisture in rice-fallows as utera (relay) crop (Gupta and Bhowmick, 2005; Mondal and Ghosh, 2005). But low productivity especially under utera system is the major problem associated with this crop (Bhowmick et al., 2005). Even there is a limited scope for agronomic manipulation under rice-utera system although it has potent...
متن کاملQuantitative Trait Locus Analysis for Deep-Sowing Germination Ability in the Maize IBM Syn10 DH Population
Deep-sowing is an effective measure to ensure seeds absorbing water from deep soil layer and emerging normally in arid and semiarid regions. However, existing varieties demonstrate poor germination ability in deep soil layer and some key quantitative trait loci (QTL) or genes related to deep-sowing germination ability remain to be identified and analyzed. In this study, a high-resolution geneti...
