We quantified: 1) the number of infructescences per plant; 2) numbers of verticillasters per infructescence, capsules per verticillaster, and mature and aborted seeds per capsule, 3) seed weight; 4) seed viability; and, 5) seed production in relation to infructescence stem height.
The mean number of total capsules per verticillaster (6.1, SE = 0.21, N= 441) also was not different among treatments across years.
However, the three spray treatments did not increase parameters of seed reproduction, relative to the control treatment: mature capsules per verticillaster (Fig.
Our measurements taken from the pair of leaves just below the first fruit bearing verticillaster avoids the variable of determining the base of the plant.
Further, we found six capsules initiated per verticillaster but only 3.22 capsules maturing to produce seed.
