“…But this was not the case for Hezoua pollen from similar site. This is in accordance with previous studies that reported different reaction of different pollen sources to the storage temperature (El Mardi et al, 1996;Mortazavi et al, 2010;Mesnoua et al, 2018). The variation in pollen longevity can be explained by the differences in desiccation tolerance of the pollen (Akond et al, 2012).…”

Date palm pollen storage is becoming more and more necessary due to the asynchronous maturation of male and female flowers that, frequently, occurs, during the last years in Tunisia. However, little information is available on the pollen viability and favorable storage conditions. The present study aims to compare date palm pollen storage at three temperatures (25 ± 2°C, 4° C and −20°C) and to evaluate the aptitude of pollens from different geographical origins to conserve their in vitro germinative potency. Results revealed that, after the fresh pollen, the overall pollen in vitro germinations were significantly improved with storage at −20°C (41.04 ± 23.84%) and 4°C (20.07 ± 22.19%) compared with storage at 25 ± 2°C (4.27 ± 4.39%). For each used temperature, the in vitro germination was not affected by the pollen origins. In fact, almost similar reactions were observed for fresh and stored pollen at 25 ± 2°C and 4°C. On the other hand, pollen stored at −20°C had reacted independently from the origin. However, the aptitude of pollens from similar origins to preserve their in vitro germination potencies under the three storage temperatures reveals some similarities. Physiologic characteristics of pollens were not related to the geographic origins and did not significantly affect their aptitude for storage

“…In view of this, we can conclude that some pollen grains studies are sensitive to storage conditions which explain the decrease even the loss of their germination capacity. The results presented here support numerous publications which found the negative effect of storage conditions in viability, germination and tube growth and elongation of pollen date palm ( Al-Helal, 1994 , El Mardi and Bakheit, 1996 , Damankeshan and Panahi, 2013 , Maryam et al, 2015 ). While, Mesnoua et al (2018) have discussed the effect of temperature storage in pollen germination and pollen fertility.…”

“…The percentage values of germination were between 0.90 and 70.5 %. These values are higher than the values in studies of El Mardi and Bakheit (1996) which vary from 32 to 39 %. In our study, low values and absence of germination were noticed in some male palms.…”

“…This germination medium was composed by 15% Sucrose, 50mg Boric acid, 300mg Calcium nitrate, 200mg Magnesium sulfate, 100mg Potassium nitrate and 100ml of distilled water. Five Petri dishes for each sample were incubated for 24 h at 27 °C ( Boughediri and Bounaga, 1987 , El Mardi and Bakheit, 1996 ). The blockage of germination is done with spraying of 45% Acetic acid ( Mortazavi et al, 2010 ).…”
