BACKGROUND AND AIMS The gibberellin-insensitive Rht-B1b and Rht-D1b dwarfing genes are known to reduce the size of cells in culms, leaves and coleoptiles of wheat. Resulting leaf area development of gibberellin-insensitive wheats is poor compared to standard height (Rht-B1a and Rht-D1a) genotypes. Alternative dwarfing genes to Rht-B1b and Rht-D1b are available that reduce plant height, such as ...

A factorial experiment with two factors was carried out at the Seed Technology Lab., College of Agriculture, University Baghdad in 2018 order to study effect seed priming gibberellic acid (GA3) (0, 100, 300 and 500 mgL-1) on germination seedling growth deteriorated oat cultivars (Shifaa, Shofan11). The complete randomized design used four replications. results showed that cultivars, soaking dif...

The present study focused on the evaluation of priming with water and various botanical leaf extract followed by humid invigoration as a means to improve seed germination seedling vigour ribbed gourd (COH 1) bitter (CO 1). seeds these gourds were primed extracts at 2% concentration viz., Pongam (Pongamia pinnata L.), Neem (Azadira chtaindica), Moringa (Moringa oleifera), Curry (Murraya koenigii...
