Empty Cavity

Empty cavities were found already in very young cucumber fruits with diameter 1.5 cm. As the fruit develops the empty cavities augment and the number of fruits showing this defect increases. Low soil moisture and high nitrogen fertilization favour the formation of empty cavities. Their origination and changes were traced with anatomical methods in the course of fruit development. As a most plausible cause of their origination the author considers the enlargement of only part of the cells of the suture between the two (or three) carples. Due to this uneven enlargement of neighbouring cells strong mechanical tension probably arises amoung them, leading to the formation of ruptures separating these cells, consequently causing the separation of the carpel edges. Besides that, some of the cells of the suture which have markedly enlarged, often burst which also contributes to the formation of an empty cavity and enlarges its dimensions.

The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line (GBS-1) and monoecious lines (Pusa Uday and Punjab Naveen). The F1 and F2 population along with parental lines were evaluated to study the inheritance of this trait. All F1 hybrids showed gynoecious sex in both crosses and in the F2 generation, the observed distribution of plant phenotypes fitted the expected mendelian ratio of 3 (gynocious plant) : 1 (monoecious plant). The segregation of plant sex types suggested monogenic dominant control of gynoecious sex form in cucumber using genotype GBS-1.

Gibberellic acid (GA3) promoted maleness and 2-Chloroethyl phosphonic acid (ethephon) promoted femaleness in cucumber (Cucumis sativus L.) cv Regal 446 seedlings when treated with water, ethephon (250 or 350 ppm) or GA3 (1000 or 2000 ppm) at the l-, 2-, or 3-leaf stage. Seedlings treated with ethephon at all stages produced more female flowers than those with water or GA3 treatments. GA3-treated seedlings produced significantly more male flowers than water treatments, at all developmental stages. The differential response of cucumber seedlings treated at different stages indicated the importance of timing growth regulator applications.
