    Notes: Summary Natural rapeseed (Brassica napus L.; AACC 2n=38), originated in the temperate climate of the Southwest European Mediterranean region, fails to complete its generative phase in the subtropics and is thus not cultivated in countries like Bangladesh. Adapted agroecotypes are available from the diploid representatives of its genome A (B. campestris/pekinensis, 2n=20) and C (B. oleracea/alboglabra, 2n=18). An artificial resynthesis based on carefully selected progenitor lines was expected to give a photoperiodically better adapted rapeseed. ♀ B. pekinensis x ♂ B. oleracea/alboglabra gave 2 hybrids and 87 matromorphous plants from 1,448 crossed flowers and the reciprocal combination gave no hybrid but 11 matromorphous plants from 2,228 pollinated flowers. The two true hybrids were vegetatively propagated and chromosome doubled. Part of the F2 was grown in Sweden (all plants flowered and the most early ones were selected), part in Bangladesh (13 out of 706 plants flowered). The selected F3 material flowered in Bangladesh and transgressions in earliness could be recorded, some lines were of definite agronomic potential. A correlation in earliness between reaction in Sweden (long day) and Bangladesh (short day) was observed.

    Notes: Abstract Two experiments were conducted in saline culture solution to find out the causes of rolling and bleaching of young leaves of rice, observed previously in experiments on coastal saline-sodic soil. Symptoms similar to those methioned above were observed on young leaves of cv. KS282 in saline culture solution with Na/Ca ratios of 100 or greater. These symptoms were due to Ca deficiency but not of Cu, since Cu concentration was higher in saline shoots than in the control. The decreasing Na/K or Na/Ca ratio in the saline solution decreased Na and Cl concentration in the shoot. In addition to salinity, Na/Ca and Na/K ratios of the growth medium significantly influenced the shoot and root growth of rice.
