STUDIES IN SEEDS AND FRUITS 



ENTADA SCANDENS. 



(Weight of resting seed 400 grains. Shrinking and swelling ratio 2*5, taking the 

 weight of the entire seed as i. Pr. =pre-resting seed ; R. = resting seed ; and Sw. = the 

 seed swollen for germination. ) 



We will commence with the comparison of the regimes 

 of two types of leguminous seeds, that of Guilandina bonducella 

 and that of Faba vu/garis (Broad Bean), the first with im- 

 permeable, the last with permeable coverings. Employing 

 the data given in the table, we get the following results : 



COMPARISON OF THE SHRINKING AND SWELLING REGIMES OF AN 

 IMPERMEABLE AND A PERMEABLE LEGUMINOUS SEED, TAKING THE 

 WEIGHT OF THE PRE-RESTING SEED AS 100. 



Note that the pre-resting seed is the soft seed of the full-grown moist fruit.
