3.1. Growth and yield quality
To evaluate the effect of water stress levels in the reproductive phase,
we defined three levels of drought (75, 50, 25% FC) for oilseed
Camelina in first year. Ultimately results showed that high level of
stress (25% FC) disrupted many flower buds and weren’t collected enough
seed for all of our analyses. So, we followed our experiment without
this level of drought.
Analysis variance indicated that water-deficient during the reproductive
phase significantly affected growth and seed traits (Table 2). Water
stress showed no significant difference in the plant length. The number
of branches increased by approximately 91.7% in B1D2 but remained the
same in the other treatments compared with control. The strongest
decrease in seed number (17%), silique number (9%) and silique length
(12.5%) were found under stress treated-plant in comparison to control.
As shown in Table 2, the highest increase in seed number and silique
number were with 10.3, 10.41% respectively in PGPB treated-plants. It
shows that both of the seed and silique number are in a line under water
deficit and inoculation with PGPB.
Water deficient adversely increased seeds’ weight. As the highest seed
weight is due to inoculated (40%) and non-inoculated (31.8%) plants
under the water deficit (Table 2). As illustrated in Fig 1A, there is a
negative correlation between oil content and seed weight. Adversely,
seed weight with protein and TSC was in a line (Fig 1B, C).
