Abstract

Not AvailableThe present investigation was carried out to study the biochemical response of monoembryonic and polyembryonic rootstocks seedlings to saline irrigation water. Two rootstocks, Dashehari and Bappakai seedlings were subjected to different NaCl concentration (0, 15.8, 31.6, 37.48 and 74.97 g NaCl/10 kg pot soil). The result indicated that proline content was increased with enhanced salinity level and recorded the highest 0.042 and 0.033 µg/mg with 74.9 g NaCl salinity level in monoembryonic and polyembryonic rootstocks respectively, while total chlorophyll and carotenoids were decreased with increasing salinity level. Reducing sugar and total sugar increased from 0.003 to 0.010 percent in monoembryonic and 0.003 to 0.014 percent in polyembryonic with increasing salinity level from 0 to 74.9 g per pots, whereas starch content decreased in both type embryonic rootstocks. The polyembryonic seedlings was found more tolerant to NaCl by responding increased proline and sugar content, with low decline in chlorophyll and carotenoid content. Thus, polyembryonic seedlings proved to be the more adaptable rootstock to saline conditions.Not Availabl
