Sex expression and inbreeding depression in progeny derived from an extraordinary hermaphrodite of Salix subfragilis

Botanical Studies

Table 4 Bootstrap estimates of inbreeding depression (reduction in fitness components of selfed progeny compared with Cross_H: progeny derived from outcrossing with a sibling hermaphrodite and Cross_M: progeny from outcrossing with an unrelated male) in growth, survival and fertility in Salix subfragilis
