Abstract

The study was conducted at Indonesian Vegetable Research Institute in March to December  2009 with an  altitude of  1250 masl.  The  objective of study was  to determine the  effectiveness of  EMS  in  producing  carrots male  sterile.  The experiment was arranged in Complitely  Randomized  Block  Design  with  two factors  and three replication.  The results indicate  that the  local  carrot  cultivars have the survival to maturity better than hybrid varieties. The highest percentage of  living  plants  showed  by  carrot  cultivar  origin  Cipanas  (73.21%).  The percentage of live plants is affected by the EMS treatment only until the age of 60 HST.  Increased concentrations of EMS  resulted in  decreased  percentage of  live plants.  Increased concentrations of  EMS  also  tends to  reduce the weight of thousand grains carrot seed produced from the M1 generation. Visual appearance of  pollen  on  all  EMS  treated  the same as the  control, that is  pithy  and  bright yellow. Treatment of  various EMS  concentrations level  provided  the individual has not been effective in producing carrots male sterile. Key words: carrot, male sterile, EMS.

Abstract

This experiment was done at Research Institute for Vegetable, from  January  to Juli 2013. The objective of experiment is to know the fruit number would give the best effect of production, viability and seed vigor of four cucumber lines. The experimental design was split plot  with two replications in the field and three replications in the laboratory for seed. The treatments were two factors; the first was Lines (G); Lines 1 ( G1), Lines 2  (G2), Lines 3 (G3) and Lines 4 (G4).  The second factor was fruit number per plant (t); fruit number per plant inbounded (t0) three  fruit per stem (t1) six fruit per stem (t2) and nine fruit per stem (t3). Results of the experiment sowed that the interaction between fruit number per plan which is left with four cucumber lines. Hybrid line 1 results the highest seed weight per plant, as for hybrid line 3 results the highest seed weight per 1.000 grain, although have the same weight with hybrid line 2. Between cultivars were not significant in vigor of growth and vigor of keeping. The treatment of nine fruit per plant (t3) result the best yield of four cucumber hybrid lines and seed quality was the same treatment with three fruit per plant (t1) and six fruit per plant (t2).   Keywords: Cucumber hybrid lines, fruit number, quality seed, yield

Abstract

Experiment was conducted to find out number of pollination activities and material of artificial pollination on Spring onion seed production. A Factorial Design Randomized Block with 5 replication was set up. The treatments consisted of two levels of number of pollination activities (two and three time per weeks) and two levels of pollination artificial material (soft brush and gun sprayer) and control. Five treatments including control were studied. Research results showed that 3 time per week number of pollination activities with gun sprayer material of artificial pollination significantly increased total yield of Spring onion seed to rainy season in highland.   Keywords: Number of pollination activities, pollination artificial, spring onion.
