Many plant species can be cryopreserved by treating shoot tips with complex cryoprotectant solutions before rapidly cooling them to liquid nitrogen temperatures. Plant vitrification solution 2 (PVS2), a commonly selected cryoprotectant, can be lethal with extended exposure times. To determine potentially toxic combinations, we have exposed mint shoot tips to one-, two-, three-, and four-compone...

Restoration and maintenance of soil fertility is a basic but critical ecological problem especially in the tropics where the soils are nutrient deficient particularly P and N. The degraded soils are reclaimed through afforestation programmes with multifarious forest legume tree species along with beneficial microbes. Acacia nilotica, commonly known as Indian Gum-Arabic Tree and locally „Babul‟ ...
