Abstract
The study “Identification of Low Temperature Stress Tolerant Ber
(Ziziphus Mauriitiana L.) Cultivars Under Semi-arid Condition” was conducted
during rabi season of 2021-22 at Asalpur Farm, S. K. N. College of Agriculture,
Jobner. The objectives of present investigation were:
1. To evaluate morpho-physiological traits of ber under low temperature stress.
2. To investigate the biochemical and antioxidant activity in leaves of ber cultivars under low
temperature stress.
3. To find out the yield and quality of ber cultivars under low temperature stress.
In this experiment 25 cultivars of ber were used for the identification of low
temperature stress tolerant, medium tolerant and susceptible cultivars under semi-arid
condition. The cultivar used in experiment were saphar chandni,Gola, Tikadi, Thornless,
Katha, Kathabombay, Tabes taso, Mehroon, Dharkhi, Lakhan, Illaichi, Pathani, Chomu local,
Najuk, Kheera, ZG-3, Katha phal, Sukhwani, Ashapuri -2, Supari, Chencho, Khirni, Kumari,
Rashmi and Heera.
Among the ber cultivars Sukhwani proved significantly superior over rest of the
cultivars followed by Tabes taso, Dharkhi and Ashapuri -2 in respect to total chlorophyll
protein and relative water content of ber leaves, leaf burning injury, proline content, cell
membrane injury,fruit deformity, ascorbic acid, peroxidase activity,hydrogen peroxide
content under low temperature stress.
The yield and yield attributes differed significant with each other. Katha cultivar
performed better in terms of yield and yield attributes like fruit size, fruit weight ,pulp stone
ratio and fruit yield in comparision to other cultivars under low temperature stress
condition in semi arid condition.
