    Abstract: Hydroxyapatite (Ca10 (PO4)6 (OH)2, HAP) is widely used as a bone graft substitute, potential carriers of drugs and in the purification of proteins, et could be synthesized artificially by various methods but the hydrothermal method at low temperature, which gives a good crystallinity, is often used. Moreover, several studies have shown that, in the... Show More

    Abstract: Stem tip cuttings of Khaya anthoteca seedlings were experimented for the trapping of Arbuscular Mycorrhizae Fungi (AMF). This study aimed to determine the effect of hormone and wounding treatments on the vegetative propagation of K. anthoteca seedlings and the susceptibility of these cuttings to AMF soil inoculums infection compared to some other b...

    Abstract: Plum prefers temperate climate thus a major crop of hills however, it has been found growing from higher hills in Srinagar to Jaipur in Rajasthan and areas around Delhi. It requires less chilling hours and can tolerate frost and high summers both, that is why it can be cultivated in both low temperatures to 0°C and up, highest up to 47°C in summers... Show More
